How accurate are jewellery valuations?

The accuracy of jewellery valuations can vary depending on several factors. Here are some key points to consider:

  1. Appraiser’s expertise: The accuracy of a jewellery valuation depends on the competence and experience of the appraiser. A certified gemologist or a professional jewellery appraiser with relevant credentials is more likely to provide a precise and reliable valuation.
  2. Purpose of the valuation: The purpose of the valuation matters. If the valuation is for insurance coverage, it may be higher to ensure full replacement in case of loss or theft. If it’s for resale, the value may be lower as it accounts for market conditions and potential profit margins for a buyer.
  3. Quality of the jewellery: The quality of the jewellery, including the materials, gemstones, craftsmanship, and overall design, plays a significant role in its valuation. High-quality materials and precious gemstones will generally have higher values.
  4. Market conditions: The fluctuating prices of precious metals and gemstones can impact the accuracy of a jewellery valuation. Market conditions change over time, so a valuation today might not hold the same value in the future.
  5. Certification and documentation: Having proper documentation and certifications for gemstones and metals enhances the accuracy of the valuation. This information helps appraisers make more precise assessments.
  6. Appraisal method: There are different methods for valuing jewellery, such as comparison with similar pieces, the cost to replace, or the intrinsic value of materials. Each method has its advantages and limitations.
  7. Local market differences: Valuations can vary across different regions due to variations in consumer preferences and market demands.

It’s important to note that a jewellery appraisal is an expert’s opinion based on their evaluation of the item at a particular point in time. The value assigned to the jewellery may change over time due to various factors, including market fluctuations, changes in demand, or updates in gemstone grading techniques.

555 carat Diamond Bought with Illicit Funds, SEC Says

Cryptocurrency mogul Richard Heart allegedly used proceeds from the sale of unregistered securities to buy the 555-carat Enigma diamond, according to the US Securities and Exchange Commission (SEC).

The SEC has charged Heart — who was born Richard Schueler and who created the Hex cryptocurrency token — with selling the securities to raise more than $1 billion from investors. It alleges that Heart and his PulseChain company committed fraud by misappropriating at least $12 million of those funds to purchase luxury items, including sports cars, watches and the diamond.

“Heart called on investors to buy crypto asset securities in offerings that he failed to register,” Eric Werner, director of the SEC’s Fort Worth regional office, said in a statement Monday. “He then defrauded those investors by spending some of their crypto assets on exorbitant luxury goods.”

The Enigma, which is believed to have come from outer space, is the largest faceted diamond of any kind to appear at auction. Heart purchased it from Sotheby’s at a one-off sale in February 2022 for GBP 3.2 million ($4.3 million). At the time, Heart tweeted that he had bought the stone and would rename it the Hex.com diamond as a nod to his cryptocurrency platform, calling it a “match made in heaven.” Hex has a “5555 day club” comprising people who hold 5,555-day Hex stakes — the longest possible stake in the electronic token.

Sotheby’s, which accepted payment for the Enigma, was not mentioned as a defendant in the SEC’s lawsuit.

“Sotheby’s does not comment on individual transactions, but we can confirm we have established due diligence procedures, tailored and updated to take account of our requirements to conduct business in compliance with applicable laws and regulations,” the auction house stated.

30ct. Pink Diamond Garners Record Sum for Tender House

A 29.52-carat pink diamond went for more than $8 million at South Africa-based Pioneer Diamond Tender House, the highest price for any stone the company has sold.

The fancy-vivid-pink, type II rough — named the Protea Pink after South Africa’s national flower of the same color — raked in $271,307 per carat, Pioneer said Wednesday.

A junior mining company recovered the diamond from a deposit on the banks of the middle Orange River, according to Lyndon de Meillon, a shareholder in Pioneer. The stone is believed to come from a 90 million-year-old Lesotho kimberlite that broke off and made its way down the river, where it got trapped in a terrace approximately 500 kilometers from its original location, he explained.

“This unique diamond…once again showcased why the alluvial diamond deposits of South Africa represent the highest and most consistent value-per-carat diamond supply in the world,” de Meillon added.

