Further, all our Gold Jewelry is stamped with .916 (for 22k gold) and .75 (for 18k gold).
Gemological Institute of America (GIA)
Established in 1931, GIA is the world’s foremost authority on diamonds, colored stones, and pearls. A public benefit, nonprofit institute, GIA is the leading source of knowledge, standards, and education in gems and jewelry.
International Gemological Institute (IGI)
IGI was the first lab to develop jewelry identification reports and is the leader in this field today.
Most of the world's diamonds and gemstones are already set into jewelry. IGI's expertise in the analysis and documentation of finished jewelry items is unrivaled anywhere. This work is more complex than the analysis of loose stones.
Without disassembling heirlooms or complex pieces, IGI has developed techniques for providing expert and impartial analysis of a jewelry item's precious stones, total carat weight, color, clarity, natural origin, and details of mounting. Clear documentation and photographs are issued for every item. These standardized photos are extremely useful for consumers, showing details of craftsmanship that may not be visible otherwise.
