Worked with Ken on getting a watch repaired that's over 20 years old. Ken's knowledgeable, professional, and has given the store an inviting atmosphere. Definitely will be going back.

Anthony and Ken were absolute rockstars. Helped me customize my wedding band so I could get it just right and still within my price range. A lot of other stores were basically just middlemen who wanted to sell me off-the-shelf rings and wouldn’t really work with me on customizing. But not these guys. They went the extra mile to make sure I was happy with my wedding band, which is so important for something you plan to wear for the rest of your life, and they understand that.

Got to meet one of the owners at our venue for our tasting and the other at an appointment to pick out my wedding band at the shop, and can't say enough about how kind these guys are. Both owners are super knowledgeable and down to earth. They are very patient and help you figure out exactly what you like. I love that they give you all the information and never try to sell you on things you dont want or need. Highly recommend for both the final product and the experience!

Had a wonderful experience with Ocean State Diamond Co! Was recommended by my soon to be sister in law for their custom rings as I had a specific gem my fiancé wanted, and it turned out marvelous. They walked me through the process every step of the way, showing me 3d modeled previews, laid out multiple options, and accommodated my requests. In the end, I got a great deal and couldn’t be happier with my experience. I would absolutely seek out their services again in the future.

Cannot recommend the guys at Ocean State Diamond Co enough. They made the process so easy, helped me create my fiancé’s dream ring, and we couldn’t be more happy with the result. Will definitely be back!

If you are shopping for wedding bands, engagement rings, or other jewelry, look no further than Ocean State Diamond Co. The experience my fiancé and I had here was absolutely incredible. From the moment we walked in, the hospitality and service were top-tier. We were offered drinks and instantly treated like family, which brought such a wonderful sense of calm and familiarity to the whole process. We didn’t feel like just another customer here; they make you feel like they are genuinely invested in your special day. They are an absolute joy to work with and have easily become my one and only jewelry store moving forward. I will steer anyone in the market for jewelry exactly their way. Honestly, if you ever see a negative review pop up about this place, be wary of it—our experience was nothing short of perfection. Highly recommend!
