Your Love Stories

"She makes a true one of a kind engagement that grabs everyone's attention. Kristin is worth every star and 100 times more. She has great customer service, she is helpful and she worked with my timeline. There is nothing she can't do. She is worth every dollar and guys if you get an engagement ring from her. I promise the only words out of your partners mouth when you hit a knee will be yes."

"There are not enough words to describe how special it feels to receive a piece of Kristin's amazing work of art. I absolutely love having such a unique ring and receive endless compliments on its beauty. I never attempted to seek an ethically sourced ring, but now that I have a moissanite stone, recycled gold band and diamonds that come from fair humanitarian practices- I feel so proud. Kristin makes you feel like an old friend- not an experience you can get with all jewelers, especially one from across the country!"

"If I could give Kristin a million stars, I would. She is INCREDIBLE!! ...Honestly, I got more compliments on the ring than our actual engagement!! But seriously, she makes the process of finding a ring & your size SO EASY. I was actually talking directly with her throughout the process, which is unheard of anywhere else. If you want a unique, one of a kind ring that is insanely stunning while supporting a female owned small business, then Kristin is your girl."

"I have been pretty speechless since receiving the ring from Kristin Coffin! From quality to customer service, it has been an amazing experience. Not to mention, the ring is absolutely more than I could have ever imagined. It is so stunning and I cannot wait to give it to my future wife! Definitely recommend this to anyone searching."

"Kristin is so pleasant to work with. Her communication is very responsive and she takes the initiative to make your experience easy and memorable. Her work impeccable and are even more gorgeous in person! I highly recommend Kristin Coffin Jewelry!"


Sustainability & high-quality craftsmanship are at the heart of what we do. Every gemstone is hand-selected and each ring thoughtfully designed for a new era of ethical keepsakes.
