Gem Certification

Gemological Authenticity Certificates

Touchstone certification
Given the stature of Touchstone’s in-house Gemological Department, Touchstone issues its own certification, guaranteeing all gemstones purchased on our industry leading website.

Our Gemological Authenticity / Valuation Certificates can be requested when placing your order -  Information such as gem type, weight, size, shape, colour and clarity is included on the certificate.

If you require any further details on our certification, please contact our friendly customer support department at enquires@touchstonegems.co.za

Independent certification

For total piece of mind,  independent gemological certificates from EGL and GIA South Africa can be obtained at your own cost. The gemstone type will determine which institution supplies the certificate:

 EGL      - European Gemological Laboratory

 GIA      - Gemological Institute of America

If you would prefer a specific laboratory to undertake the certification, just email us at the time you place your order.

Due to our large inventory, we do not certify stones before they are sold. When purchasing a gemstone with an Independent Certificate online, the gemstone must be sent to the laboratory for testing. This takes 5 working days, but be prepared to wait slightly longer during busy periods.

Please note:
If you purchase two or more gemstones in a pair or set, the laboratory will test only one gem from the pair or set.
