A diamond certificate is simply a detailed description of the diamond’s characteristics, such as its cut, color, clarity, and carat weight. It is not a warranty, guarantee, or valuation. Many consumers mistakenly believe that a certificate assures the diamond’s quality or its worth in the market. Always use the certificate as a reference, but don’t rely on it as the sole indicator of a diamond’s value.

Personal viewing of diamonds is essential to accurately assess quality differences. Differences that might seem subtle on paper—such as the distinction between a ‘G color SI1 clarity’ and a ‘G color VS2 clarity’ diamond—are often hard to detect with the naked eye. However, the price difference can be substantial.Tip: Save money by comparing stones in person to avoid paying more for subtle variations.

It’s a common misconception that diamonds with SI1 and SI2 clarity grades have visible inclusions. In many cases, these inclusions are microscopic and cannot be detected by the naked eye. Diamonds in these clarity grades offer fantastic value, as they are often priced lower than higher-clarity diamonds but look nearly identical. Don’t automatically assume that a VS2 clarity or higher is the only option for quality—SI1 and SI2 can be excellent choices. Especially if you're considering a round brilliant cut, radiant cut, oval cuts, cushion cuts and marquise cuts.

Don’t assume that two diamonds with the exact same carat weight will look identical. For example, a 2.00-carat diamond priced at $8,000 may not have the same visual impact as a 2.00-carat diamond priced at $12,000. Factors like cut quality, shape, and proportions play a significant role in how a diamond appears face-up. Ensure that you assess the diamond’s overall visual appeal and not just its carat weight.

There is no universally accepted, purely scientific method for grading diamonds. While there are industry standards, grading can vary from one gemologist to another, and even across different laboratories. We’ve seen diamonds graded differently by various jewelers and appraisers, which is why it's essential to look at the diamond yourself and use the certificate as a guideline rather than the final word.

When buying a loose diamond, don’t settle for just any jeweler. Seek out professionals with extensive experience and knowledge. Experts with international buying experience, such as those who have been in the business for decades, will be able to offer you insights that help you make the best choice. Don’t hesitate to ask for guidance—they can provide invaluable assistance in navigating your options.
