At Taché, we aspire to be our customers’ servicing partner of choice. Our team assists in streamlining the diamond purchasing process, taking the weight off our clients’ administrative workload to leave our customers free to excel at what they do best: creating exquisite jewellery pieces.
The Certified Diamonds Department mainly focuses on providing diamonds for timeless jewellery pieces such as tennis bracelets and eternity rings that never go out of style.
As we manufacture our diamonds in-house, Taché is able to polish gemstones to the exact requested dimensions and symmetry needs while guaranteeing full traceability. For certified diamonds between 0.50 and 2.90 carats, this in-house polishing takes place at our facility in Gaborone, Botswana.
All diamonds in this department are certified exclusively by the Gemological Institute of America (GIA), ensuring global recognition, reliability and traceability.
