Building an engagement ring with Moshe of Diamond Guy Hawaii was a fantastic experience. Moshe's expertise and guidance made the process smooth and enjoyable. The ring he helped create surpassed all expectations, and my fiancée absolutely loves it. Moshe's attention to detail and personalized service at Diamond Guy Hawaii made our engagement moment truly special. Highly recommend for a seamless and delightful ring-building experience!

Moshe was responsive, easy to work with, accommodative, and most importantly creates beautiful jewelry. Was taken advantage of a bit on price

I was introduced to Moshe, Erin and his amazing team by a close friend a couple months ago. I am beyond grateful to have met these exceptional people. From the moment I walked in I was treated like family. All I had was couple pictures on my phone of rings that my girlfriend liked. Moshe and his team showed me many different examples of how they could design the same ring. I was soo impressed!! The meticulous art and craft of making the ring is incredible! Especially the amount expert knowledge you have to have. I had a short timeline for when I was thinking about proposing. Due to my girlfriend being a full time student and not having many breaks in her schedule. Moshe and Erin reassured me they could make it happen! Once the ring was ready, I planned a last min 2 day trip and hopped over to Kauai. With the help of my friends I proposed at Queens bath. The ring is absolutely incredible!!! Definitely one of the best days of my life and my fiancés reaction was priceless. From start to finish Moshe, Erin and the team exceeded all expectations!! They’re family I couldn’t be happier. Mahalo nui loa Spencer aka “Matt”

A great bespoke jeweler! My fiancee wanted a very particular kind of engagement ring. We ordered a sapphire from Sri Lanka, and worked with the Diamond Guy to come up with a design based on my fiancee's tastes. I was nervous to make such a big purchase without know the final product. It turned out better than me or my fiancee ever imagined. It is a truly unique and elegant ring that perfectly matches her style. The Diamond guy was very professional and guided us through the whole process. My fiancee is still gushing over the ring weeks later. She says its perfectly her. I would recommend the Diamond Guy to anybody interested in bespoke jewelry.

Moshe’s work is beyond exceptional. Regardless of your budget he works with you to create beautiful pieces based on your vision. My engagement ring was something I immediately fell in love with! My fiancé wanted something unique for his wedding band and Moshe was able to create something upon his request. He is honest, personable, and really makes the whole experience enjoyable and stress free. We are so excited for our wedding, and would not recommend anyone else but Diamond Guy Hawaii for all your wedding needs. Everything is uniquely designed to your individual needs so when you are ready for an appointment, be sure to have ideas to show him what you’d like. He really can do anything!

The Diamond Guy Hawaii was incredible to work with! After traveling to Tahiti last year I brought home a pearl which my fiance had fallen in love with. Knowing she didn't want a traditional diamond engagement ring, Moshe was able to to take our concept and create a stunning pearl engagement ring which we both absolutely love. Their customer service is also second to none. They were able to work within my tight schedule, and were flexible when things inevitably came up. I am so glad I put my trust in Moshe and his team, and am excited to work with him on our wedding bands!!

She said Yes! Highly recommended professional jeweler, staff, and customer service. Moshe and his team ensured a smooth and worry free engagement ring purchasing experience. My fiancé is very active and I needed a ring that could endure her lifestyle. The Kukio Signature setting was the perfect match. Moshe customized the profile and the result was truly breathtaking. The proposal was a complete surprise and the initial ring size a little small. DGH adjusted the ring immediately and she was ready to see the family. Many Mahalos to Moshe and the Diamond Guy Hawaii O'hana.
