Coloured-Gemstone Engagement Rings: Sales Up 55%

Coloured-gemstone engagement rings — rings with sapphires, rubies, emeralds, and other coloured stones as the centre stone — are up 55% in UK sales year-on-year, according to data from UK jeweller trade association Houlden published in Q1 2026. The shift has been building since the late 2010s but accelerated sharply in 2023-2026 as the wider trend toward personalisation over tradition gained momentum. Sapphire remains the dominant choice at 38% of coloured stone purchases, driven in part by the continuing cultural presence of Princess Diana’s ring. But the category is broader than sapphire — and the price advantage over diamonds is compelling for many UK buyers.

By Matt Ward, Editor at Weddings Hub. Based on Houlden UK jeweller trade association Q1 2026 data on coloured stone ring sales; Weddings Hub survey of 15 UK jewellers in May 2026; review of 95 coloured stone engagement ring purchases in Weddings Hub directory data January-May 2026.

Sapphire — why it leads every other coloured stone

Sapphire’s dominance in the UK coloured stone market has a specific cultural driver: Princess Diana chose a 12ct Ceylon blue sapphire for her 1981 engagement ring. That ring passed to Princess Kate in 2010 and has generated continuous media coverage and search interest ever since. No other engagement ring has had an equivalent sustained influence on UK buyer preferences over 45 years.

Beyond the royal connection, sapphire has practical advantages:

Hardness. At Mohs 9, sapphire is the second hardest gemstone after diamond. It resists scratching from daily wear better than any other coloured stone. This matters enormously for a ring worn every day for decades.

Colour range. Sapphire comes in blue (most popular), pink, yellow, padparadscha (pink-orange), purple, and white. The “sapphire” name covers all colours of corundum except red — red corundum is ruby. This gives buyers enormous colour flexibility under one stone category.

Availability. Ceylon (Sri Lanka), Madagascar, and Australian sapphires are reliably available in the UK market at accessible prices. Fine Kashmir sapphires are rare and extremely expensive.

Value. A top-quality 1ct Ceylon blue sapphire costs £800-£4,000 — far less than a 1ct diamond at £5,500-£8,000. For buyers who want a large, visually striking ring for less, sapphire delivers.

Ruby — the collector’s choice

Ruby is the red variety of corundum — the same mineral as sapphire, just red. It shares sapphire’s Mohs 9 hardness, making it equally suitable for daily wear.

Fine rubies from Burma (Myanmar) are among the most valuable gemstones in the world — a high-quality 3ct Burma ruby can exceed £500,000 in value, outpacing equivalent diamonds. For most UK buyers, African ruby (Mozambique, Tanzania) and Thai ruby provide beautiful red stones at accessible prices.

UK market reality: a 1ct Mozambique ruby in VS clarity with good red colour costs £1,500-£4,000 in a solitaire setting. The deep red colour — particularly in a yellow gold setting — creates a striking, confident ring.

Ruby carries strong symbolism in many cultures: it represents passion, love, and protection. This makes it a meaningful choice beyond aesthetics.

Emerald — the high-maintenance option worth considering

Emerald is a green variety of beryl. It is softer than sapphire (Mohs 7.5-8) and — more importantly — typically contains inclusions called “jardin” (French for garden) that affect structural integrity. Emeralds chip more easily than sapphires under impact.

For a buyer with an active lifestyle or who works with their hands, emerald carries higher risk of damage than sapphire. For a buyer who is careful with jewellery, emerald is a practical choice.

The emerald colour — particularly deep Colombian green — is extraordinary. Colombian emeralds are the most prized origin; Zambian emeralds offer excellent colour at lower cost.

UK pricing: a 1ct Colombian emerald in a simple solitaire costs £2,000-£8,000 depending on colour and clarity. Zambian equivalents: £600-£2,500. Lab-grown emeralds are available from £200-£400 for a 1ct stone.

Critical note: nearly all commercial emeralds are treated with oil or resin to improve appearance and stability. This is standard practice and not a quality issue. Ask for a certificate confirming the treatment type.

Morganite — the rose gold match

Morganite is a peachy-pink beryl (same family as emerald). It is softer than sapphire (Mohs 7.5-8) but durable enough for regular wear.

The stone’s pink-peach colour pairs exceptionally well with rose gold — the combination has become one of the most copied engagement ring aesthetics of the past five years. The warmth of rose gold enhances morganite’s colour in a way that platinum or white gold does not.

At £400-£1,200 for a 1ct stone, morganite is significantly cheaper than sapphire and ruby. This makes it attractive for buyers who want a substantial stone size at lower cost. A 3ct morganite in a rose gold halo setting can be achieved for £1,500-£2,500 — a ring that reads as visually large and distinctive.

Other stones worth considering

Aquamarine. Blue-green beryl. Mohs 7.5-8. March birthstone. Pale blue-green colour. Elegant, less saturated than sapphire. Good for buyers who want a subtle blue. UK pricing from £400-£1,200 for 1ct.

Alexandrite. Extremely rare chrysoberyl that changes colour from green in daylight to red in incandescent light. One of the rarest and most unusual stones in jewellery. Fine natural alexandrite is extremely expensive (£5,000-£30,000 per carat). Lab-grown alexandrite is available from £200-£500 per carat and shows the same colour-change phenomenon.

Tanzanite. Trichroic blue-violet stone found only in Tanzania. Softer than sapphire (Mohs 6.5-7) — requires care in daily wear. Beautiful colour. Only available in natural form (no lab-grown production). UK pricing from £600-£2,000 for 1ct.

Opal. The most spectacular play-of-colour effect in gemstones. However, opal is soft (Mohs 5.5-6.5) and sensitive to temperature changes, dry conditions, and impact. Not recommended for a daily-wear engagement ring unless the buyer fully understands the care requirements and accepts the higher risk of damage.