Junior miner recovers spectacular pink diamond from banks of Middle Orange River

JOHANNESBURG- A junior diamond mining company has recovered a spectacular pink diamond from the banks of the Middle Orange River.

The diamond, named Protea Pink, is a fancy pink, 29.52 ct type II diamond, with unusual depth of colour and exceptional clarity. Its colour is reminiscent of the pink hues found in South Africa’s national flower, the protea.

This diamond was most likely derived from the 90-million-year-old Lesotho kimberlites and made a remarkable journey down the Orange river to be trapped in an ancient river terrace, approximately 500 km from its source, South African Diamond Producers Organisation (Sadpo) vice-chairperson and geologist Lyndon de Meillon stated in a release to Mining Weekly.

Sadpo, an organisation that aims to streamline the diamond diggers industry, is headed by CEO Yamkela Makupula, who is a director of Pioneer Tender House, where Protea Pink will be sold on tender in South Africa during the week of 26/30 June. The sale will end on Friday 30 June.

The Middle Orange River, which is known as the area with the highest average value per carat in the world, also has the lowest grade in carat per hundred tonnes of any area actively mined, De Meillon explained.

The modern-day alluvial diamond miner utilises no chemicals in the recovery process and rehabilitation of the mining areas has been proven to improve the carrying capacity of the land, De Meillon added.

Unemployment rates in the area are alarmingly high, exceeding 70%, with mining operations, such as this one by a junior miner, playing a crucial role in supporting the local economy by providing job opportunities and stimulating economic growth.

The revenue generated from diamond mining can contribute to infrastructure development, education, healthcare, and other essential services in the community.

De Beers Sales Slide as Slow Trading Continues

De Beers’ sales value fell this month as global rough demand weakened and the miner reduced prices of its larger stones.

Proceeds dropped 32% year on year to $450 million at 2023’s fifth sales cycle from $657 million in the equivalent period a year earlier, De Beers reported Wednesday. Sales declined 6% compared with the $479 million that the fourth cycle brought in. The total included the June sight as well as auction sales.

“Following the JCK [Las Vegas] show, and with ongoing global macroeconomic challenges continuing to impact end-client sentiment, the diamond industry remains cautious heading into summer,” said De Beers CEO Al Cook. “Reflecting this, we saw demand for De Beers rough diamonds during the fifth sales cycle of the year slightly softer than in the fourth cycle.”

De Beers lowered prices at the sight by 5% to 10% mainly in 2-carat categories and larger, as well as for some 1- to 1.5-carat items, market insiders said. It also extended its buyback program, which allows sightholders to sell goods back to the miner following the purchase.

This reflected weakness in the rough that produces polished above 0.30 carats, and especially the stones that yield 1-carat finished diamonds. These sizes are especially weak in the US market amid economic uncertainty and a lull in engagements, dealers explained. Rough under 0.75 carats has seen a mild recovery as Indian manufacturers look to fill their factories with low-cost material.

55 Carat Ruby, 10 Carat Pink Diamond Each Fetch A Record $34.8 Million At Sotheby’s

The just completed Sotheby’s Magnificent Jewels sale in New York is the first auction to sell two items for more than $30 million.

The first is the “Estrela de Fura,” a 55.22-carat Mozambique ruby that sold for $34.8 million ($630,288 per carat), establishing a world record price for a ruby and any colored gemstone sold at auction. It is also the largest ruby to be sold at auction. Its pre-auction estimate was more than $30 million.

The finished ruby was cut and polished from a 101-carat rough discovered by Fura Gems, a colored gemstone mining and marketing company based in Dubai. It was unearthed at its ruby mine in Montepeuz, Mozambique, in July 2022. The company named the rough gem, Estrela de Fura (Star of Fura in Portuguese). Even in its rough, untouched state, the ruby “was considered by experts as an exceptional treasure of nature for its fluorescence, outstanding clarity and vivid red hue, known as ‘pigeon’s blood’ — a color traditionally associated only with Burmese rubies,” Sotheby’s said in a previous statement.

