Mervis is the absolute best there is! They helped us every step of the way and my soon to be wife is absolutely thrilled with the one of a kind beauty of both her engagement ring and wedding band. Elizabeth and Ronnie made our ring purchases a truly special experience and I will without question be a customer for life.

Janette was amazing from start to finish! We went in with no experience purchasing diamonds, she gave us a crash course and guided us the whole way giving us options and suggestions to assist us with our purchase. She was so friendly and knowledgeable as well as the other staff who stepped in on days Janette was not working. We are so happy with our purchase and very pleased with the service provided at Mervis Rockville!

My fiance and I got an engagement ring from this location a while back and Ive been meaning to write this review. Janette took care of us and she is really the best! She was extremely attentive and overall just super helpful. She provided us with plenty of options and lead us guided us with professional opinions. I strongly recommend visit Janette at the Rockville location.

Monica was absolutely fabulous. I came in to replace the band on my engagement ring. She was super transparent and went above and beyond to make sure I knew what I was purchasing. I'm very grateful for the time she took to explain and confirm with multiple designers to make sure I got exactly what I wanted and needed! Thank you!

Monica park was exceptionally helpful and wonderfully accommodating! She not only took care of me but went above and beyond to help meet our expectations. She is very well spoken, took the time to explain the process and she was sweeter than honey. I highly recommend to any new clients who may end up at Mervis, to seriously consider Monica as their diamond advisor for she will get the job done and have you leaving with a big smile:

Robert B. was a great help! I came in looking for an engagement ring not knowing anything about diamonds. Not only did I leave with a BEAUTIFUL ring, but also a free education on diamonds. He was even kind enough to show me colored diamonds, which I had no idea they existed! Mervis has special people! I highly recommend it! Thank you Robert for making this purchase so easy and simple!
