Sevan was absolutely wonderful to work with. He was so helpful in bringing our vision to life for our engagement and wedding rings, and he made our budgets work! He was really responsive, took time to show us lots of options, and even told us when we were going a little overboard for no real reason. The entire experience was amazing and we’re thrilled to have Sevan as our new family jeweller 🙂

I came across Sevan’s website and knew right away that he would be the one designing my new engagement ring. The artistry and craftsmanship are unique in kind and quality. Sevan is also happen to be a very warm, genuine, patient and honest individual. I never felt rushed or pressured in any way. The entire experience was stress free. He was responding to my inquiries right away and was providing regular updates on the progress so i never had to wonder or worry. Very happy with my new “jaw dropper”. It’s stunning! Thank you, Sevan


If you are looking for a piece of custom jewelry, stop googling other jewellers and set up an appointment with Sevan. I spent many hours researching and visiting other jewellers before meeting with Sevan. In every aspect, Sevan is superior.

I was referred to Sevan after deciding to purchase an engagement ring. He made me feel at home in his office and educated me on diamonds in a unique way beyond the typical 4 Cs of diamonds you hear from other jewellers. When I met with other jewellers, it felt as if they were trying to upsell me; Sevan was always trying to do what he could to get me the most for my money and keep me within budget. After telling him the cut of stone I was interested in getting he quickly brought in options for me to consider. Sevan has an amazing eye for stones and found the right stone for me in a very short time period. He then designed a beautiful setting for the ring. After finalizing the setting, I wanted to propose the next week. I did not think it would be possible to have the ring completed that quickly but Sevan surprised me and completed the ring in time. The final product is beautiful. Most importantly, she loves it.

I wasn’t sure what to expect when going in for a consultation, as I had no knowledge about diamonds or jewellery at all. All I had was an idea of the design that I was looking for and a budget. Sevan sets up personal appointments, so there is no interruptions from other customers as you would have at other jewelry stores. Sevan is very personable, very knowledgeable and professional. He gave me different suggestions and recommendations that would meet both of my requirements, making it so much easier on selecting the band and the diamond itself. I got carried away with some suggestions and he advised me that it would have made the ring more cluttered and cost more, which showed me he knows what he’s doing and always keeps your interest in mind. He is also very accommodating to meeting your timelines.

The ring I received was beautiful and far beyond what I expected it to be. I was really impressed with his work and the outcome of it all was a big YES! She loves the ring! We are both very happy and we will definitely be going back to Sevan for our wedding bands. I would recommend Sevan to anyone who is looking for the perfect ring or design. Keep up the good work Sevan

Design by Sevan provided me with a positive diamond buying experience. Sevan always took the time to make sure I was well educated in the diamond I was buying. I went into the whole experience with very little knowledge about diamonds but Sevan made me feel very comfortable and confident that I was getting the right diamond. I would not hesitate recommending family and friends to Sevan because I know they will be getting great service, a great price, a great diamond, and a wonderful experience. Thank you again! Much appreciated.

Sevan is…for lack of a better term…the man! My fiance has had her engagement ring for over a year and loves it just as much today as the day I proposed and she still gets compliments on it from random strangers. As a guy, buying an engagement ring can be a pretty intimidating and a slightly terrifying experience. Sevan is calm, honest and to the point. I shopped around quite a bit and found Sevan to be the best on price and on style. I tried big stores like Birks who offers you Perrier when you come in the front door (guess what – you pay for that whether you think so or not) and smaller independent places on Queen west (which was definitely more expensive and I wouldn’t even have been given the opportunity to choose the diamond myself!). Beyond the far better prices and quality design, the best part of my experience with Sevan is that he actually seems to have your interests in mind. We stayed within my budget and he helped me pick a great diamond. Normally most jewelers just go by the four Cs…but Sevan taught me about things like the size of the diamonds table. Which meant that he ended up suggesting a diamond which had a smaller carat size but looked larger to the naked eye because of the table size. He also emphasized the proportions of the ring which can influence how much it sparkles…or the ‘fire’ rating of the diamond. All this to say we are incredibly happy with Sevan and his work and will be going back for our wedding bands..

