They were informative and patient and really took the time to understand what I was looking for. They were flexible on my budget and it felt like they truly cared my best interest. It felt like much more than a transaction! I recommend them to anyone looking for an easy, thoughtful experience when making a decision like purchasing an engagement ring! What we chose was BEAUTIFUL and my fiancé loved it! We are so happy!
I came to Arvik and Zeki at Boston Diamond Studio with a set budget and only a rough idea of what I wanted -- and they absolutely exceeded my expectations. I left with a stunning, custom engagement ring AND wedding band that I'm completely in love with.
Even though I didn't know all the technical details upfront, they patiently guided me through everything. I ended up choosing a platinum solitaire basket setting with a hidden halo, and they helped me make the right choice for my style and budget. I recommend discussing if you want the ring to sit flush with your wedding band -- they made sure the final design aligned perfectly. Their attention to flush setting compatibility was especially helpful, as it's something many overlook but makes a huge difference in comfort and stacking.
The diamond they sourced for me was absolutely gorgeous -- a 4.1 carat, D color, VVS2 clarity -- and I genuinely couldn't be happier. They picked us the highest color (D) and one of the best cuts with minimal inclusions. They clearly know their diamonds and only offer the best specs within your price range. ( I was not as picky with my band as I was with my center stone engagement ring as long as the stack was flush).
There was a small mix-up with my wedding band (I received a different one than the one we originally chose during my consultation), but they corrected it immediately and free of charge. Their customer service is top-tier, and I truly felt they cared about my satisfaction every step of the way.
I also needed my ring resized, and they literally sized it in one day ( I used sizing beads because when I wear my band it will sit higher on the fat pad of my finger)-- so I didn't have to go without my engagement ring for too long. They clearly understand the sentimental value.
What amazed me most is that they did both my engagement ring and wedding band within the budget I came in with -- something other jewelers in the same building would've tremendously marked up. I'm incredibly grateful I chose Boston Diamond Studio over all the other options. I kid you not: name your price and they'll do everything they can to source exactly what you want. I do feel like I received such a good deal for the engagement ring and wedding band at a combined price. It is unheard of.
If you're starting this process, my biggest advice is: do your research, come prepared with photos, and know your desired specs. But even if you don't, you can trust Arvik and Zeki to create something beautiful for you.
Let me show you my pinterest inspo picture and what they made me -- and how accurate they were. The match is insane. Nothing bad to say, trust them! I will be a long term customer. Can't wait to create more bands with them in the future.
Thank you both so much!




Even though we moved away from Boston, we recently revisited the shop while we were in town to purchase our wedding bands. We would wholeheartedly recommend Boston Diamond Studio to our family and friends!
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.
