FAQ - it’s not my size? Can you size it for me? How much will that cost? Is it still returnable?
SIZING ✅ Sizing, we size any gold or platinum ring for free, just add a note in the notes box at checkout letting us know what size you need and we will do that prior to sending so you can try it at home, in your size and make sure it’s the one for you.
Sizing does add around a week to delivery times, and your ring would still be returnable for a full refund.
Silver rings are in stock in various sizes or made to measure 💫 #

What are people dreaming about at the moment ring wise? What trends are we seeing in the trade in mid 2026?…
There are two distinct camps at the moment in the ring world, either lab diamonds, or natural gemstones, surrounded by natural diamonds. People who want full diamond are going lab, the savings are huge, and people who want naturals are going for colour.
Why? Because it’s very hard to spend 10x more on something that looks and behaves the same. If you’ve got a 3k lab ring or a 30k natural, they look the same, and it’s easy to see why people are going for the lab version.
And also understandable that people who want naturals are going for rare natural colourful gems. That look very obviously natural. Six grand on a natural diamond doesn’t get you that far, or cover much of the finger. Six grand on a lab or colourful natural gemstone fills the finger!! ✨🙌
Head over to the website to see the full collection, and bags something dreamy!! 🥰

Did this quick video for a client, just to show how sparkly moissys are 😍
So they’re sparkly… but how sparkly compared to a diamond? They are doubly refractive, which means in real term that they show double the amount of rainbows to diamonds, and that’s what makes them light up a room ✨
Ok, they’re sparkly? But will they last?
Yes. They’re 9.25 on the mohs scale, which means they’re harder than sapphires, they won’t scratch, they won’t dull, this is how they’ll look year in year out making them an amazing choice if you want something dazzling and durable. 💪

Ceylon Sapphire and Natural Diamond Halo Ring.
Some rings are so perfect they almost defy description and this is one of them. It’s basic, there is no gilding of the Lily, an oval sapphire, claw set in Platinum, surrounded by twelve diamonds. Twelve diamonds in a halo works somehow, numbers on a clock, months in a year, it just feels right.
This is an exercise in restraint, using the very best things on the planet, in the simplest way possible and letting their raw natural beauty shine.
This ring is at the very height of quality, and it’s generous too, the stones are big, but not too big for everyday, this would make the most glorious engagement ring, or a fabulous right hand ring. The ingredients are quality with a capital Q. This ring is a timeless Masterpiece. 👑💙✨

✨ This Pink Tourmaline is absolutely beautiful. It’s the nicest elegant n**e blush pink colour, in different lights, the colour changes slightly, and it’s an elegant shape on the finger too, the halo is unusual with the mix of cuts of Natural Diamonds. If you want pink, but want it to be chic, this is possibly your ring 💖✨
