Zeki & Arvik are absolute Perfection! I’m picky and looked for a jeweler for over 3 years to create the perfect low-profile/practical setting for an engagement ring - we worked together side by side and they guided me with patience to the ideal custom setting. They’re so skilled and knowledgeable at their craft. I highly recommend Platinum Studio by Z for any of your jewelry needs. I am a customer for life!

I had an OUTSTANDING experience working with Zeki and Arvik at Boston Diamond Studio.

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!

Absolutely blown away by the service and quality!! My husband and I cannot recommend Boston Diamond Studio enough! They are super flexible, timely, caring, meticulous, talented - and best of all, genuinely so nice. We used them for my engagement ring and for a diamond tennis bracelet. Cannot recommend them enough.

Beyond Grateful - GORGEOUS Custom Ring Within Budget!

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!

Words cant express how thankful I am for Arvik and Zeki! From the start, they were both so extremely helpful and kind to my fiancé and I! We have purchased my engagement ring, both of our wedding bands, and even a gold bracelet! I get so many compliments on my ring all the time!! I can’t recommend them enough!!

If you are looking for an engagement ring you have come to the right place! Arvik and Zeki were an absolute pleasure to work with and they were so helpful. They made me feel so welcomed. I went in and told them ideas of the ring I would like and they made it happen in minutes! They helped me craft an amazing and gorgeous ring. They never rushed me or made me feel like a bother as I came back 3 days in a row to double check that I loved what I picked and was sure about it and each time they welcomed me in with open arms. They had the ring done so quickly and when I went back in after to get it sized they got it back to me the same day, 3 hours later! That is unheard of! It was just further proof that me fiance and I made the right decision. Their knowledge and love for their craft is very evident and I am so happy I found Boston diamond studio as I will now be a customer for life.

We were absolutely blown away by the service and quality we received. I had an image in my head of what I wanted, and they were able to make it a reality and exceed my expectations! Beautiful ring, amazing quality, and the nicest people to work with. We’ve gone back for our wedding bands and love those too. We had to go back to fix my engagement ring after I dented it, and they were fast, helpful, and so kind. I recommend them to everyone I know!

This place continues to be our favorite spot! They helped my husband get a really fair price for my engagement ring and they made the whole process stress-free and informative. I get so many compliments on my ring and I love telling people where I got it. We go back to them now for different things and each time they are so attentive and helpful. They are the only place I recommend people when starting their ringing searching journey

My fiancée and I visited Boston Diamond Studio to look at settings and diamonds when we were exploring engagement ring options. During our visit, we appreciated Arvik and Zeki’s genuineness, transparency, knowledge, and trustworthy nature. In particular, we appreciated Arvik’s style recommendations which helped us choose the perfect ring! They gave us fair pricing for the ring and we are extremely pleased with the end results.

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!

My now wife and I purchased an engagement ring last spring and couldn't be happier with the ring itself and the service. Zeki and Arvik were kind, knowledgeable, and made the process very straightforward.

Awesome experience getting a bespoke made piece within a fast turnaround time and a competitive market rate. I appreciate how responsive Arvik and Zeki were to requests, offering their insights and professionalism to make the desired piece possible. Highly recommend working with them to make things happen, where quality is not compromised despite turnaround times.

My (now) fiancé and I both can’t say enough good things about Boston Diamond Studio. My fiancé and I started looking at engagement rings together so when “the time comes” I’d have a pretty good understanding on a direction to go. Our search initially started elsewhere and we weren’t gaining progress, we left the jewelers feeling more confused and uncertain than before and some had us feel like a burden. Just when all hope was lost and with our potential marriage in shambles (kidding) we called Boston Diamond Studio.

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

My fiancé and I had an amazing experience here. The owners were very
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.

Long time coming - my fiancé and I got engaged on New Years Eve of last year, and Boston Diamond Studio created our dream engagement ring!!! We did a lot of shopping around for the perfect setting for a family heirloom diamond, and the second we met Zeki and Arvik and saw their work, we trusted and knew this was the spot. The experience was very personalized and special. I love the ring more each day. We'd recommend Boston Diamond Studio to anyone!

UPDATE: It was an easy choice to return to Boston Diamond Studio for our wedding bands. Zeki and Arvik guided us through the process with professionalism and care once again. Their selection and quality of jewelry are excellent, but it's the customer service and communication that truly set them apart. Making a purchase as significant as rings can be daunting, but I felt fairly treated and well served throughout the experience. Highly recommend Boston Diamond Studio!!!

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!

Boston Diamond Studio helped create the ring of my fiancée's dreams and the exact design I had envisioned. First of all, I was looking for a lab made yellow diamond with particular specifications for the center stone. While other studios I checked out required lengthy and expensive processes just to be able to see such a diamond in person, Boston Diamond Studio showed me a perfect yellow diamond in person during my first visit to their store at no cost to me. During that first meeting, they were also fairly willing to work with my budget. After that, they were very knowledgeable while helping me craft the perfect ring setting with design suggestions that were respectful of the vision I had initially laid out. Once the final design was submitted, they were fairly speedy in their delivery of the final product. Most of all, I appreciate the cheerfulness and professionalism that characterized all of my interactions with the pair at Boston Diamond Studio. I'm happy I found them, and I'm so grateful to them for helping me craft the perfect ring.

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.
