Certification

A certificate of Authenticity is issued by a local Gemologist, Nan Yang Gemological Institute (NGI), a certified gemologist of GIA (Gemologist Institute of America). At One's Treasure Jewellery, our gemstones are tested and certified by gemologists to ensure they meet the quality expectations. Certification is an assurance and an offer of confidence we would love to give to our customers regarding the values of our stones. 

One's Treasure Jewellery will provide the certificates upon request for rare and high value stones once purchase is made. You can request for the certificates with additional charges. The charges will be at our discretion cost depending on the collection.
