Tanzanite Certification

All of our tanzanite, both loose tanzanite, as well as the center stones in our full line of tanzanite rings, is sourced from certified parcels of tanzanite only from registered sightholders of Tanzanite One Ltd. While many of the individual stones do not come with certification (some do!), they are guaranteed to be genuine. If you require hard-copy certification and/or appraisal, we recommend the services of LGLab.com for inexpensive certs. Please view the individual item descriptions to see if that item comes with certification. If so, a picture of the cert will be present.

Labtrade Gemological Laboratory reports provide confidence about the integrity of the jewelry, diamonds, and colored gemstones you purchase. With the (LGL) colored gemstone certificate, appraisal report and authentication report you are assured that each item has passed through their rigorous quality assurance process. Reports for a single stone or ring are available, starting at just $49. Please visit them for additional information. All of our gemstones are guaranteed to be genuine and supersede any return privilege limits. In other words, you have an unconditional guarantee as to the authenticity of your purchase, without exception and not subject to time constraints.

We have sold thousands of tanzanites and tanzanite rings over the past decade and have never had an issue related to the genuineness of our gemstones. You may safely and confidently purchase from us, knowing that you are purchasing genuine gemstones, without the up-front costs of 3rd party certification. Please contact us if you would like eTanzanite to obtain certification on your behalf. Sometimes this is a lengthy process (weeks), however we have found that LG Labs has a fairly quick turnaround.
