OUR GEMOLOGIST CHECKS EVERY GEMSTONE
Trained by the world’s leading authority on gemology, the Gemological Institute of America (GIA), our gemologist Mark Yakubov graduated with honors in 1996.
Since then Mark has performed gem identification on thousands of faceted and rough colored gemstones, and antique and contemporary jewelry pieces.
Mark is a diamond expert who as the former Laboratory Director of the International Gemological Institute conducted research in all areas in gemology. Mark has been seen on Good Morning America, Fox News, CBS, and NPR discussing the subject of synthetic diamonds.
While being taped live with his colleague David Weinstein, Mark were able to identify which diamonds were synthetic and which ones were created by nature.
As a buyer, you make your purchase on I Do Now I Don’t with complete confidence. Our gemologist Mark Yakubov certifies that the diamond and gemstone jewelry is exactly as described in the seller’s listing. This evaluation is particularly important because of the variability in the 4Cs of diamond value (color, clarity, cut, and carat weight).
The two letters after a gemologist’s name—G.G.—stand for Graduate Gemologist, and are recognized worldwide as the mark of a highly trained and ethical professional in the jewelry industry.
In addition to creating the 4Cs of diamond value (color, clarity, cut, and carat weight), the GIA has graded some of the most famous diamonds in the world, including the Hope Diamond (45.52 carats), the Taylor-Burton Diamond (69.42 carats) and the De Beers Millennium Star (203.04 carats)
