Sapphire Jewellery: A Buyer's Guide
Famed for royal blue but found in almost every colour. Here's how to choose a sapphire and wear it.
Quick answer
Sapphire is the gem variety of corundum in every colour except red (which is ruby). Best known for a rich blue, it also comes in pink, yellow, teal and more ("fancy" sapphires). At 9 on the Mohs scale it's superbly hard, and it's September's birthstone.
Blue and beyond
The classic sapphire is a velvety, medium-to-deep blue — the tone made famous by royal engagement rings. But sapphire's colour range is huge: soft pinks, sunny yellows, minty teals and colour-change stones all exist, so-called "fancy" sapphires. This variety, plus its durability, makes sapphire one of the most versatile coloured gemstones for jewellery.
Hardness and treatments
At 9 on the Mohs scale sapphire is extremely hard and ideal for everyday rings. As with ruby, most sapphires are heat-treated to improve colour — a standard, stable and accepted practice — and we disclose any treatment on a stone. Untreated stones of fine colour exist but cost considerably more.
Care and setting
Sapphire's hardness makes it low-maintenance: warm soapy water and a soft brush are all it needs. Blue sapphire looks timeless set with diamonds in white gold; warmer fancy colours suit yellow gold. Every piece is made to your specification in solid gold — never plated — with diamonds independently graded.
Choosing a sapphire piece
Because every piece is made to order in your size and carat, you can keep the design you love and adjust the details to suit. Message our team on WhatsApp and we'll help you choose.
