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.

Emeka Ezugwu
Jewellery EnthusiastsI’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.

Jewellery EnthusiastsWe 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.

Jewellery EnthusiastsGood 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.
