Aline is amazing to work with. I would highly recommend ADCO diamond. Aline worked with my fiance and I to obtain a Montana Sapphire which she so perfectly put in one of the gorgeous bands. She listened to everything that we wanted and also worked within our budget! So professional, attentive, and experienced. You will leave with a lot of knowledge and pure happiness!

I went to the jewelers building to see if I could find the perfect engagement ring. After visiting a couple shops on the lower levels, I didnt find much with my budget. We heard about ADCO Diamond from a family friend so we decided to try there next. They were very accommodating, easy to work with, went through every step of the process. We shared Espresso while going through some options based on the type of ring I was looking for. The ring is absolutely stunning! I also got the wedding bands done here as well. If I need anything down the road I will be stopping by again! The process was so easy and they love getting photos to share. Highly recommend!

The BEST! Aline & Rina are a pleasure to do business with. They are both gemologist and really know what theyre talking about. When my now husband and I went ring shopping, Aline spent a long time teaching us about diamonds. There was no hassling or pushy sales techniques. When we finally purchased my rings, it was truly a wonderful experience.Since then Ive had them make a custom necklace, using my mothers e-ring and diamonds from a bracelet I no longer wear. The result, a beautiful diamond flower with diamonds and emeralds added to necklace. I HIGHLY recommend ADCO!

Rina is fantastic. She got me the best price on a new engagement ring for my diamond and it was done and mailed back to me in just a couple of days. Very happy with their service and my ring looks beautiful!

I had 2 rings (14kt one garnets and one opals) custom made at ADCO.I knew of the Jewelry Exchange Building and street level stores from walking down Washington St. Once I needed several pieces of custom made jewelry I went to every store in the 8 floors of the building asking at all the jewelers.ADCO show the most interest and creativity at solving a problem of copying a ring from 50years ago.Their suggestion to create a CAD model (shown) of the ring to remove the bumps/scratches added a modest amount of cost, BUT the result were speculator.The new fire opals that were provided were of the finest quality that I have ever seen; even better than at the Gem Shows in Arizona.

As a guy who could be presented with 5 completely different diamond rings and not being able to tell the difference between them, I was very lucky to have found ADCO Diamond. I relied on Aline and Rina to help me make a custom engagement ring that my fiancée really loves. I chose ADCO Diamond instead of the other 6 different jewelers that I went to based on what I perceived as excellent customer service and reasonable prices. However, I would have chosen them over the others, even if they were more expensive due to my first meeting with them where they explained how things work and really took the time to listened to what I was looking for. This was not the same experience I had with many of the other places.I was not disappointed with my experience with ADCO Diamond. The ring and the customer service, exceed my expectations. They taught me about diamond value, the procedure for making custom engagement rings, and help me choose what would work well for a beautiful ring. I then added to the customization of the ring to make it special for my fiancée and Aline took me through what would work and what wouldnt. She even went above and beyond by adding little touches that made the ring very special; things I would not have thought of but made my fiancée very happy.I highly recommend to guys who are unsure about diamonds, rings, and this process, to find people who will help guide them through the experience while also getting a great price on the ring. So in brief, my experience was great customer service at a very good price for a custom made engagement ring. My fiancée and I will return again for wedding rings and other jewelry needs in the future.As the fiancée who received the beautiful ring from ADCO, I also cannot recommend them enough. I did not give my fiancé a lot to work with, just a list of some rough ideas and a friend to assist him. My tastes are fairly simply and classy but my favorite look was a rare one – a halo setting but with sapphires as the halo around a diamond. I knew that might be tough to find, so I gave other ideas as well. But he didn’t have to worry about that with ADCO – he was able to describe and show them my rough notes and they worked with my fiancé to create my dream ring that is so beautiful and simple and perfect (and yes – it has sapphires in a halo around a sparkling cushion cut diamond). We will definitely be returning to ADCO for other jewelry needs and I absolutely recommend them to others (including other future grooms who were only given a rough idea of what to buy).

Aline and the ADCO team were wonderful to work with. Aline sat with me for over 2+ hours and we reviewed about 5-8 different diamonds of various quality and we designed the perfect engagement ring. This was the key difference with the other jewelers I met. ADCO has quality and sizable diamonds in stock making the custom design easy to pick. We look forward to purchasing our wedding bands from you within the next few months! Thank you!-Doug and Anne

Best jewelry experience ever. Highly recommend for any of your jewelry needs. Aline and Rina are absolutely amazing.

Above and beyond expectations. Fast & Easy will definitely go to ADCO first for all my jewelry needs!Thanks Rina.

