Sapphire engagement rings are timeless, distinctive and steeped in history — famously chosen by royalty and admired the world over. If you are considering a sapphire for that all-important ring, here is everything you need to know, from our in-house gemmologist.
Why choose a sapphire engagement ring?
Beyond their beauty, sapphires are wonderfully practical for everyday wear. They rate 9 on the Mohs hardness scale — second only to diamond — so they stand up to a lifetime of daily wear. A sapphire ring is also more individual than a classic diamond solitaire, and often offers more colour and character for your budget.
Choosing your colour
Blue is the classic choice, from the luminous tones of Ceylon sapphires to the rich blues of Australian sapphires. But sapphires also come in pink, yellow, green, teal and unique parti-colours — so you can choose something truly personal. There is no wrong answer; pick the colour that speaks to you both.
Settings that protect your stone
- Solitaire: classic and elegant, putting the sapphire centre stage.
- Halo: a ring of small diamonds around the sapphire adds sparkle and makes the centre stone look larger.
- Three-stone: a sapphire flanked by two diamonds (or vice versa), rich in symbolism.
- Bezel: the metal wraps the stone's edge, offering excellent protection for active lifestyles.
What to look for in the stone
The same principles apply as with any sapphire: prioritise a colour you love, good clarity and an even, well-proportioned cut. Ask about origin and whether the stone is heated or unheated — details that affect both value and meaning. Every stone we sell is graded in-house by our FGAA-qualified gemmologist, so you know exactly what you are proposing with.
Setting a budget
One of the joys of sapphires is that there is a beautiful option at almost every budget. Decide what matters most — size, colour or origin — and let that guide you. A smaller stone of superb colour often makes a more striking ring than a larger, paler one.
