Are Lab Created Gemstones Different to Naturally Occurring Gemstones?

The lab created sapphires, emeralds, rubies and other gemstones grown at Chatham (including marvellous opals and diamonds) are 100% identical to naturally occurring gemstones. The lab process is a replica of what happens underground to form natural gemstones.

The pressurising process and chemical composition is exactly the same. Lab created emeralds, for example, are made from the same mineral as naturally occurring emeralds: beryl. A hint of chromium is what gives that luxurious green depth, but of course in natural environments the amount of chromium available will vary drastically. For lab created emeralds, Chatham control how much chromium is used to an incredibly exact degree, creating unbeatable green shades in just 12 months.

Using precise pressures and lab conditions, Chatham can create precious gemstones that are chemically and physically identical to those that are produced naturally by the earth in an ethical, sustainable way.
