The classic diamond solitaire will always have its place — but in 2026, more couples than ever are saying "I do" to colour. Nearly 40% of engagement ring buyers now choose a coloured gemstone over a traditional diamond, drawn to stones with personality, meaning and individuality. Here is our in-house gemmologist's guide to the trend, and how to choose the perfect coloured stone.
Why coloured gemstone engagement rings are booming
- Individuality: a coloured stone lets you express your personality and choose something truly your own — no two are alike.
- Meaning: many couples pick a colour with personal significance, from a birthstone to a favourite hue.
- Value: a beautiful coloured gemstone often delivers more colour, size and character for your budget than a diamond of the same price.
- Durability: the most popular choices — like sapphire — are hard-wearing enough for a lifetime of daily wear.
The most popular coloured stones for engagement rings
Sapphires lead the way — and not just classic blue. Explore luminous Ceylon sapphires, characterful Australian sapphires, and the trending teal, parti and rare padparadscha varieties. At a durable 9 on the Mohs scale (second only to diamond), sapphire is ideal for everyday wear.
Opals offer something completely different — a mesmerising play-of-colour unlike any other gem. They suit special-occasion rings and protective settings beautifully; browse our opals to see their magic.
How to choose a coloured gemstone engagement ring
Start with the colour you both love — there is no wrong answer. Then consider durability (sapphire is superb for daily wear), the setting (a protective style suits softer stones like opal), and, above all, buy from someone who can verify exactly what you are getting. Every stone we sell is graded in-house by our FGAA-qualified gemmologist, with colour, origin and treatment disclosed up front. For sapphire specifics, see our sapphire engagement ring guide.
