When DeBeers launched their “Diamonds Are Forever” campaign in the 1940s, it changed the world of romance. Suddenly, the diamond became the symbol of love and commitment. Decades later, we realize that romance, love, commitment, and relationships have evolved. But the diamond remains a constant. 

Not only is a diamond a natural choice for romantic relationships (e.g. engagement, wedding anniversaries), it is a perfect selection for people who gift and self-gift for important life events (e.g. graduations, promotions, the launch of a new business, a birthday when you look and feel amazing!). 

When the sentiment and the occasion are real, real is what matters. This is why many consumers are concerned about natural diamond certification. It is all about being informed and educated about your purchase decisions so you can derive maximum value and satisfaction.

How are Natural Diamonds Certified?

The Natural Diamond Certification Process

When you purchase a diamond, it should come with a grading report. This covers the 4 C’s - cut, color, clarity, and carat weight and is a marker of authenticity as a third-party lab has evaluated and verified its quality. 

You have no doubt heard of GIA, or the Gemological Institute of America. This is arguably the most well-known, and well-respected labs in the country and on the international scene. There are, however, others that are reputable and will issue impartial accurate grading reports. They include:

  • American Gem Society (AGS)
  • European Gemological Laboratory (EGL)
  • International Gemological Institute (IGI)

These organizations engage in scientific research, and grading is conducted by experienced gemologists who are trained in the art and science of analyzing a diamond’s key attributes. Diamond sellers or even private individuals pay the labs to certify their stones. 

Why is natural diamond certification important? As mentioned, certification is critical in that it verifies that you have received the quality and value that you intended when you purchased the diamond. Certification also:

  • Gives you reliable evidence with which to make an informed purchase decision. You’re not relying on a sales pitch or being bewitched by sparkle and shine. Buying a diamond is often a sentimental and emotional process - but with a grading report and certification, you add in the crucial element of logic and rationale. 
  • Increases the value of the diamond. Certified stones are more valuable than non-certified stones. This is important for vendors, but also for individuals in terms of insurance purposes and other practical matters.
  • Makes it much easier to compare diamonds. In a sense, you are comparing apples to apples and making a solid decision. For example, you can compare diamonds with similar carat weights but with differing cuts and clarity to determine which aspects are most important to you.
  • Builds peace of mind among consumers. You can shop with confidence, equipped with the knowledge and third-party verification.

Is a natural diamond certification the same as a diamond appraisal? Imagine walking into a jewelry store; the retailer gives you an appraisal instead of a certificate. No! There is a big difference. The appraisal gives you the monetary value of the stone or the piece. Yes, this is important because it impacts how much you pay initially and for insurance. It is useful to know. 

A certificate does not give a monetary value to the stone. It does not tell you that Stone A is worth $X while Stone B is worth $Y. Instead, it documents the key attributes of the diamond and grades for color, clarity, cut, and carat weight. The market fluctuates, and prices rise and fall. The grading report, however, remains the same. 

So while an appraisal is a helpful document, it does not, and should not, replace a natural diamond certificate.

Purchase with Confidence

Natural diamond certification is an important step in the purchase process for both vendors and consumers. It frees you from sales pitches and allows you to focus on the characteristics and qualities of the diamonds you are considering so you can make the best decision for your needs and price point.

Traditionally, melee diamonds have not been certified by labs like GIA because of their small size. However, it is just as essential that you verify whether or not these stones are authentic. 

According to GIA, more than 200,000 carats of HPHT melee lab grown diamonds are manufactured each month. With some suppliers, you risk having lab grown mixed in with natural melee.
