Jennifer Lopez, who recently settled down things with ex-husband Ben Affleck, has reportedly walked away from her divorce, holding onto dazzling green diamond worth $5 million.

Daily Mail has revealed that the 55 year old star will be keeping her stunning green diamond engagement ring from ex-lover.

The ring is a real showstopper, featuring a big green diamond in the center which is framed by two long baguette cut diamonds and finished.

When Ben proposed to Jennifer, she gushed about the green gem, calling it her symbol of luck and the new beginnings in her life.

As per TMZ, the Atlas star is said to be keeping all the things and jewelry given by the Batman actor.

However, insiders further suggested that Lopez sees the piece of art more than just a ring, as it may be her way of holding on to cherished memories while also turning the page to a new chapter.

Jennifer Lopez and her ex-beau Ben Affleck have finally called it quits after giving their romance a second chance. The pair, who tied the knot back in 2022, tried to make things work out between them but they didn’t work in their favor.

Antwerp Diamond Polishers Develop Device That Uses AI to Grade Colored Stones

Chroma Diamonds founded by Alexander Appels and Jan De Henau is a relatively new company in the Antwerp diamond district, which specializes in colored diamonds. Stymied by the relatively “subjective process of color grading”, the 2 have set out on a mission to develop a device that provides more objective measurements for the grading of colored stones.

The device will utilize AI gathering data points and becoming smarter with each new set of inputs. They believe with sufficient time the device would learn enough to be able to more accurately grade certain stones, especially in resolving cases where certain grading criteria place the value of diamond on the edge of a color category but not quite enough to satisfy it being classified in the next grade above.

“Customers come to us with high expectations. After all, the value of their diamond is determined by, among other things, the color and intensity of that color, and let it (partly) depend on the cut and the people in the grading office, we hear. Because it is they who assign the diamond an official color, and therefore also determine its value definitively,” explains Appels.

Though this idea is not new to the Diamond District the duo has taken things one step further receiving support from the innovation process of the City of Antwerp. They plan on using and testing the device in their own business first as proof-of-concept before taking it to the greater market.

A Rare and Unique Natural Treasure
A green diamond is a diamond that exhibits a natural green body colour, making it one of the rarest and most sought-after coloured diamonds in the world. For a diamond to be classified as a true green diamond, green must be the dominant hue, although it may have secondary modifying tones of yellow, blue, or grey.

These remarkable diamonds owe their distinctive green hue to exposure to natural radiation deep within the Earth’s crust over millions of years. The radiation interacts with the diamond’s atomic structure, creating unique structural defects that result in its green coloration. Because of the highly specific and rare conditions required for their formation, natural green diamonds are exceptionally rare and valuable.

Formation of Natural Green Diamonds
Unlike most coloured diamonds, which owe their colour to trace elements (such as boron in blue diamonds or nitrogen in yellow diamonds), green diamonds derive their colour from natural irradiation.

How it Happens:

Natural Radiation Exposure: Over millions of years, the diamond is exposed to radioactive minerals such as uranium or thorium in the Earth’s crust.
Structural Alterations: The radiation disrupts the arrangement of carbon atoms in the diamond’s crystal lattice, creating a “radiation-induced colour centre.”
Absorption of Light: These defects allow the diamond to absorb red and yellow light, making the diamond appear green to the human eye.
Key Fact: The green colour usually forms on the surface of the rough diamond, which means that careful cutting is required to preserve the colour in the final polished gem.

Shades & Intensity of Green Diamonds
Like all fancy-coloured diamonds, green diamonds are graded based on hue, tone, and saturation. The most valuable green diamonds have a pure green hue with strong saturation. However, many natural green diamonds exhibit secondary modifying tones that affect their final colour.

Green Diamond Colour Classifications:
Colour Name Description Common Secondary Hues
Fancy Light Green Soft, pastel green colour Yellow, Grey
Fancy Green True green with medium saturation Yellow, Blue
Fancy Intense Green Vibrant, rich green hue Blue, Yellow
Fancy Vivid Green Deep, highly saturated green Minimal or No Modifying Tones
Fancy Deep Green Darker green with strong depth Grey, Yellow
The rarest and most valuable green diamonds are those with a strong, pure green hue and minimal secondary modifiers.

Famous Green Diamonds
Due to their rarity, natural green diamonds have become legendary in the world of gemstones. Some of the most famous examples include:

The Dresden Green Diamond (41.00 ct)

One of the most famous and largest natural green diamonds in existence.
Weighing 41.00 carats, it exhibits a pure green colour with exceptional clarity.
Believed to have originated in India, it is now housed in Germany’s Green Vault museum.
The Aurora Green Diamond (5.03 ct)

The largest Fancy Vivid Green diamond ever auctioned.
Sold for $16.8 million at Christie’s in 2016.
The Ocean Dream Diamond (5.51 ct)

A unique blue-green diamond with a distinctive Fancy Deep Blue-Green colour.
Exhibits a combination of radiation exposure and boron content.
The Chopard Green Diamond (10.02 ct)

A Fancy Intense Green diamond set in a ring by Chopard.
One of the most valuable green diamonds in the world.
How Are Green Diamonds Graded?
Green diamonds are graded based on the 4Cs (Carat, Colour, Clarity, and Cut), with special emphasis on colour intensity.

Hue: The primary colour must be green, though modifying hues like yellow, blue, or grey may be present.
Tone: Determines how light or dark the green appears.
Saturation: The strength or intensity of the green hue—more saturated stones are more valuable.

Laboratories like the GIA (Gemological Institute of America) and DCLA (Diamond Certification Laboratory of Australia) provide certificates to verify a green diamond’s natural origin.

Treated vs. Natural Green Diamonds
Because natural green diamonds are incredibly rare, some diamonds undergo treatments to enhance or artificially create a green hue. These treatments include:

Radiation Treatment – Exposing diamonds to artificial radiation to mimic natural colouration.
HPHT (High Pressure, High Temperature) Processing – Alters the internal structure to change colour.
Coating – Applying a thin layer of green material to the diamond’s surface.
Key Buyer’s Tip: Always verify that a green diamond’s colour is natural by requesting a grading report from an independent, recognised gemological laboratory (such as DCLA or GIA).

Are Green Diamonds a Good Investment?
Extreme Rarity – Natural green diamonds are among the rarest coloured diamonds, making them highly desirable.
High Market Demand – Prices for Fancy Vivid Green diamonds have consistently increased over time.
Auction Record Breakers – Green diamonds regularly fetch millions at auctions.

The most valuable green diamonds are Fancy Intense or Fancy Vivid Green with minimal secondary hues and strong saturation.
