Ruby - Loose

Rubies are the red variety of corundum — the same mineral species as sapphire, coloured by chromium and rated 9 on the Mohs scale, among the hardest gemstones in everyday wear. Unlike our sapphires, we do not mine rubies: they are hand-selected in Ceylon and beyond by our FGAA gemmologist, through relationships three generations in the Sri Lankan gem fields have built. Most rubies on the market are heated to improve colour. We hold both heated and unheated stones, and we tell you which is which.

“Went to their website & made an appointment… Sasha took me through the steps and fine tuned the design with a video call. 2 weeks later got the ring delivered. Prices are amazing and what a lovely team. Highly recommend!”
