I searched the internet for a reputable jeweler. I came to Diamond Castle for the first time to have a ring appraised and re-sized. The owner of Diamond Castle knows he has two things to market...his products and his honesty. When he first inspected the ring, he said that he first had to take in into the back to have it cleaned. I thought, "Here we go..." He held the ring up at eye level and said, "Follow me." We followed him into the shop that has two very large picture windows. We watched as he cleaned the ring and walked back out to the counter. NOT ONCE did we lose sight of the ring. Then we asked about having it re-sized. He gave us a fair price, and I asked if we needed an appointment. He asked, "Do you have time now?" (I thought re-sizing was an overnight thing.) We came at the right time. He told us it would only take about 20 minutes. We agreed. Back the ring went to the windowed shop, with us following. We stood in front of the huge window and watched the expert jeweler (2 feet away and facing us) perform the re-sizing as well as tightening the stones and cleaning it. Again, NOT ONCE did the ring leave our sight. As I mentioned, the owner of Diamond Castle knows he has two things to market...his products and his honesty. He does both very well.

Susan: Cathy F

My husband and I have been going to Diamond Castle since they opened in Marlboro. Cathy has always gone above and beyond to help me find the perfect gift, and if they didn't have it, she would get it for me or have it created. Cathy guides my husband with every piece he buys, and I am always amazed by my beautiful "one of a kind" gift. Wouldn't go anywhere else!
