Our read on TCI

5 of TCI's 6 graded samples passed (83%), and 100% of all samples were sent in by buyers rather than by the shop.

When a sample failed, the most common reason was purity under 99.5% (1 time).

Against the 302 shops with at least five graded tests, TCI's pass rate is at or above 78% of them, and it has more tests on record than 9% of them.

When and how TCI was tested

Samples per month. The darker part of each bar failed.
