GIA & IGI Certification

All tanzanites advertised above are already certified by either GIA or IGI, and the relevant report is included with the stone.

We can also arrange for any other tanzanite purchased from TanzaniteDirect to be submitted for independent certification:

• GIA report: approximately US$290 — allow 3–4 weeks
• IGI report: approximately US$120 — allow around 10 - 18 days

Please email us if you would like this done prior to purchase.
