FAQ
The more you know, the easier you can distinguish between an ordinary stone and an exceptional one. Understanding the Basics of the 4C’s (Colour, Clarity, Cut & Carat) as well as Fluorescence is a key on the subject of selecting and purchasing a diamond. A slight variation in its specifications (despite having the same 4Cs) can change drastically its value, its rarity and its quality.
We also generally recommend Hearts & Arrows Cut to all our Clients. H&A is a highly sought for Ideal Diamond which ensure the best brilliance and sparkle, even a 3 Excellent Cut Diamond does not guarantee an Ideal Cut. H&A Diamonds can cost an additional 10-15%, that's why many Jewelers do not mention it.
For more information, please refer to the Guide on 4C’s of Diamond Quality and Fluorescence Guide provided by GIA.
A diamond certificate certifies the authenticity, integrity and grades of your diamond. Diamond certification is a process where an unbiased independent gem lab tests and assesses the quality of a diamond. The lab issues a written report about the diamond. Each report has its own number which is kept on file at the gem lab and a copy is sent back with the diamond. A GIA or IGI certified diamonds includes a microscopic laser inscription of their certification number on the outer edge of the diamond (i.e. at its girdle).
GIA (Gemological Institute of America) Diamond Certificate offers you the best grading and most protection for your special investment. The GIA is the most reputable laboratory out there and is in fact the founder of the Diamond 4Cs Grading that all the other laboratories are using. GIA prepares the strictest natural diamond certification out there. So, there is no question that the diamond grade on your certificate is the actual quality of your stone.
For Lab Grown Diamonds, IGI (International Gemological Institute) is the most reputable laboratory to grade man-made diamonds. IGI was the first to debut certification for man-made diamonds 16 years ago. Today, they remain the most comprehensive certification for Lab Diamonds, including the individual growth process of the CVD or HPHT stone. They will also indicate, specifically, stones as either “as grown with no indication of post-growth treatment.” or as “may include post-growth treatment.”
