Chatham Lab Created Rubies, Emeralds and Sapphires – Coming Soon

Chatham, the world-leading laboratory grown gemstone jeweller, is our newest partner at Lily Arkwright. Soon we’ll be bringing their beautiful lab created emeralds, sapphires, rubies and more to our online collection of exquisite moissanite jewellery.

Chatham grow gemstones from laboratory crystals to create the earth’s finest jewellery pieces. They are renowned for their lab created rubies with rich red shades, emeralds with glowing green facets and intense blue sapphires, among others.

The amazing benefits of lab created rubies and other gemstones include:

  • Bright colours free from imperfections.
  • Gems identical to naturally occurring stones at a better price.
  • Eco-friendly, ethically lab grown gemstones don’t require energy draining digging or dangerous mining.

Chatham has been growing gemstones for 75 years. After decades of refining techniques, they are now producing the world’s best precious gemstones and have donated to many prestigious museums worldwide. You can read more about their long, celebrated history here.


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.
