Key facts about diamonds
in Tysons

Q: Are diamond certificates definitive?

A: While highly recommended and even indispensable as a guideline, diamond “certificates”
are essentially subjective evaluations. In fact, they are rarely called “certificates” by the labs
issuing them, because to certify means to guarantee. GIA (Gemological Institute of America)
officially calls theirs “Diamond Grading Report,” and AGS (American Gem Society) labels theirs,
“Diamond Quality Document.”

Q: Why the intractable confusion over diamond pricing?

A: A customer once asked after browsing for diamonds on the internet- and this happens all
the time- “Why was one 2 ct diamond, G color, VS1 clarity and ideal cut, priced at $24,500,

The answer is that no two diamonds, even graded the same color, cut, clarity and carat weight
are ever identical. Color and clarity grades are not absolute and at best represent a range, i.e.
there is no definitive F color.

Q: What is the “beauty” of a diamond?

A: When buying a diamond, most people rely on the “certificate” and on how great the
brilliancy of a diamond is as it appears to them when they are looking at it, most likely under
special “diamond enhancer” lighting installed by many jewelers above their diamond cases.

As important as brilliancy is, too much of it is actually detrimental to the overall beauty of a
diamond and hence its value. Too much brilliancy will in fact douse much of a diamond’s fire,
and drowns out the large flashes or pinpoints of color that a diamond needs to have complete
beauty. Achieving “fire” or, color dispersion, is where the art of diamond cutting is.
