Every year for her birthday and our anniversary, I renew my promise to my partner. This year I chose The Promise Co. and I couldn’t be happier with my choice. She absolutely adores it and it fit wonderfully.
This is actually my second promise ring from The Promise Co, my boyfriend bought me the cluster one last year, and this year he added to my stack with the pear cut. It’s stunning. The gold is amazing quality and hasn’t worn at all, even after a year of daily wear. They look so perfect together I’m obsessed.
I bought this as my “travel ring” to keep my real engagement ring safe but I think I prefer this one (hope my husband isn’t reading this 😂) The sparkle is unreal and the stack makes it look so much more expensive than it is. I’ve worn it on every trip since and get compliments constantly - no one ever believes it’s not my "real" ring!!
I purchased the beautiful cluster ring in silver. The ring came beautifully presented with a promise card, love the ‘promise’ aspect of this brand. Excellent customer service, quick delivery & a beautiful ring, highly recommend ✨
I've been looking for the perfect rings for a long time, and when I found The Promise Ring Co I was over the moon. I got this ring as my wedding band for my wedding day and paired it with the Promise Oval Ring and it's everything I've ever dreamed of. It’s so incredibly beautiful and I couldn't be happier with it. Thank you so much for making my dream come true 🥺❤️
I got this ring as a 21st present to myself and to promise myself life still goes on and to continue to make myself proud after a couple of hard years and it’s absolutely beautiful. Means the world to me xx
This is my third ring from the Promise Co and it is GORGEOUS. It sparkles so well and I love wearing it alone or with another ring. I need the gold version next but it is a stunner!
The ring is just beautiful! Charlotte went above and beyond to make sure I got exactly what I wanted, and fit me perfectly. The quality is incredible and so affordable! Will definitely be purchasing many more rings from this amazing company, Thank you!!
Absolutely obsessed with my promise ring it’s so beautiful, it came so fast and they messaged me straight away to sort out sizes! Can’t thank you enough 🩷🩷
I received my promise ring today and I couldn’t be happier, the ring is absolutely beautiful & the customer service was brilliant, so friendly and helpful, thank you The Promise Co, you’ve made my day!!!!
5 Stars
I bought this when I broke up with my partner as a promise to myself and I absolutely love the ring and the message behind the brand, thanks Charlotte for all your help with sizing
My boyfriend surprised me with this ring on a lil date we went on. I’m in love with it!
My husband to be bought me this ring as my eternity ring to fit along side my engagement ring also purchased from this company & it’s absolutely stunning !
It compliments my ring perfectly , the sparkle is insane & the quality of the ring is just amazing.
Highly recommended this company their customer service is quick & friendly also.
This is the most perfect ring- I love it stacked with my other rings and just worn by itself. It’s so sparkly, pictures honestly cannot do it justice, I get compliments every time I wear it out. Quality is amazing, really weighty ring and still looks as perfect as the day I bought it.
The most elegant comfortable ring to wear! I’ve been getting comments nonstop about it!!
Cannot put into words how much i love this ring!! The details are incredible xxx
My daughters bought me this Promise Ring for my 50th birthday. I absolutely love it, from the packaging to the ring itself. I’ve had so many compliments on it already, I love wearing it, and they are such good value. They look far more expensive than they are and the designs are so classy. What a brilliant concept!!
Just received my silver cluster ring and I am not disappointed! It is so sparkly and feels such good quality, I would definitely buy from the promise ring again.
You never expect a ring to be as good as the pictures but this is and more. It really is beautiful and looks stunning next to my engagement ring
Absolutely in love with my ring!! So perfect!!
I like the ring but one of the diamonds fell out recently 😔
Beautiful ring . Will definitely be ordering more. Arrived in beautiful soft blue packaging.
