Wonderful to work with Matt and Lisa at CDI to “re-imagine” a diamond ring. They never disappoint. Friendly, top notch service and quality jewelry.

Matt & team were very helpful to me as I purchased an engagement ring. Matt was willing to walk me through my options via texts and calls weeks in advance of my appointment in the store. The ring turned out beautiful! All-around great experience and I will be going back.