I found Sevan through a referral and he most certainly has lived up to the reputation that precedes him. Sevan helped in all aspects of conceptualising; sourcing and building the most amazing custom engagement ring. His office is conveniently located in downtown Toronto. I travelled from Ottawa to meet Sevan and found it very easy to get from Toronto Island Airport to his office in minutes. Sevan and his office are both welcoming and put you at ease as you venture down the path of making a very large purchase. He instils confidence and trust when you meet him; which will allow you to move beyond validating your jeweller and on to the fun part; designing a dream engagement ring. He spends time ensuring he understands the concepts and then lays out your options out front to ensure price and expectations are in line. We spent a few weeks looking for the perfect cushion cut diamond that blew me away. After the diamond was sourced and purchased we quickly moved to make the ring. Sevan met and made every timeline I asked of him. The communication during the process was excellent and I rarely waited minutes for a response from him. I highly recommend Sevan for his professionalism, customer service and ability to deliver on the most amazing custom engagement ring and would be willing to act as a personal reference for his work and character

Dear Sevan, We’d like to take a moment to send our sincere thanks for the truly personalized experience you created for us. I was so impressed with the design you and Martin came up with for my engagement ring! It was an incredible surprise and the custom elements of the ring matched my personality perfectly. Working with you to pick out our wedding bands was equally exciting and we love that we finally get to wear them every day! When it comes to customer service, you went above and beyond… We really felt like we got the “friends & family” treatment (rare, given that Martin stumbled across your site via a Google search). To anyone thinking about doing business with Sevan: we experienced honestly mixed with a genuine attention to detail and commitment to making the perfect piece(es) of jewelry to last a lifetime. We couldn’t be happier. Sending so much gratitude, Stephanie & Martin

Sevan was absolutely amazing to deal with. He found the perfect diamond and complemented it with an incredible design. I live in Ottawa and his store is in Toronto, and I never even needed to make the trip. We exchanged emails, designs, and phone calls in order to complete my request and my ring is even more beautiful than I could have imagined. I would absolutely recommend him to anybody and everybody I know. Thank you Sevan for my perfect dream ring..

After having numerous poor experiences in retail stores and not finding what we wanted, we ended up in Sevan’s office. He was professional and could almost read minds as to what we were looking for. The finished product was perfect, great quality, fast service and had much more value than retail purchases. I would highly recommend Sevan for any jewellery purchase. He is the besT!


We had an amazing experience with Sevan! We had to have our wedding rings designed on short notice and Sevan delivered on time and the rings turned out absolutely beautiful. The experience at his studio is pleasant and he is very patient. He provides a lot of valuable information with regards to style, and type of metals that would be optimal for certain designs. Sevan’s experience shows. He is a true professional and knows his art form in out. We would recommend Design by Sevan to anyone looking to get a truly personalized engagement ring. Thank you Sevan.

Buying a ring from AST was a fantastic experience!! Can’t say enough nice things about Sevan. He runs an honest, pressure free business and has become my go to guy for all my jewelry needs.

If you’re looking for a diamond ring for that special someone Sevan will make you the ring of your dreams for a fraction of the cost of the big guys… and treat you with respect along the way.

Could not be happier!! Highly recommended!!

My girlfriend and I (now fiancée) were referred to Sevan at AST Jewellery by a friend of ours.

Taking a look at his site we found something we wanted (she wanted a coloured stone and we landed on sapphire) to which we promptly set up a time to go meet him and try it on!

Not only was he quick to respond but he made us feel very comfortable with our flurry of questions and took the time to explain various cuts, clarity, etc. This man knows his craft very well and we could tell how passionate he is about it.

We figured out what we wanted and moved forward. Sevan takes you along every step of the way, is honest, assuring, kind and simply a genuinely nice person. When making a big purchase and a big decision like getting engaged it just amplifies the excitement when the person you’re buying the ring from is so fantastic.

A brilliant experience. Highly recommended and we’ll be back for the wedding bands and be referring any of our friends to him.

Thanks Sevan!

I was referred to Sevan and AST Jewellery by a friend. Prior to meeting Sevan, I met many jewellers and saw many diamonds and rings. Sevan was very passionate, straight forward, and honest about everything. More importantly he was more than willing to work with me and my vision. He was not only able to teach me more about diamonds but he was able to help me find one that was perfect. I have since proposed and my fiancé is in love with the ring. I will be going back to Sevan for the wedding bands and recommending him and AST Jewellery to all my friends and family.
