Would you wear the exact same dress as every other bride? Probably not – so why settle for a colourless centre stone if vivid hues make your heart race?

From red-carpet proposals to TikTok unboxings, coloured gemstone engagement rings are exploding in 2025. At Commins & Co we’re seeing more brides-to-be choose sapphires, emeralds and modern pastel gems that shout personality as loudly as they sparkle. Below, discover the four gemstones dominating mood boards, how to style each one, and the practical tips that turn a Pinterest crush into an heirloom you’ll adore forever.

1) Royal Sapphire – Forever Iconic

Ever since Princess Diana’s oval sapphire made history (and now graces the Duchess of Cambridge’s hand), deep-blue corundum has been the shortcut to regal romance. Sapphire rates 9 on the Mohs scale, making it second only to diamond for durability—ideal for daily wear.

How to style it

• Metal match: Platinum or white gold intensify sapphire’s cool tones; yellow gold warms them for a vintage vibe.
• Shoulder sparkle: Add a pavé band for star-bath brilliance, or halo it with petite lab-grown diamonds to maximise perceived size without murdering the budget.
• Wedding-ring pairing: A slim diamond-set wedding ring echoes the halo and keeps the focus on that mesmerising blue.

2) Emerald – Green with Envy (in the Best Way)

Emerald’s lush hue symbolises new beginnings—perfect engagement symbolism. It does, however, sit at Mohs 7.5-8, so a protective setting is key.

How to style it

1. • Bezel brilliance: Encasing the girdle in gold shields the stone while creating Art-Deco chic.
   • Yellow-gold magic: Emerald + yellow gold = rich, old-Hollywood glamour that photographs like a dream.
   • Straight-edge band: Because emerald-cut stones feature clean lines, pair yours with a channel-set or plain metal band for architectural harmony.

   3) Morganite – Millennial Pink Romance

   Peachy-pink morganite shot to fame when trend-setting brides wanted blush-toned rings to match rose-gold décor palettes. Its affordability lets you choose a larger carat without sacrificing clarity or hue.

   

   How to style it

   • Rose-gold on rose-gold: The warm metal amplifies morganite’s feminine glow.
   • Double-halo drama: Surround a round morganite with twin halos of petite diamonds—unapologetically extra and oh-so-Instagrammable.
   • Stacking future: Pair with a skinny rose-gold engagement-ring guard for anniversaries; the tonal blend feels effortless.

   4) Aquamarine – Something Blue, Something Cool

   Pale-blue aquamarine offers icy brilliance for brides who adore colour but crave subtlety. With a hardness of 7.5-8, it resists scratching better than most gemstones in its palette range.

2. How to style it

   • Platinum perfection: The white metal makes aquamarine look almost ethereal.
   • Mixed-metal moment: Can’t pick one metal? Combine platinum claws with a yellow-gold band for the on-trend two-tone look.
   • Snow-queen halo: Frame the gem in icy lab-grown diamonds to echo frosted winter scenes—ideal for Christmas proposals.

   Lab Grown or Natural Gemstones?

   Just like diamonds, the most popular gemstones are also available in either lab grown or natural versions. At Commins and Co, we offer both options where possible.

   

   Lab grown gemstones are great for getting colour consistency which can sometimes be an issue with natural gemstones. This inconsistency in natural stones should be considered part of their beauty and their uniqueness is a key feature in why they are popular. However, for anyone concerned about colour variations and imperfections in their gemstone, lab grown versions offer a great alternative.

   Available in a wide range of sizes and shapes, we strive to have the best range available.

   Practical Tips Before You Say “Colour Me Engaged!”

   1. See the stone in daylight – Jewellers’ LEDs can mask or exaggerate tones. Step outside to ensure the hue makes your heart flutter in real life.
   2. Mind matching – If you plan his-and-hers rings, decide whether you’ll echo the gemstone colour in his band via subtle inlay or keep the spotlight solely on yours.
   3. Check toughness – Softer gems aren’t deal-breakers, but they do need bezel settings or halo “buffers.”
   4. Budget smart with lab diamonds – Surround coloured centres with sustainable sparklers to boost wow-factor without inflating price tags.
   5. Plan the stack – A slim contour band leaves room for future anniversary or eternity rings, ensuring your gemstone remains centre stage.