The 10.57-carat "Eternal Pink” diamond

It’s rare for a mining company to cut and polish the gem and then sell it at auction. The usual route of recently found colored gems is to sell it to a company as a rough where they would cut and polish the gem, then it would sell it privately or at auction. However, Dev Shetty, founder and CEO of Fura Gems, chose to not only go on the auction route on his own, but to embark on a worldwide tour of the rare gem, promoting not only this stone, but rubies from Mozambique as equal to rubies from Burma, which has historically been considered the main source of the most sought-after rubies.

Quig Bruning, head of Sotheby’s Jewelry America, previously said the Estrela de Fura may signal a change of this perception.

“It is undoubtedly positioned to become the standard bearer for African rubies – and gemstones in general, bringing global awareness to their ability to be on par with, and even outshine, those from Burma,” Bruning said in a statement.

Tiffany’s tickled pink to be grabbing the world’s last Argyle diamonds

“This is truly once in a lifetime,” says the jeweller’s chief gemologist of the 35 sparklers acquired from the now-closed mine in the Kimberley.

Vicky Reynolds wants to take you on a date with a diamond.

Reynolds, Tiffany & Co’s chief gemologist, has had the enviable task of chaperoning the final 35 Argyle diamonds sold around the world, meeting with potential buyers and discussing exactly how these incredibly rare and exceptional gemstones will be used.

It is, she says, “the stuff my dreams are made of. This is truly once in a lifetime.”

Reynolds has worked with New York-based Tiffany & Co since 1987 – almost as long as the Argyle diamond mine, owned by Rio Tinto, operated in Western Australia’s East Kimberley region (it opened in 1983). When the mine closed in 2020 due to finite resources, the final annual tender – ordinarily a highly anticipated and prestigious event on the gemstone calendar – was considered the hottest ticket going.

The Argyle mine produced 90 per cent of the world’s pink diamonds, and each year, only 50 to 60 were ever offered in an invitation-only tender process. So when Rio Tinto rang Reynolds after the tender, to offer Tiffany and Co a further 35 diamonds noted for their vivid pink and purple colour, she jumped at the chance.

Rio Tinto unveils Argyle Rose heirloom piece

Rio Tinto has unveiled the latest heirloom piece of Argyle Pink Diamonds jewellery, featuring one of the last diamonds to be mined from the iconic Argyle mine in the East Kimberley, Western Australia.

Mining ended at Argyle in November 2020, after 37 years of uninterrupted production, during which the mine became the source of about 90% of the world’s prized rose-to-magenta hued stones. The mine produced more than 865 million carats of rough diamonds.

Designed by Western Australian jeweller Solid Gold Diamonds, the Argyle Rose features a total of 3.25 carats of rare Argyle pink and blue diamonds encrusted in a rose motif, surrounded by white diamonds and hand-set in platinum and 18 karat gold.

The heart of this piece is an extremely rare 1.36 carat, Fancy Deep Pink radiant cut diamond. It is just one of twelve radiant cut diamonds over one carat with a colour grading, 1P, from the last 30 years of production from Argyle.

The surrounding petaled design of pink and blue Argyle Diamonds totals 1.89 carats, together with 2.80 carats of white diamonds. The Argyle Rose is for sale at Solid Gold Diamonds in Perth for A$2 million.

“I am delighted to launch the Argyle Rose. Encapsulating a rich history and an extraordinary provenance, it is both a contemporary treasure and an heirloom for tomorrow,” Sinead Kaufman, Chief Executive of Rio Tinto Minerals said in a statement.

“These rare and precious diamonds are one and a half billion years old, from one of the most beautiful places on earth, and the world is simply not producing them anymore.”

Breakthrough Tech ‘Pinpoints Origin of Every Diamond’

A Swiss company claims it has developed technology that chemically profiles any diamond so it can identify the country – and even the specific mine – of origin.

Spacecode says it analyzes diamonds at a molecular level to determine where it was mined, so it doesn’t matter whether the stone has been registered earlier in the supply chain.

The company has been in talks with the G7 and EU nations about the possibility of using its technology to identify Russian diamonds.

“Our research started 10 years ago, but over the past three years we have developed a specific technology that identifies the provenance of any diamond,” said Pavlo Protopapa the company’s CEO.

“We are the first ever to hold such unique technology, which is a major game changer all along the diamond supply chain.”

