Certificate of Authenticity

We exclusively source natural jadeite jade from Guatemala and Burma (Myanmar) the world’s most renowned origin for fine jade, and natural nephrite jade from Hetian.

We guarantee that our jadeite and nephrite products are:

• Genuine and authentic

For products over $500AUD, each item is accompanied by our in-house Certificate of Authenticity, detailing its individual specifications. For items under $500AUD, a Certificate of Authenticity remains available upon request for an additional $55AUD.

For additional assurance, independent certification from a reputable Australian gemmological laboratory can be arranged for any piece at your request for an additional cost.

Shop with complete confidence. We stand behind every piece with a lifetime guarantee of natural, untreated jadeite and nephrite.

If, at any time, a reputable gemmological laboratory determines that your items are not natural jadeite, natural nephrite or has undergone treatment, we will:

Unlike most jade retailers, we are run by a qualified gemmologist who is a Fellow of the Gemmological Association of Australia (GAA), with deep expertise in jade origin, identification, and treatment detection.

This professional foundation ensures that every piece we offer has been rigorously examined using industry knowledge and standards—so you can buy with certainty, not myths or guesswork.
