How do I know it's a fair price?
This is one of the most common questions men ask when buying an engagement ring for the first time. And a very fair question. The jewelry market can be opaque. The same diamond weight, the same setting color - and prices differing by half. How is this possible?
The answer is simple: the same stone can be described in different ways. A brilliant-cut diamond can be broadly described as a '0.5 carat diamond' or precisely as a '0.50 CT brilliant-cut diamond, E color, VVS1 clarity, GIA certificate number XXXXXXXXX'. The difference between these two descriptions is the difference between buying blind and buying with full knowledge.
A GIA certificate is your insurance policy against overpaying and dishonesty.
What is GIA and why is it trustworthy?
GIA, or the Gemological Institute of America, is an independent, non-profit gemological institute founded in 1931 and headquartered in the United States. It is recognized as the world's most reliable source for diamond evaluation and certification.
One word is key: non-profit. GIA does not sell diamonds, nor is it affiliated with any jeweler or jewelry retailer. Their sole task is the precise and impartial evaluation of stones. This is why a GIA certificate is accepted and recognized worldwide - from New York to Tokyo.
If a jeweler offers their own certificate or a certificate from a lesser-known institution instead of GIA, it's a red flag worth noting.
The 4Cs Scale - how are diamonds graded?
GIA grades diamonds according to the 4Cs system, which they themselves created and popularized worldwide. The four Cs are: Color, Clarity, Cut, and Carat.
Color is graded on a scale from D to Z, where D signifies a perfectly colorless stone, and the further down the alphabet, the more yellowish tint. BELLER diamonds have a color grade of D-F, which is the highest available category.
Clarity is graded under 10x magnification. The scale starts from FL (flawless - no inclusions) and ends at I3. BELLER brilliant-cut diamonds have VVS1 clarity, meaning very, very slight inclusions that are not visible to the naked eye.
Cut describes the proportions and precision of the cutting. A good cut is essential for the stone's full brilliance. Weight is given in carats (CT), where 1 carat = 0.2 grams.
How to verify the authenticity of a GIA certificate?
Every diamond certified by GIA has a microscopic report number engraved on it. You can only see it under a jeweler's loupe, but it is there. The same number appears on the paper certificate.
GIA provides a free Report Check website (reportcheck.gia.edu) where you can enter the number and verify the authenticity of the report and detailed stone data. If a jeweler refuses to show the certificate or the number cannot be verified in the GIA database - do not buy.
At BELLER, every engagement ring purchase includes an original GIA certificate. We present it during your visit to the atelier and explain what each parameter means in practice.
