My fiancé purchased my engagement ring from Ken at Ocean State Diamond Co and I couldn’t be happier with my ring. It’s so beautifully crafted and you can tell there was a lot of attention to detail when custom-making it. It’s everything I could’ve wanted in a ring and more. Ken is super kind and welcoming and is very helpful with answering questions. He explained everything I needed to know about my ring in full detail and I left the store feeling more confident in how to take care of my ring and happier than ever! I highly recommend going to see Ocean State Diamond Co if you’re looking for a well crafted and timeless ring or really any piece of jewelry. I will absolutely be coming back to get my wedding band from them as well!

Had an EXCELLENT experience shopping for an engagement ring for my girlfriend with help from Ken and Anthony today. Not only were they professional and knowledgeable, but they were so kind in explaining everything to me. They were incredibly helpful in comparing the different stones- letting me use their jeweler's loupes to actually visualize the differences between them. I am so glad to have come by their shop, and I certainly recommend their expertise to anyone looking for a professional, personable, and kind experience in ring shopping.

I came in to look at this jewelry store. Very nice selection. It looks small on the outside, but bigger in the inside than I thought. Jewelry is a Car (1) The silver chain is a Mazda CX-5_ Its a new car I had for more than a month_ I've been driving it_ The outside of the car didn't look dirty_ Or so I thought_ (2) Anthony is the car wash_ From the trunk to the hood_ He washed the exterior clean_ He didn't look in the inside of my car_ (3) The interior wasn't as dirty as the outisde_ The outside body only had to be scrubbed_ My car looked shiny like sunlight reflecting off the water_ (4) If I'm unable to clean my cars_ If I dont have time to clean my vehicles_ I can drive them here to get them washed_ Can't wait to see the store add more products for future display, and on their website. I will be back again in the future.

My experience with Ocean State Diamond was one of a kind, and an experience I’ll never forget. From the first day, coming in with 0 expectations, Anthony and Ken blew us away with their knowledge of the industry, along with their hospitality. It felt like family taking a look at engagement rings rather than a transactional exchange. The knowledge we got throughout this process was incredible and helped us settle on the ring of our dreams. I couldn’t recommend a business to get all of your jewelry needs more, Anthony and Ken are forever going to be associated with the greatest moment of my life, because they were the ones who put us on the path!!