“We plan to produce by the end of this year our initial units. By 2024, we will offer on a large scale to the global diamond and jewelry industries, a small easy-to-use device that will define the country of origin of rough and polished diamonds.”

Protopapa added that “in meetings with the G7 and the EU representatives, we have received enthusiastic interest. Within months, we will deliver a small, easy-to-use device that will identify Angolan, Botswanan, South-African and of course, any Russian diamonds. We will leave it for the politicians to decide what to do with it”.

Spacecode’s breakthrough technology analyzes the chemical composition of a diamond on a molecular level, and with Artificial Intelligence tools, creates a “chemical profile” of the run of the mine of a specific diamond mine.

The technology identifies not only the country of origin, but even the specific mine in which it was mined.

Spacecode’s diamond inventory management technology already tracks more than 25 million stones. The company has a team of 15 engineers and specialists, and over 300 clients.
Its technology could be adopted by the G7 and the EU to impose effective sanctions on both rough and polished diamonds from Russia.

It could also be used by the Kimberley Process and other organizations, to end, for example, the export of Angolan diamonds through other African countries.

Are Laboratory-Grown Diamonds Really Sustainable and Eco-Friendly?

Diamonds have long been revered for their beauty, rarity, and association with luxury. However, traditional diamond mining comes with ethical concerns and environmental impacts. In recent years, laboratory-grown diamonds have emerged as an alternative, marketed as a sustainable and eco-friendly choice. This article explores whether laboratory-grown diamonds truly live up to their claims of sustainability and environmental friendliness.

The Process of Laboratory-Grown Diamonds:
Laboratory-grown diamonds, also known as synthetic or cultured diamonds, are created in controlled environments using advanced technology. They are produced through two primary methods: High-Pressure High-Temperature (HPHT) and Chemical Vapor Deposition (CVD). Both methods involve replicating the natural conditions that cause diamond formation but in a shorter time frame.

Environmental Impact:
a) Land Disruption: Traditional diamond mining often requires extensive land clearing and excavation, leading to habitat destruction and soil erosion. In contrast, laboratory-grown diamonds are produced in labs, eliminating the need for land disruption.

b) Energy Consumption: The production of laboratory-grown diamonds does require significant energy inputs, mainly in the form of electricity. However, advancements in technology have made the process more efficient, reducing energy requirements over time. Renewable energy sources can also be used to power these facilities, further minimizing their carbon footprint.

c) Water Usage: Traditional diamond mining can consume substantial amounts of water, contributing to local water scarcity and ecosystem degradation. Laboratory-grown diamond production generally requires significantly less water, making it a more environmentally friendly option.

d) Chemical Usage: While the production of laboratory-grown diamonds involves the use of chemicals, the industry is continually striving to reduce their environmental impact. Responsible manufacturers are working on developing greener chemical processes and minimizing the use of harmful substances.

Ethical Considerations:
Traditional diamond mining has long been associated with human rights issues, including exploitative labor practices and conflicts (so-called “blood diamonds”). Laboratory-grown diamonds, on the other hand, offer a more transparent and traceable supply chain. Consumers can be confident that their diamonds are not contributing to human suffering or funding conflicts.

Long-Term Sustainability:
a) Repurposing Waste: Laboratory-grown diamond production generates significantly less waste compared to mining. Additionally, by-products from the manufacturing process can be repurposed, further reducing the ecological impact.

b) Circular Economy: As laboratory-grown diamonds gain popularity, a potential future advantage lies in their ability to be recycled and repurposed. This aligns with the principles of a circular economy, where materials are reused rather than discarded.

Conclusion:

Laboratory-grown diamonds offer an alternative to traditional diamond mining that addresses many of the ethical and environmental concerns associated with the industry. While there are energy and chemical inputs involved, the overall impact is significantly reduced compared to mining. Furthermore, the transparency and traceability of laboratory-grown diamonds provide assurance to consumers seeking an ethical and sustainable choice.

As with any industry, continuous improvements are needed to enhance the sustainability of laboratory-grown diamond production. Manufacturers should prioritize the use of renewable energy, minimize chemical usage, and explore recycling options. By doing so, laboratory-grown diamonds can truly become a more sustainable and eco-friendly option, offering consumers the beauty and luxury they desire without compromising the environment or human rights.
