Moonstone and diamond engagement ring

Finding the perfect engagement ring is a minefield in itself, and one of the biggest decisions when choosing the one is which route to go down. A moonstone engagement ring is said to represent new beginnings, making them perfect for a romantic proposal! Moonstones are also said to boost positivity and compassion, meaning they’re a truly lovely choice.

The really great thing about moonstone engagement rings is that they’re just that little bit different and if you’re a less traditional bride or groom, a moonstone may offer an alternative route to go down. Worlds away from a classic, traditional cut diamond, the moonstone is quirky, fun, and outside the box. But that doesn't mean you can't incorporate diamonds into your special accessory - our edit includes lots of moonstone and diamond engagement rings too.

Better yet, the stone is often fairly affordable, meaning they’re an amazing option if affordability is a key requirement. From oval moonstone engagement rings to eternity styles and picks that would work as a moonstone wedding ring, we’ve picked out some of the most beautiful moonstone engagement rings to suit all sorts of tastes and budgets.

Are Moonstones Good For Engagement Rings?

Marking your engagement with a moonstone ring is a lovely idea and not just because they are a much more affordable option than diamonds! Carrie Elizabeth Jewellery features lots of pieces with this beautiful gemstone. 

Founder and designer behind the brand Carrie Dennahy says: "Moonstone is a symbol of new beginnings making it the perfect stone for an engagement ring! It is known to bring calm, peace and tranquillity to your everyday life. Moonstone shines a beautiful iridescent pink/blue hue in the light making it both eye catching and easy to wear". 

Is Moonstone Durable Enough For an Engagement Ring?

As an engagement ring is likely to be worn everyday, you'll need to ensure it features a gemstone that is hardy and won't wear. "Moonstone isn't as durable as a diamond but still measures 6.5 on the Mohs scale and so when treated with love and care it will still last a lifetime," Carrie explains.
