Diamond GIA grading reportIt’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 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!

  • 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.

  • Sevan is the man! I had a very stressful experience looking for a diamond engagement ring before finding Sevan at AST Jewellery. He is a very likable and easy to speak to and gave me great advice through the whole process of designing a custom ring. He seemed more interested in creating a tasteful ring rather then selling me the largest diamond I could afford which was really appreciated. Also the rings he has on display are very well designed and crafted which left me confident I was in good hands. I had some ideas about creating a custom ring and he was able to take them and create a ring that went above and beyond my expectations. I am very pleased with the service and the ring I got at AST Jewellery and will definitely be returning to get wedding bands done or any other custom jewellery in the future.
