At Taché, we are proud to offer the guarantee that our diamonds, no matter how small, are 100% natural and unique. Crafted, tested and engineered by our team of experts, our proprietary technologies leave no room for doubt.
We maintain a flawless record in terms of quality and conformity standards to ensure a spotless order supply.
Traceability Assured
We are continuously investing in a series of systems, procedures and standards to ensure that the journey of every single stone is meticulously traced and accounted for.
As a longstanding Sightholder, Taché buys directly from regulated mines to assure the traceability of all our melee diamonds through in-house manufacturing.
Our manufacturing capabilities further strengthen this process. In Surat, India, our facility of approximately 600 skilled workers specializes in polishing melee diamonds ranging from 0.60 mm to 4.20 mm. In Armenia, our factory focuses on larger melee sizes, manufacturing diamonds from 2.30 mm up to 6.00 mm.
