All of our jade jewelry is crafted from natural, authentic jadeite and nephrite jade of the highest quality. Our jadeite raw material comes from Myanmar (formerly Burma), which supplies over 95% of the jadeite available on the market. Nephrite jade is primarily sourced from British Columbia, the world’s largest producer and exporter of nephrite. The carving, polishing, and treatment of our jewelry are performed in our factories located in East Asia. Read more here! We also offer NGTC certification upon request, though additional fees will apply. The National Gemstone Testing Center (NGTC), part of the Gems & Jewelry Administrative Center of MNR of P.R. China, is the world’s leading gemological laboratory and the highest authority for certifying jade gemstones, comparable to the GIA for diamonds in the United States. NGTC certifications are recognized internationally by ILAC-MRA and CNAS, and nationally by CMA. You might wonder why jade is often associated with China. The answer is that China is the largest consumer of jadeite and nephrite. However, China does not produce jadeite, as the geological conditions required for its formation are not present there.
