What are GIA Certified Diamonds and AGS Certified Diamonds?

Loose diamonds (not pre-set in a ring or other setting) that have been certified by GIA (Gemological Institute of America) or AGS (American Gem Society); these are the two most widely regarded and recognized diamond grading labs in the world.

Why Do I Need a Diamond Certificate?

Shopping for certified diamonds allows you to make an informed choice about your diamond selections and to comparison shop among various diamond merchants. You can compare one diamond with a particular weight and quality with other diamonds of similar weight and quality to determine which diamond is the better value — or which merchant has the best prices.

What are IGI certified diamonds?

With more locations around the globe than any other laboratory, IGI (International Gemological Institute) is the world's most trusted name for the expert and impartial grading of diamonds, gemstones and jewelry. IGI is the largest organization of its kind, with operating laboratories & offices in Antwerp, New York, Hong Kong, Mumbai, Bangkok, Tokyo, Dubai, Tel Aviv, Toronto, Los Angeles, Kolkata, New Delhi, Thrissur, Surat, Chennai, Ahmadabad and Hyderabad.
