REAL STORIES
Trusted by clients across Kauai and beyond
I don’t usually write reviews but I had to make an exception for Robbie. Not only is he incredibly professional, he’s also one of the kindest people I’ve met. His customer service is top notch and he genuinely cares about you, not just the sale.
The ring turned out absolutely amazing and what really blew me away was that he went out of his way, even blocking off his day, to travel and help me out. Everyone who has seen the ring loves it.
Honestly, Robbie is more than just a pro. He’s a truly great human being and has become a great friend. The proposal wouldn’t have been as beautiful or meaningful without him.

Robbie and the Kauai Custom Jewelry team were absolutely amazing to work with!
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!
Kristian Altuve
Choosing Kauai Custom Jewelry to make our wedding bands was one of the best decisions we made during the wedding planning process! Robbie was incredibly helpful and supportive throughout the entire process of creating both my wedding band and my fiancé’s. He listened to exactly what we wanted and brought our vision to life perfectly.
What stood out most was how genuine and patient he was. He never pressured me into anything or tried to upsell me. His guidance felt informative, not salesy, which I really appreciated.
In the end, our rings turned out even better than we imagined. I’d 1000% recommend Kauai Custom Jewelry to anyone, and I’d absolutely work with them again!

Robbie went above and beyond to make sure we got exactly what we wanted. His dedication to the craft and to people’s stories is what makes the difference. Can’t wait to get another ring in the future for anniversaries and special gifts from him.
