What Our Customers are saying
Decided to stop by the diamond district right before my flight as I needed to buy a wedding band. Sea wave was a fantastic experience with wi detail customer service. I got a better band for a better price than I would’ve had I purchased in Denver. Super happy with my purchase and now I’ll wear a piece of NY forever.

I have had an exceptional experience with Sea Wave Diamonds every single time I visit. As a repeat customer, I can confidently say their service, craftsmanship, and attention to detail are unmatched. I always go back to them for all my jewelry needs because they consistently deliver quality and care beyond expectations.

I’ve been coming to this jewelry store in the Diamond District for about three years now, ever since I received my engagement ring from my husband, which was originally purchased here. The quality of their pieces is outstanding, and the service is just as impressive. Every time I stop by, they clean my ring and make it look brand new again—always with a smile and absolutely no hassle.

We brought a Pinterest board and a budget—left with a custom oval solitaire that looks twice the price. Clear timelines, GIA paperwork, and painless resizing.

Good experience selling a watch and resetting my diamond ring. I talked, texted and emailed with Xenon, came to an agreement and he sent me a FedEx label via email. I live in Ohio and sent them my ring and white gold Rolex watch via prepaid/fully insured FedEx. I received payment via bank transfer and they sent me my reset ring a couple weeks later. Overall, I am satisfied with my first experience dealing with Sea Wave Diamonds and would not hesitate to do business again with them.
