The CIBJO or the International Confederation of Jewellery, Silverware, Diamonds and Stones developed the International Clarity Scale for grading diamonds. This clarity scale mirrors the GIA grading scale, except nomenclature varies. The CIBJO system names these clarity grades; Loupe Clean, Very, very small inclusions (VVS1 and VVS2), Very small inclusions (VS1 and VS2), Small inclusions (SI1 and SI2), Pique (P1, P2, and P3).

Clarity grading by CIBJO standards is by examination using a 10x achromatic, aplanatic loupe in normal light.

Famous quotes containing the word des:

    When I was growing up I used to think that the best thing about coming from Des Moines was that it meant you didn’t come from anywhere else in Iowa. By Iowa standards, Des Moines is a mecca of cosmopolitanism, a dynamic hub of wealth and education, where people wear three-piece suits and dark socks, often simultaneously.
    Bill Bryson (b. 1951)
