“The value of a precious stone is determined by its gemological makeup, natural rarity and finished quality. Diamonds and gemstones of similar appearance can have important differences in value. Gemstones should only change hands when accompanied by a certificate attesting to quality. Regardless of location or marketplace, an authentic Laboratory Report is the common language of trust and confidence in the gemological world, and should be considered an essential part of any transaction.” – International Gemological Institute
