The World Diamond Group, a company founded in Vicenza in 1987, born as a diamond importer, then became a creator of high jewelery. The products are guaranteed by a professional certification that safeguards the purchase value over time. The jewels are manufactured without nickel (metal excluded because it is considered carcinogenic by the European Community); moreover, only conflict-free diamonds are set (therefore jewels without bloody diamonds). Diamond Invest supports an ethics on the method of selling its jewelry, which consists in offering the customer a product that comes from skilled labor and without exploitation of any kind. Another ethical reason is the price policy which is absolutely correct in relation to the price quality offered. Reliability distinguishes Diamond Invest in the jewelry world, because it comes from the idea of offering a precious jewel that maintains its value over time.
