Based on Colour, Clarity, Cut and Carat – the standard diamonds evaluating system, formulated by GIA's Richard T. Liddicoat in 1953 - transformed the diamond industry. This system ensures that the true value of a diamond can be measured and communicated in a uniform language, and that diamond customers can ascertain the exact value of their purchase.

As part of the modern, state-of-the-art and ethically conscious Antwerp diamond trading community, Diamond Vault NV is qualified to handle the valuation of large, complex, multi-diamond assignments of all types on a national and international basis. Our team of expert evaluators routinely perform valuation exercises – we offer a number of different valuation reports ranging from individual self-contained reports to portfolio appraisals via an Automated Valuation Model.

To ensure that the buyer is assured of the selling price of his diamonds, we provide a two-way quote for all the diamonds in our stock. We also customise our valuation portfolio as per the client’s specific needs. As a unique service, we deliver valuation reports to our customers with specific and exclusive details unavailable with any other gemstone appraiser. We make and stand by a binding offer to buy on the report itself, and are willing to provide a replacement value of the stone with a guaranteed price for replacement.
