Reviews & Testimonials:

Highly Recommended!

“The guys over at R & S diamond exchange did an excellent job helping my fiancé and I design an engagement ring. They guided us through the process and were honest and just incredibly nice and helpful. The ring came out beautiful. After coming here, we knew we didn’t need to look any further and that we were in great hands.” – Shayna F.

Five Stars!

“These folks are top notch business owners! They were able to help us with some of my mom’s jewelry – removing stones from settings in a ring and hand cleaning another ring. They gave their condolences on my mom’s passing and wouldn’t take a single dollar from us! A true class act. If you want quality products and quality service from local, long-time residents, go here!! You won’t be sorry. Thank you R & S!!!” – Claire A.

Friendly and Honest

“Very friendly and honest jewelers ! I have purchased and sold gold jewelry to watches with R&S and I am always treated like a family friend. Other Jewelry stores I have used in the past to purchase and sell items I was kinda of mis treated and so where customers in front and behind me . I wish I never used some places and only used R&S , they fixed my jewelry and did it right . Don’t be bullied by other Jewelry Shops and told tales , Go to R&S and get quality service, plus I and others love have everyday conversation with their staff , not always business and fun life stories.” – Jon T.

Very Professional

“I  have passed by here many times, but stopped in for the first time yesterday to replace a watch battery.  The gentleman was very friendly and professional and quickly replaced my watched battery.  They have a beautiful collection of cameos and other beautiful pieces.  This is my new go to place for professional and friendly service.  Highly recommended!” – Dan D.

Extremely Helpful

“I had a gemstone that I wanted to sell. I’m new to the area and asked around and R&S was the most common answer I received. Went to them and spoke first to Richard. He examined my gemstone, introduced me to Robert, we discussed, and agreed upon a very fair price. I sold the stone to them. I also had three watch batteries replaced and they did not charge me for them. Richard and Robert were very helpful and patient. Many jewelers just want to sell you something quickly but Richard and Robert took the time to make sure everything was right. I certainly will give them my business again and again. Thanks Guys!” – Alan G.

Excellent Service!

“Excellent service. Family are top notch and do everything they can to make the experience flawless!! I got my Fiancé engagement ring with them. From day one they advised me as to what to look for and what diamonds to stay away from. Very knowledgeable and very honest. I will definitely be buying all our jewelry from Rich and his family!!” – Nicholas R.

Top Quality

“I recently purchased an amazing Necklace for my wife! This is a family owned business and they have always been amazing when helping me choose the best pieces. It’s all top quality and they’re always right on time when they say they will be! I’m sure during the pandemic, things have been tough and they still followed the rules and found other ways like using online services. So creative and friendly. I wouldn’t use anyone else! Thanks to Nicole I think it was her name for helping me choose that Necklace! My wife loves it!!!” – Dale P.

Blown Away!

“I brought my wedding rings here today to be resized and I’m blown away by the professionalism, honesty, knowledge, and most importantly, the trustworthiness of this business. I think I arrived an hour before they opened, but they welcomed us right in and dropped everything and took the time to help us. I got my engagement ring back within a few hours and it looks absolutely stunning and fits perfectly. I can’t wait to see my wedding band.” – Jenna B.

The Rings of our Dreams!

“Both myself and my husband had SUCH a pleasant experience working with R&S for our engagement ring and both wedding rings. They were able to build us the rings of our dreams, and exactly what we had hoped for. They are extremely accommodating, deliver a premium service and product, and are just such a pleasure to work with. There’s no reason to look any further if you’re in the market for some new jewelry, especially for wedding/engagement rings!!” – Julie M.

Truly Care about their Customers

“I spoke with Robert on the phone and he was very eager to help. I met in the store with his father, Richard and he was the best jeweler I’ve ever encountered. He was knowledgeable with 40 years of experience, but what impressed my mother, sister and I, was how much he really cares about doing the right thing for his customers. He helped me find a gorgeous wedding band and was up front and realistic about everything with such dignity and sincerity. He’s mastered customer service and puts the customer first. Cannot say enough good things about him, his service and his products. The rings we looked at were so beautiful and he was so patient with us as we decided. Even buffed and cleaned my ring for free. Highly recommend.” Stephani V.
