Recertification by the RJC
We are pleased to announce an important certification milestone: Burkhardt + Bischoff has been successfully recertified by independent auditor SGS in May 2026 and is now a certified member of the Responsible Jewellery Council (RJC) until May 2029.
New to this certification cycle is our certification under the Laboratory Grown Material Standard (LGMS) – a dedicated RJC standard that ensures responsible practices throughout the entire supply chain for laboratory grown materials. The audit (Certificate No. 0000 7746) covers both our site in Keltern, Germany and our subsidiary Beauty Bijoux Co. Ltd. in Thailand.
