Zeki picked up the call and was genuinely warm and friendly to talk to and told us to come right over. When we got there she kindly welcomed us and had us sit down and from scratch her and Arvik patiently helped us compare shapes, sizes, stones, settings, bands, the whole nine yards until we built the perfect ring that my fiancé and I both knew there and then was the one. The whole process with them felt like what we hoped for but couldn’t find.
The next part was the hardest and that was keeping it cool and hiding a bit of my excitement from my fiancé and subtly signaling to Zeki and Arvik that I would call them as we made our way out. The next day I called and placed a deposit and within a week or so the ring was complete and I snuck to pick it up.
Fast forward and my fiancé and I just got our wedding bands from them too which was just as memorable and pleasant!
We both couldn’t be more thrilled with the timeless rings we’ll be wearing for the rest of our lives and the wonderful experience you two provided 🙂
Thank you again Zeki and Arvik for your knowledge, professionalism and care
knowledgeable and kind. They spent a lot of time with us going over many different ring options and letting me try them on. I love my ring. It is exactly what I wanted.
Zeki & Arvik made the engagement ring purchase process as easy as possible. They honored their promises (had the ring ready ahead of schedule), were very friendly, and made sure I was setup for an elated fiancée. Also added an insert for a snugger fitting after proposal day. Highly recommend!

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.
