Authenticity Guarantee
Every stone we sell is independently verified, fully documented, and backed by our return policy. This is the foundation on which Shub International has operated since 2009.
Every stone in our collection carries an independent laboratory report from GIA, GRS, AIGS, or Gübelin. No stone ships without documentation. The certificate accompanies the stone — always.
If your stone does not match its certificate or our description in any way, return it within 14 days of receipt for a full refund. No questions asked. Return shipping is covered by us on authenticity disputes.
Tanzanite sourced directly from the Merelani Hills, Tanzania. Colombian emeralds traced to Muzo and Chivor mines. We maintain documentation on mine-to-market provenance for all natural gemstones.
All shipments are fully insured for declared value, shipped via tracked courier (FedEx or DHL), and packed in tamper-evident packaging. Customs documentation is prepared to the correct valuation.
Our Verification Process
We acquire stones directly from miners and rough dealers with verified origin documentation.
Every stone is submitted to an independent laboratory (GIA, GRS, AIGS, or Gübelin) before entering our inventory.
A full grading report is issued, noting weight, shape, colour, clarity, treatment disclosure, and origin where applicable.
Stone details are cross-checked against the certificate before being listed on our website or trade inventory.
Stone and original certificate ship together in tamper-evident packaging with full insurance cover.
Independent Verification Available
Every certificate we issue can be independently verified directly with the issuing laboratory using the report number on the document. We encourage buyers to do this.
If you believe a stone you purchased from us does not match its certificate, contact us immediately at shubinternational@gmail.com. We will arrange collection and a full refund within 5 business days.
Every stone on our website carries independent certification and is backed by this guarantee.
