ASSIGNMENT 3 DIAMOND ESSENTIALS
WITH CORRECT SOLUTIONS
Annealing - ANSWER-A gemstone heating process that can be used alone or to
stabilize irradiated color
Characteristic color - ANSWER-The basic face-up color of a colored diamond
Colored diamonds - ANSWER-Yellow, brown, and gray diamonds with more color than
the Z masterstone, or that exhibit any other color face-up
Depth of color - ANSWER-The combination of tone and saturation that determines how
noticeable a color is
Fluorescence - ANSWER-Emission of visible light by a material when it's exposed to
ultraviolet radiation
Hue - ANSWER-Your first impression of a color; the basic color of an object
Irradiation - ANSWER-A treatment that changes the color of a gem by exposing it to
radioactive materials
Masterstones - ANSWER-A set of color comparison diamonds that defines GIA's
diamond color grades in the normal (D to Z) range
H - ANSWER-Which of the following GIA color grades indicates the greatest amount of
yellow
Brown and yellow - ANSWER-The most commonly encountered colors amony colored
diamonds are
Z - ANSWER-Which masterstone does the GIA Laboratory use to determine the point
where a yellow diamond transitions to the colored diamond grading scale?
Rarity - ANSWER-The price differences between colorless diamonds and near-colorless
diamonds are due primarily to
Tone and Saturation - ANSWER-To color grade a light yellow or brown diamond,
graders compare it to a masterstone for
Near-colorless - ANSWER-A general term for diamonds in the G-to-J color range
