gia certificate We don’t sell our diamonds online, and here’s why.Design by Sevan While it would be profitable for Design by Sevan to sell online,
it’s not in the best interest of our loyal customers. Every diamond in the world is unique and complex, and a diamond’s ratings alone can’t possibly express its beauty and brilliance.

Two diamonds with identical ratings can look drastically different. One might be amazingly gleaming while another with the same rating could be as lifeless and dull. We never recommend anyone buying a diamond without seeing it in person first.

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

Design by Sevan devotes itself to being different. Our diamond buyers, Herman And Sevan, go overseas three to four times a year to Belgium and northwest territories. It’s expensive and time-consuming, but it allows us to offer our customers a selection of the most breathtaking diamonds possible. Each diamond we sell is hand-selected by us after a careful evaluation. We only sell diamonds we are proud to put our name on.

We uphold our high standards of exceptional quality diamonds, integrity, and trust. Each loose diamond is accompanied by a grading report from either GIA,HRD,IGI or AGSL, independent diamond grading labs with the most stringent grading scales.

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
