Because a stone that’s as strong as a diamond and as rare as your story deserves its moment in the spotlight.
The modern heirloom for those that colour outside the lines.
Move over emeralds — there’s a new green gem catching the light (and stealing hearts). Green sapphire is nature’s underrated powerhouse: a variety of corundum coloured by tiny traces of iron or titanium, giving it a glow that shifts from minty-fresh to moody forest, sometimes with electric flashes of blue or gold. Basically, it’s giving main character energy. And with a 9 on the Mohs scale — just one shy of diamond — she’s more than tough enough for everyday love stories, messy adventures, and whatever magic you’ve got planned next.
At Stone Hearts Club, we're not just about the pretty gems - we're about the feeling, the healing, the energy you carry with you. Our customers don't just choose a stone; they choose what it stands for.
Green sapphires are loved not just for their beauty, but for what they bring into your life. They are believed to:
Wear one as a talisman for a steady heart and a clear mind.

Use warm water with a mild soap, gently clean with a soft brush, then leave to air-dry.
When not wearing your green sapphire piece, store in a pouch on its own to avoid scratches from harder materials.
As with all demi-fine and fine jewellery pieces, we recommend a professional check-up once a year to keep the prongs tight and your stone in place.
01. Is a green sapphire suitable for an engagement ring?
Absolutely! It's Mohs 9/10 rating means it handles daily knocks with grace.
02. Will a green sapphire fade?
No - unlike some gems, a green sapphire's colour is stable under normal wear and light.
03. Is a green sapphire more ethical than a diamond?
While every source is different, many green sapphires come from transparent, small-scale mines in Australia, Madagascar and Sri Lanka — making it easier to trace ethical and fair trade practices. At Stone Hearts Club, we only partner with designers who meet our high standards for responsible sourcing and integrity at every step.
04. How do I style a green sapphire wedding stack?
Pair with slim diamond contour bands to let your green sapphire own centre stage. Unusual cuts like baguettes and pears add sculptural elegance, highlighting the gem's unique charm.
For a tonal stack, look to teal tourmalines, soft aquamarines and tanzanites to draw out the green sapphire's dreamy blue undertones.
