If you spend any time researching diamonds – whether you are considering buying, selling, or pawning diamonds – you will see either “GIA” or “The 4C’s” mentioned. The Gemological Institute of America, or GIA, created the 4C scale to establish the clarity and color standards in the diamond and gemstone industry.
While there are other institutions that certify diamonds, GIA is called the “foremost authority on diamonds” for a reason. GIA will grade your diamond, based on the 4C’s, and then offer a certificate that contains all the characteristics of your stone.
While a GIA certificate is not required to buy, sell, or pawn a diamond or colored stone, it serves as unquestionable proof of a diamonds cut, clarity and color, and establishes a colored gemstones’ origins and treatments. GIA is extremely strict in its grading standards, and is known throughout the diamond industry as the most unbiased and accurate opinion when it comes to grading stones.
New York Loan Company truly encourages its clients to obtain a GIA grading report to achieve the highest possible value for their precious stones.
In order to acquire a GIA certificate, one would have to either send in their diamond or gemstone by mail, or walk into a GIA Laboratory and hand deliver a stone. The prices vary, and it would be best to consult their website or call. GIA has locations all over the world, and two in the United States; their primary headquarters in Carlsbad California and one in New York City.
As of March 10th, 2014, GIA will be located on the floors above New York Loan Company, in the International Gem Tower. GIA and New York Loan Company are located in the heart of the Diamond District, on 47th Street between 5th and 6th Avenues in Midtown Manhattan.
