When I needed to have my diamond reset in my ring, I went shopping for a reputable jewelry store. Honestly, I had a hard time finding one where I felt comfortable leaving my diamond, until I met with the extremely professional staff at Carl Greve Jewelers. I was so impressed with how they were so helpful and professional. They took me into a back room where I was able to look at my diamond through a microscope and they didn't make me feel bad for being extra cautious (other stores had gotten upset at the request). Additionally, the store is very elegant, and they have a beautiful selection of jewelry. Most importantly they seem to be very trustworthy and honest. I would highly recommend this store for jewelry shopping or repair.
Pros: Trustworthy/Honest, Quality, Worth the expense
