DODAQ has launched a demo version of what appears to be the first ever online diamond exchange, enabling professional traders to buy, sell and hold certified polished diamonds like stocks. The company offers a two-way auction for traders and facilitates electronic transactions with real-time tradable pricing. Now, it’s been a while since I’ve traded any diamonds, but according to company management the mechanism is bound to make waves in the industry. The way it works now, is that there’s no real fixed price for polished diamonds. The few inventory lists that give an idea of which stones are out there, are often inaccurate or incomplete. Buyers and sellers pretty much agree on pricing based on a scheme that’s distributed on a weekly basis, but without any real, dynamic transaction data that can be used for benchmarking. DODAQ aims to provide a centralized, global meeting place that enables basically anyone to trade or invest in diamonds, with transparency on rates. The platform also allows outsiders to start investing in diamonds and set up a virtual holding.