Amazing talent and perfectionist! Both of these ladies are so nice and down to earth. We started seeing them for just a sizing. Sence then she has made me earrings and an engagement ring and a band. She is so fairly priced and honest! You cant find a better jeweler in Boston, the quality the price and professionalism, trustworthy you just cant go wrong. Thank you so much for the years of service ladies!

Working with Aline was fantastic, even from out of state. She made the ring-buying process educational, exciting, and easy. And, she continues to be a huge help to my fiance. I would recommend working with her to anybody and look forward to purchasing wedding bands from her soon.

There arent enough stars to describe Aline and Rina. We have been customers for over 20 years and they have always treated us like family. If you need an education about diamonds theyll give you one. If you know exactly what you want theyll find it for you. Service after the sale is nothing short of astounding. This family is quite possibly the best jewelers in Boston, or even all of MA.

I have nothing but praise for Adco Jewelers on Washington St, in Boston. The entire experience was fun, no hassle, and informative. I purchased a fantastic engagement ring.I did a lot of research and Adco helped me pick out a great stone and band.The staff was super easy to work with and so friendly.

Beautiful selection of earrings and other jewelry, personal and warm service, reasonable prices. Rina and Aline are so easy to work with. Highly recommend Adco!

I worked with Aline and Rina and they were both absolutely fantastic. Every experience in there has a way of making you feel unique. I had a loose idea of what my fiance wanted in a ring and after about 4-5 visits with other shops it felt hopeless. If youve done this before you know what im talking about and if youre headed that way youll know soon enough- but there are a lot of poor diamond companies out there. Half the time in other shops I felt like I was being sold a used car. I never once felt that way with Aline. She is extremely knowledgeable and NOT PUSHY! With her help, we created an amazing ring that I catch my fiance staring at many times throughout the day.If you are new to the scene and recently in the market for an engagement ring, youd be a fool not to start here.

It is hard for me to believe that Gary and I will celebrate our 27th anniversary this June. Twenty eight years ago an uncertain young man walked in and out of jewelry stores and diamond dealers all over Boston, lucky to have found Norair Arshanian and Adco Diiamond Rina Arslanian Yokum (Adco Diamond).Norair, a diamond expert and also a proud father, took his time with Gary, teaching him about the 4 Cs to consider in diamond shopping for his future bride. No hard sales. No big pitch. Go out and look around and let me know if you need help. Of course, Gary looked around and recognized that not only was Norair giving him excellent advice, but that Noair was genuinely concerned that he would make the right choice and he was honest in all that he shared.Gary bought that diamond ring from Norair at Adco, proposing on one knee on a freezing cold January night on Bostons waterfront. Gary and I and that diamond ring (and wedding and anniversary bands we later purchased at Adco) have seen lots of life changes while raising 3 children and following our career paths in Maine.A number of years ago I decided I wanted to change the look of my engagement and anniversary rings and Norair was ready to help. He built the dream rings I had in my mind, using the 3 original diamonds. He was always there with a smile and a diamond wash each time we visited Boston and went back to visit. When I had a bad fall a few years ago and the paramedics had to cut all 3 of my wedding rings off my finger, Adco Jewelers stood ready to repair them and return them to my hand quickly and honestly.The last time we went into Adco, Norair was not there, but his smart lovely daughters seemed to know who we were and were gracious to us and proud to show us their stunning jewelry pieces. Honestly, I think we keep going back to visit Adco every few years just because they are like old friends as theyve been part of our lives every day since we said I do.If you, a friend or a loved one are in the market for a lovely high quality diamond jewelry piece, take the trip into Boston to Adco Diamond. Dont waste your time at jewelry chains or other dealers. Go straight to the shop where you are well served from the heart. They are diamond specialists, but more importantly, they are honest and kind. Thank you, Norair and thank you Adco. I hope to see you on our next Boston visit!

The ring is perfect! -my FiancéeThe Interactions that I had at (ADCO) were bold, but not aggressive or pushy. Aline is superb; she is a reputable dealer who is extremely friendly, kind, knowledgeable, accredited, and a graduate gemologist. I was on a tight budget and a really tight time constraint and she did everything she could to help me make my fiancée dream ring come true, within a short time frame. She ordered me an incredible custom made work of art, and the engagement ring was hands down the best price that I found between 8 stores from Massachusetts to CA including from a family friend gemologist who was willing to make the custom ring at her cost. When my (soon to be) mother-in-law brought the ring in to get it resized, Aline was very kind and helpful and charged nothing for the resizing and cleaning. I HIGHLY recommend ADCO for many reasons. They are a family owned and operated professional company that made a very difficult process as easy as I imagine it could be.Thank you Aline and ADCO.
