Fancy Coloured Diamonds: Understanding Value and Authenticity

Understanding White Diamonds: Enhancements and Authenticity

Some “white” diamonds undergo enhancements to improve their colour, which can affect their overall value. At the Diamond Certification Laboratory of Australia (DCLA), we prioritize authenticity by thoroughly screening all diamonds that enter our laboratory for any enhancements.

Rigorous Screening Process

Every diamond undergoes an initial screening to detect potential enhancements. If a diamond does not pass this screening, it is referred for further testing to ensure accurate evaluation.

Commitment to Natural Colour Origin

DCLA issues Diamond Grading Certificates and Diamond Reports exclusively for diamonds of natural colour origin. Our stringent certification process guarantees that you receive only the highest quality diamonds, free from artificial enhancements.

Helpful Tips for Selling Your Diamond

TIP #1: Assess Your Sentimental Attachment
Diamonds often carry significant sentimental value for sellers, which may exceed their market value. Before you decide to sell, ensure you are emotionally ready to part with your diamond.

TIP #2: Confirm Quality and Authenticity
It’s essential to verify the quality and grade of your diamond. Many sellers have discovered, too late, that their diamond’s quality differs from what was originally believed. Consider obtaining a report from a recognized laboratory for an unbiased assessment, and ensure the report matches the laser inscription on your diamond to verify its identity.

TIP #3: Determine a Realistic Selling Price
After obtaining an accurate quality report, establish a realistic selling price. Overestimating your diamond’s worth can lead to a frustrating selling experience. An appraiser can help you determine a fair market value. Remember that diamond prices are often quoted in US dollars, so be aware of currency conversion rates when pricing your diamond. For current retail values, consider checking online platforms such as dcladiamondexchange.com.au or bluenile.com.

TIP #4: Explore Your Selling Options
There are various avenues to sell a preloved diamond or diamond jewelry. Research your options to find the best fit for your needs. If time isn’t a concern, online marketplaces or auction houses may be ideal. For a quicker sale, visiting a local jeweler or dealer could be more suitable.

DCLA provides internationally recognized and respected reports for sellers and prospective buyers, ensuring transparency and confidence in the valuation process. Our experienced experts are dedicated to advising you and determining an accurate value for your diamond, safeguarding your interests during the selling process.
