Tanzanite
TANZANITE & COLOURED STONES
Discuss the stone, the grade and the documentation you need.
Tanzanite is associated with northern Tanzania. Buyers considering a tanzanite purchase should specify whether they are looking for rough or cut stones, target sizes, colour and clarity expectations, quantity and grading documentation.
Origin and grading
Where relevant, request records that support the stated origin, lawful sale and any treatment or grading claims. Independent appraisal may be appropriate before a transaction is finalised.
Project discussions
If your enquiry concerns mining or a supply partnership rather than individual stones, provide the location, ownership, permits, operating stage and available technical records.
Before proceeding
Descriptions, images and general gemstone information do not verify the identity, origin, treatment, grading or availability of a particular stone or lot.
