Always amazing service at Derco! Last time we worked with Jim to get my partner a wedding band and he was kind enough to clean my jewelry and get my ring back to new. Today I went in and Jack helped me. He is always checking in and making sure the customers are alright. He cleaned my rings for me and they are good as new - ready to be worn for my wedding. Can't wait to come back again. Everyone working is efficient and helpful when it comes to jewelry. Can't wait to come back.

The service provided by Jack and his team is always excellent. I'm greeted upon entering, my jewelry is cleaned and checked without asking and they have a beautiful selection. Couldn't ask for better!

Christina was so patient with us in custom recreating the perfect ring we found somewhere else that wasn't able to fit the size stone we wanted. Definitely recommend and worth it even if each of the 8 times we came with customization requests was 2 hrs round trip for us.
