Frequently Asked Questions
All natural - mined from the earth. We do not sell laboratory-created rubies as natural stones, and we do not stock synthetic material. Every natural ruby is accompanied by a gemmological certificate.
Yes, though they are a limited part of the collection. Heat treatment is standard across the ruby trade; unheated stones of equivalent colour are rarer and priced higher. Treatment status is stated on every stone.
A trade term for the finest ruby colour — vivid red with a slight blue secondary. It has no strict definition, which is why it is applied more loosely than it should be. We use it sparingly.
Yes. At 9 on the Mohs scale ruby is second only to diamond in hardness, which makes it well suited to rings and pieces worn daily.
The same mineral, differing only in colour saturation. Where red becomes pink is a grading judgement rather than a hard line, and different laboratories draw it differently.
Independent laboratory certification is available for higher-value stones. Every stone is assessed in-house by our gemmologist regardless.
Ruby fluoresces under ultraviolet light, which daylight contains and most indoor lighting does not. That is why a ruby can look noticeably more vivid outdoors — and it is a characteristic of natural ruby rather than a fault.
Our rubies are sourced from Myanmar, Mozambique, Madagascar, Tanzania, and Sri Lanka. Each stone is examined individually before it enters our collection, and origin is documented and disclosed.
Warm soapy water and a soft brush. Ruby handles cleaning better than emerald, but avoid ultrasonic cleaners if the stone has significant fractures.
