The #1 Place to Buy Engagement Rings and Diamond Eternity Bands
We send all our diamonds jewelry to GIA for certification because they are the gold standard world wide for diamonds. Since established in 1931, GIA has proved themselves as the world’s foremost grading and certification authority on diamonds, colored stones, and pearls. As a nonprofit institute, GIA is the leading source of knowledge, standards, and education in gems and jewelry. In 1953, the GIA developed its International Diamond Grading System and the Four Cs (cut, clarity, color, and carat weight) as a standard to compare and evaluate the quality of diamonds. The key to GIA– they don't buy, sell, trade or cut diamonds – they don't value (how much is my diamond worth?) so there is no conflict of interest, ulterior motives for higher or lower grading. Multiple diamond gemologists score each diamond and must agree. This avoids "pay offs", dishonest deals for exaggerated color or clarity grading. Their integrity over the years has earned them the ‘Gold Standard’ reputation worldwide. When you want to sell your GIA Diamond to a certified dealer look to Gray & Sons. Our Miami showroom in Miami beach across from Bal Harbour shops is the top buyer and seller of all GIA certified diamond studs and diamond engagement rings .
Why GIA Diamonds?
The Gemological Institute of America – The Gold Standard Worldwide for Diamonds. The GIA Laboratory provides a variety of gem grading and identification reports. Diamond grading reports for unmounted natural diamonds determine their key characteristics: color, clarity, cut and carat weight. With current deceptive practices all over the world today it is most important to buy a diamond with a GIA certificate to guarantee that you are not buying a man made diamond, or a diamond that has been treated with high heat and pressure to enhance the color ( HPHT ). GIA issues a complete Diamond Grading Report. Gray & Sons goes an extra step and pays GIA to engrave the certificate number on the diamond after grading – to offer our customers peace of mind to know – the “Pedigree” delivered with their diamond is really for THAT diamond. We’re the only jeweler in all of Miami Beach to offer this deal!
