From start to finish, Robbie made designing our engagement ring such an easy and enjoyable experience with his virtual consultations. He really took the time to listen to what we wanted, sourced the perfect diamond for us, and pulled it all together for our big day. The ring fit perfectly, sparkled beautifully, and made the proposal moment even more magical. We couldn’t be happier and are so excited to have this stunning piece for the rest of our lives!

The Love Story
Austin and Faith met while she was going to bible school on Kauai. Austin has been highly involved in Kauai's Keala foundation, which uses Crossfit to keep the youth of Kauai out of bad habits. He and Faith connected on fitness and their faith, and their relationship blossomed into something beautiful and he reached out to us to help him seal the deal with a ring as unique as his love.

The Ring
Faith wanted something delicate yet meaningful, and this ring delivers on every level. With a hidden halo and two peekaboo birthstones for a personal touch, the design brings together thoughtful details that make it uniquely theirs. It’s a piece that feels effortlessly current yet timeless—one that will look just as breathtaking decades from now. If you’re a fan of classic beauty with a contemporary twist, this ring is everything dreams are made of!

The Symbol
This is one of our most requested designs. A jaw-dropping 2.5-carat oval diamond that’s as close to perfection as you can get. The wispy, airy band is dainty yet built to last. Its timeless oval cut exudes elegance, while its brilliance and clarity make it a showstopper. This diamond isn’t just a gem—it’s the perfect blend of modern sophistication and classic design. If you see them around, make sure to congratulate them and ask to see her ring!

The Review
"The best you can ask for! Amazing service by amazing people. I am beyond impress with the final results. I got to meet with Robbie a couple times over coffee and go over the design I was looking for. He was super accommodating to what we had in mind. I’m so glad I got to do this process with him. Highly recommend."
