A diamond certificate is a detailed document that specifies unique diamond specifications like its color grade, carat weight, cut grade, and clarity grade. A certificate from a gemological laboratory verifies the quality of a loose diamond and allows non-experts to make educated diamond buying decisions. Therefore, purchasing a diamond without a diamond certificate or without the jeweler's authenticity certificate that discloses the Diamond value would not be a wise decision to make. At Jewelry Diamond Expo, we rely on some highly regarded, internationally acclaimed gemological laboratories who uses globally renowned standards for diamond grading to certify every loose diamond we offer.
GIA or the Gemological Institute of America is a non-profit, independent organization. It was founded in 1931 and is considered by many to be the world's highest authority in gemology. Their diamond and gemstone grading system was introduced in 1953 and is recognized worldwide. Manufacturers from around the world send gems and diamonds to GIA for evaluation and analysis. A diamond or gem that comes with a GIA certificate has been analyzed by an unbiased gemologist. The GIA certificate assures the buyer that the stone is certified by an institute that upholds the highest standards of science, integrity and professionalism.
