What a client says

My fiancé searched for months for my engagement ring. He had an idea of what I liked so he went hunting at the Jeweler's Building Downtown. He went to EVERY store in the building to find the perfect ring and he found it at Platinum Studio by Z. The owner was honest and EXTREMELY helpful. He customized a BEAUTIFUL ring to our liking. I have to say I cannot stop staring at it. They even sized it the same day so that I wouldn't be without it for more than a few hours. I would like to thank the Platinum Studio by Z for making an elegant, timeless piece that I will wear for the rest of my life.
