When buying my engagement ring I had a very specific and unique design in mind. Not only were they able to create the ring I was looking for, they consulted me along the way with a level of detail and care that I've not received anywhere else. I was so pleased with Cooper jewelers that I came back to buy a Rolex from them. Once again their product quality, attention to detail and customer care was second to none. Thank you Cooper Jewelers!

Cooper Jewelers provided the exact service I needed. Elayne patiently introduced me to her extensive collection of luxury watches and I absolutely fell in love with my new Baume & Mercier. Jack ensured that the sizing was perfect and even added a new battery. I truly appreciated how easy they made the shopping process; just a few questions about my tastes and they immediately zeroed in on my dream timepiece. Exquisite tastes matched with easy personalities. I couldn't ask for more and I definitely know where I'll be going for my next big gift.

Popped in today to have a few watch batteries changed.the team was nice, thoughtful and worked quick to finish. While waiting around, I saw all of the cool watches and I will definitely be back to hopefully invest in one of the many beautiful IWCs. Great place in Warren, check them out

I went to Cooper Jewelers to get a ring for my graduation gift! It is truly my favorite ring. I wear it every day. It has 0.15ct diamonds and is a stack ring. When I Inquiryied about it, they gave me all the necessary information and even offered to resize it if it did not fit the way I wanted. I appreciate the thoughtfulness that Cooper Jewelers always showed me and I can't wait to come back for more diamonds! I mean, after all, they are a girls bestfriend!

DO NOT GO HERE Do not waste your time or money here. They are rude to their customers and have very poor quality control of their craftsmanship and diamonds. There are much better places who treat you with respect and value your time and money. My husband got my engagement ring made here and 4 times they messed up the resizing! Broke diamonds and then after I wanted my ring lowered because the setting was high they didn't want to! You made the ring we spent Thousands of dollars with you! Then then make me a new ring only to have diamonds fall out a week later! Never again.
