gia certificateIt’d be easy (and very lucrative) for Design by Sevan to sell diamonds online, so why don’t we? It’s just not in the best interest of our customers, and here’s why.

Every diamond in the world is unique and different, and a diamond’s ratings alone can’t possibly describe its beauty and brilliance. Professional diamond buyers know that two diamonds with identical ratings can look drastically different. One might be amazingly brilliant while another with the exact same rating could be as lifeless as an ice cube. That’s why a diamond is one of the worst possible items to buy sight unseen.

The fact is, many online diamond companies don’t own their own diamonds—they’re simply looking at a grading report and often don’t actually see the diamonds they’ve sold before they’re shipped to the online buyer. How can you know what you’re buying if they don’t know what they’re selling?

Design by Sevan is different. Our diamond buyers,Herman And Sevan , go overseas three to four times a year to belgium and north west territories. It’s expensive and time-consuming, but it allows us to offer our customers a selection of the most breathtaking diamonds possible – diamonds we’ve seen and exhaustively evaluated in person. Diamonds we are proud to stand behind.

What is Diamond Fluorescence?

Diamond FluorescenceFluorescence in some degree is common in a great percentage of diamonds. Fluorescence is a form of illumination that is created when a diamond is exposed to low or high wave ultraviolet radiation. Faint or medium fluorescence will rarely affect a diamond’s appearance. Usually fluorescence is unnoticed by the human eye in ordinary light. Fluorescence can cause a diamond to appear less clear or slightly hazy if the diamond exhibits very strong or extreme fluorescence. When selecting your diamond it is best to choose a diamond that has no fluorescence or faint to moderate fluorescence.

Diamonds that possess strong fluorescence in color grades lower than the color grade of H will often face up approximately one color grade better than a non-fluorescent diamond. Strong fluorescence can actually improve the appearance of diamonds that possess traces of color. Diamonds that possess strong fluorescence in colorless to very near colorless grades D through G sometime exhibit a noticeable luminescence which can give the diamond a hazy appearance. A strong or extremely fluorescent diamond can usually be purchased for 10 to 30% less than a diamond that possesses fluorescence that is moderate or better.

Listed below is a list of abbreviations for describing strength of fluorescence:
  • N, NO, NON, – No Fluorescence
  • F, FB, FT, FA, – Faint or Faint Blue Fluorescence
  • SL, SLB, SLT, – Slight Fluorescence
  • M, MO, ME, MD – Medium or Moderate Fluorescence
  • S, ST, STB, STG, – Strong Fluorescence/li>
  • E, EX, EXB, EF, – Extreme Fluorescence

  • 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

  • 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..

  • 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!
