2 Carat Diamond Tennis Bracelet 750 (18ct) White Gold. Stamp mark K18 (white gold) and 2.00 for the diamonds total weight. Hallmarked by Birmingham Assay office in accordance with UK law and eBay's authentication process. This hallmark has been placed between the K18 and 2.00 stamp (see pic). Please see pics for approximate length and weight. The clasp is secure. On purchasing, I was informed that this is Colour G and Clarity SI1. I do not have a certificate nor GIA certificate to confirm this. The bracelet will come in the bracelet box shown in the photographs, but this isn't the original one. I'll pay the extra for insurance so the bracelet is covered to the correct value during transit.
