Ruby Jewellery: A Buyer's Guide
The most prized of red gemstones and July's birthstone. Here's how to choose a ruby and care for it.
Quick answer
Ruby is the red variety of corundum (sapphire is the same mineral in other colours), and July's birthstone. At 9 on the Mohs scale it's exceptionally hard — second only to diamond — making it superb for everyday jewellery. Colour is everything, with a vivid red the most prized.
Colour is everything
A ruby's value rests above all on colour: a vivid, pure red — sometimes called "pigeon's blood" in its top qualities — is the most desirable. Too pink and it crosses into pink sapphire; too dark and it loses life. A strong, even red with good brightness is what to look for. Because ruby is rarer than sapphire in fine qualities, colour drives its appeal more than clarity.
Hardness and treatments
At 9 on the Mohs scale ruby is extremely durable and ideal for rings worn daily. It's standard industry practice for rubies to be heat-treated to improve colour and clarity — a stable, accepted enhancement — and we're transparent about any treatment on a stone. This is normal and expected across fine ruby jewellery.
Care and setting
Ruby's hardness makes care easy: warm soapy water and a soft brush keep it bright, and it stands up to everyday wear better than most coloured stones. It looks classic set with diamonds in white or yellow gold. Every piece is made to your specification in solid gold — never plated — with diamonds independently graded.
