This is THE place to get the ring. Greg is an absolute fantastic person to work with and his designs are flawless. He is patient, flexible, can work with any budget, and is incredibly welcoming. He makes the process stress free and super clear. My now fiance loves her custom ring and we’ll most likely come back for the wedding bands! Highly recommend!

From our people
I purchased an engagement ring online from their website. It was very easy. They contacted me right away and the communication was excellent. The ring shipped in a timely manner as they said 3 weeks and it came in 3 weeks. The ring came and it was AMAZING!! my fiancé was ecstatic. I highly recommend Jacob Mercari. Wish I could give more than 5 stars.
