"Mark Stone is the ideal jeweler to see when it comes to buying an engagement ring. Knowing next to nothing about buying a diamond when I first met with him, he took his time explaining the various aspects of a diamond to me; he wanted me to have a thorough understanding of the quality of each diamond before I made the big decision. Throughout the whole process, he gave me the personalized attention that a first-time buyer like me needed. After deciding on a stone, we looked at numerous rings that he had personally designed as well as designs that I had brought with me. Once I knew what I wanted my setting to look like, all I had to do was leave him a picture, and he made it look exactly like (if not better than) what I wanted. When it was all said and done, I felt confident that I was walking away with the perfect ring for my fiance!" Brett Bukvic
"I needed an engagement ring with not just the right stone but I needed the setting to have a lot of detial. Not only did I get a great deal on the diamond he sold me, but the setting turned out more beautiful than I could have imagined... Thanks Mark!" Joel Wasserman
"Mark was always available and open to any question or concern that I had. In the end, I put my trust in him for one of the most important purchases I will ever make, an engagement ring, and he delivered on time and with great quality." Mark Coster

"Mark is one of the most honest and truly genuine people you will have the pleasure of doing business with. He treats people with respect and always has the needs of his clients first. I consider Mark a great friend and trusted advisor." Mike "Bernie" Klein
"I worked with Mark to create my now fiance's engagement ring and wedding band back in Jan/Feb '10. Throughout the entire process from picking out the diamond to the design of the band, setting of the diamond, and re-sizing the ring (my fault, not Mark's). Mark was knowledgeable, timely, and professional. I can't say enough about mine and my fiance's satisfaction with Mark's work... I plan to return to Mark for my wedding ring!" Steve Loeb
