What Group Taché does

Group Taché is a privately held, family-owned Antwerp-based diamantaire founded in 1957 by Jacques Taché, operating across the natural rough and polished diamond value chain from sourcing through manufacturing, certification, bespoke cutting and after-sales service. The group supplies melee, certified and exceptional polished diamonds to premier luxury maisons and high-jewellery houses, with publicly documented flagship projects for Van Cleef & Arpels (Lesotho Legend, 910ct rough) and Chopard (Queen of Kalahari, 342ct Type IIa from Karowe; Rose of Caroline/Rose of Kao). Its service proposition extends beyond commodity supply into tailor-made solutions — custom manufacturing, recutting, consignment workflows and just-in-time delivery — supported by proprietary in-house R&D including a Naturality Checking machine (claimed unique in individually identifying stone types without sampling) and a Fluting Machine reported to be 10x more accurate and 5x faster than manual methods.

The business operates through a multi-entity legal structure — Taché Company NV (Belgium, holding entity), Taché France SAS (atelier and EU sales), Taché Diamonds Botswana (beneficiation factory), Taché-Uncut BV (Netherlands) and Taché Securities BV (consignment title holder) — with manufacturing or office presence in Antwerp, Johannesburg, Botswana, Armenia, Russia, Malaysia, France and Switzerland. Revenue is generated through one-off diamond sales (melee, certified, exceptional stones), manufacturing and recutting fees, bespoke atelier commissions and consignment/trading transactions under entity-specific sales conditions (Belgian, English, French, Italian, Swiss). Distribution combines direct B2B account management with luxury brands and a gated online inventory portal (sales.groupetache.com) requiring email-verified registration.

The group positions itself as a sustainability-credentialled supplier, holding RJC certification across Belgium, France and Botswana entities, adhering to the Kimberley Process and World Diamond Council System of Warranties, holding De Beers Sightholder status (since the 1970s), and being a signatory to the UN Global Compact, WEPS and Watch & Jewellery Initiative 2030. ESG infrastructure includes the 2021-launched Taché Foundation and the Track 2 Impact reporting system, with Scope 1–2 carbon footprint tracked annually and Scope 3 measured for the first time in 2024.

This represents a flagship collaboration demonstrating Taché's exceptional diamond handling capabilities.

Also collaborated on the Rose of Kao pink diamond project (10.88ct polished from 29.59ct rough), sold to Chopard as the 'Rose of Caroline'. Both collaborations promoted Botswana-origin diamonds to the world.
