I live out of state & dealt with Jonathan by phone & email. He was very professional, quick to respond to emails and always available to speak to whenever I called for him. Everything was handled in a timely manner. This is especially important when dealing with pieces of jewelry that have sentimental value. I would recommend Delmonte-Smelson and if needed, do business again with them in the future! Thank you!

I was introduced to John by a mutual friend and let me say I'm sure glad I was! He went above and beyond for me when creating my fiance's engagement ring. From picking the stone, to designing the setting, production and delivery John was there every step of the way. Even had to get it sized bc I didn't know her actual finger size and he was so accommodating. He made this process seamless, and pleasurable! I am a client for life. Thank you again!

Phil and his team are amazing. I purchased a ring back in January and it was quick, easy and beautiful. I showed them a picture of what I was envisioning and they turned it into a reality. They're so talented, especially Phil. My fiancee tells me regularly how much she loves her ring. Fellas, this is the place to go for a beautiful, unique, custom piece.
