If you're looking for a trusted jeweler then you ABSOLUTELY need to pay Zeki and Arvik a visit. I promise you won't regret it! They're both incredible and work so well together to find and create exactly what you're looking for.

When my husband and I started talking marriage, we browsed around the Jewelers building and visited almost every store to find someone we could trust. Hands down the best decision that my husband made when he chose to work with them. The diamond that they found and the ring they created was absolutely breathtaking. So much so that I still find myself

I think I reviewed this place awhile back, but I need a new one because this place continues to be the BEST PLACE for diamond rings. The end.

The past 10 years I have been shopping for and buying diamond rings for myself and what I realized is that this is the only place that has modern designs that are not clunky, old fashioned like the '80s and 90s, and delicate.

I recently came back and bought a beautiful diamond necklace for myself. This place previously made me a beautiful custom Halo ring around a two carat diamond. The work is exquisite and I can't even control my excitement

Absolutely incredible. My engagement ring is all that I ever could have dreamed of, they did a fabulous job. They also were able to re-size my ring in 1 day! Dropped it off in the morning and had it back in the afternoon. Such a lovely place full of incredibly talented people. I could not recommend them more.

Got both of our wedding rings here - amazing quality! They are extremely helpful and made for a great experience. We also came back the week before our wedding and they cleaned all of our rings.

Zeki and Avrik made the process of buying a diamond for an engagement ring very easy and comfortable! They never pressured me on any one style or shape, just informed me throughout the process. I have since moved south of the city but I will definitely be going back to them for our bands in the future. I highly recommend this genuine shop for any engagement ring advice/purchases.

Arvik and Zeki were amazing! They worked with me for over 4 months to find the perfect diamond for my fiancé. They taught us both so much about diamonds, not knowing much going into the initial appointment with them. Through in-person meetings, email and text, they made sure to answer all my questions and requests. They also custom-made the ring setting. Even during the uncertainty and difficulty of 2020, they helped me find a ring that we both love. Would recommend to anyone!

I visited multiple jewelers during my search for an engagement ring. Among all the experiences, Zeki and Arvik are the best! They are so professional, and at the same time kind and patient enough to give me various suggestions while going with one setting over another with different diamond options. Although it was a very tight schedule between the day I purchased the ring and the day I planned to propose, they accommodated the schedule and created the engagement ring in such a short time! I couldn't be more satisfied with all the experiences I had at Boston Diamond Studio including the

This review is long overdue - I worked with Arvik and Zeki back in February to create a custom engagement ring from an heirloom diamond I'd been gifted. After sending an email for a quote, I received a response within a few hours and set up a date to come in to create a custom piece.

Arvik was so easy to work with and so kind. I was having an heirloom diamond reset from a previous setting into a brand new rose gold setting. I had some very specific ideas in mind and they were met with nothing but enthusiasm for the project at hand. I received CAD designs within a week (so fast!), and had

I had an amazing experience working with Zeki and Arvik to create the perfect engagement ring for my fiance. They are very honest and easy to work with, from our initial meeting through creating the ring. The ring came out even more beautiful than I could've ever imagined, and my now-fiance can't stop looking at the beautiful piece of art on her finger. I highly recommend anyone to stop by the Boston Diamond Studio!

Such a wonderful experience.

We had a thin engagement ring we wanted sized up. Twisted/spiral white gold band with small diamonds. They cut the band, added an 'extension' to the band, and were able to do the same twist in the metal - a great job. Very skilled!!

We are very very happy. Would go back in a heartbeat for future repairs, sizing, purchases.

Arvik and Zeki are very knowledgeable, extremely approachable, very skilled, and a pleasure to work with.

Thank you!

Zeki and Arvik are the ABSOLUTE BEST. The entire process is focused on treating the customer right and delivering exactly what you need and more.

The made the perfect engagement ring, helping me source the perfect stone then built a custom ring. Each conversation and visit was an absolute pleasure.

The engagement process can be stressful but Zeki and Arvik made everything so easy...including the price. Their quality and cost will beat almost all.

You won't go wrong with Boston Diamond Studio.

My [now, thanks in part to this amazing ring] fiance, as well as all her friends, family, and just about everyone she meets in a given day, is blown away by our 0.9 ct platinum engagement ring by Boston Diamond Studios.

Zeki was the first person I met over a very long day visiting nearly 15 different jewelers. He provided the best education of the day, along with the least amount of pushy salesmanship, and his patient advice had by far the greatest impact on my decision to purchase invariably the most beautiful ring and diamond I had come across.

Even more impressively, they were able to size

Boston Platinum Studio in the Boston jewelers building is my favorite go to jeweler for quality platinum maintainable/repair/ ring sizing in the Boston/cambridge/Somerville area. I can't recommend them enough! It is a small local family-owned business. The owners are the cutest couple and leave no detail overlooked. They go way beyond regular jewelry maintenance and saved my beloved wedding rings from every kind of abuse, from chicken spice rub getting under pave to full e-ring prong replacement and a full polish.

My son recently got engaged and we went together to look at rings. We went back and forth to several stores and he wound up buying the ring from Zeki and Arvik, a lovely couple who really did everything they could to make my son happy with his purchase. They were below anyone else price wise and they were able to obtain a diamond that my son was very happy with. If you are shopping for engagement rings or any high priced Jewlery, I wouldn't hesitate to go here first. Thank you Arvik and Zeki for making my sons experience so wonderful. If I have any need for jewels I will come visit you

I came to see Arvik and Ziki after seeing two other jewelers and was blown away by their professionalism and creativity. I had a family heirloom and needed a custom design, but struggled to find someone who could turn it into a modern engagement ring.

Needless to say, these two were up for the job. They were reasonably priced and kept me updated by text every day as the ring was designed.

So impressed by then and I HIGHLY recommend them to anyone looking for custom jewelry or an engagement ring

Zeki and Arvik are absolutely the best! I met them for the first time after my now fiancé brought me to their Boston location to get my engagement ring resized. I dropped off my engagement ring in the morning and I got it back within 2 hours! AMAZING!! I love my ring so much! Thank you Zeki and Arvik for your patience and outstanding service!

We would definitely recommend Zeki and Arvik to anybody looking for any type of high quality jewelry and we will be coming back for our wedding bands.

I realized once I searched for jewelers, it was fate that brought me to Zeki & Arvik. They were founded in 1990 (the year I was born) and are located in suite 226 (the month & date of my birthday.
As a husband & wife duo, they balance each other. They are patient, knowledgeable, and honest.

We had a family diamond that we wanted to use and incorporate into the ring. We searched and searched for the right setting, but nothing seemed to look right. Then Arvik went over to a different display case. I then looked down said, "how about that one?" as I pointed to a beautiful

Avrik and Zeki are the best! We came here looking for a wedding band to match my unique engagement ring. They worked with us until it was perfect (which included making a second wedding band when the first wasn't what I thought it would be). Can't recommend them enough!

You HAVE to go here if you are looking for the perfect piece of jewelry for any occasion. Arvik and his wife provided the BEST customer service and helped me throughout the whole process of finding the most amazing engagement ring. They both worked with me to understand quality of diamonds, and what best fit my ideal ring, and budget.
