Promise Marquise Ring
Hand Set Stones
Anti-Tarnish Coating
Lifetime Sparkle
5 Year Warranty

The Promise Marquise Ring features a hand-set 3.8ct marquise-cut centre stone, designed to create a bold, elongated sparkle while still feeling elegant and refined.
The four-prong setting holds the stone securely while lifting it slightly from the band, allowing light to catch the cut from every angle. The slim band keeps the look balanced, letting the marquise stone remain the focus without feeling too heavy on the finger.
Its tapered shape helps create a flattering, lengthening effect, making it a beautiful choice for those who love statement solitaire rings with a softer, more romantic finish.
Available in 18ct gold vermeil or rhodium-plated sterling silver, the Promise Marquise Ring is finished with a water-resistant, anti-tarnish e-coating for lasting shine.
Perfect as a promise ring, meaningful gift, or alternative engagement-style ring, this design brings together standout sparkle and everyday wearability. Explore more styles in our marquise promise rings collection.

absolutely gorgeous I love it, fits perfectly. Will definitely be buying more 🫶🏼
I got proposed to with this ring last Friday and I couldn't love it any more. As soon as I found the brand I knew I wanted a Promise ring co ring as my engagement ring and seeing it in person its even better than I expected
I purchased this promise ring for someone who means a lot to me, so I wanted something that felt just as meaningful as the promise behind it. When it arrived, it was even more beautiful in person and ended up being perfect for the moment I had planned. She absolutely loved it, and seeing her reaction made the purchase worth it. It’s more than just a piece of jewelry for us, it represents growth, intention, and a promise that means a lot to me. I’m really happy I chose this ring. ❤️
I orderd the marquise promise ring for my girlfriend and it’s stunning. The shipping was fast and I just really liked the way everything went. I would definitely buy more in the future!
Promise Marquise Ring
It was very pretty, and she loved it
My boyfriend proposed with this ring and I’ve had so many compliments on it already ! It’s absolutely beautiful. If your partner wants something that is beyond words, incredibly sparkly, beautifully made and classy I would highly recommend this ring or any of the others ! It’s gorgeous and I’m so happy with it
Stunning well crafted ring.

After I got bought a ring that unfortunately didn’t fit and wasn’t easily resizable, the team couldn’t of done enough to help me, to try and make the best out of a less than fortunate situation! Thank you so much. Would recommend again and again!
Promise Marquise Ring
Lovely ring which fits true to size ! The customer service was also excellent with very quick responses !
Gorgeous ring super clear stone great price
The ring is beautiful. My partner loves it but unfortunately on arrival the size wasn't quite right (our mistake). Fantastic support and response time from Charlotte and we look forward to the right size being delivered.
I purchased this ring on preorder and received an email from Charlotte asking if I would like my other 2 rings that I had purchased sent with this one when it was released or separately. When the ring arrived i was completely blown away with how stunning the ring is, it has been designed and crafted so beautifully and really is a show stopping ring. Unfortunately due to having weird sized fingers that I struggle to find rings for, the ring did not fit. I contacted Charlotte who again was fantastic and communication was very pleasant as I felt awful about having to return the rings. Thankyou so much for creating such beautiful rings and thankyou even more so for being such a wonderful business.
