diamond.
Colour, while useful to fair diamonds, is often misunderstood by people outer ascend the rhombus
trade.
Most people dream that all pallid diamonds are colourless. In reality, greatly colourless diamonds are
utterly unusual. The diamonds worn typically in ornaments are virtually colourless with pale golden or
bronzed tints. These diamonds globule into the typical colour magnitude. In the typical colour reach,
the faster to colourless, the more attractive and useful the shape.
In the 1950's, the D-Z colour grading climb introduced by GIA that stills the diligence yardstick.
GIA Colour Grade Scale
D - F: Colourless
G - J: Near Colourless
K - M: Faint Yellow

2. N - R: Very Light Yellow
S - Z: Light Yellow
How is colour calculated?
Colour in white diamonds is typically calculated by comparing the shape with the set of 'master sand'.
The maximum 'master rock' is E-colour. Any lozenge enhanced than the E-colour master is tempo d D-
colour.
Each colour grade is genuinely a thin vary of ensign. There is no one accurate colour for any GIA
colour grade scale. So, a F-colour shape can be a physically emotive, typical or weak F-colour. Though,
while the shape is better than the G-colour master, it receives a F-colour grade.
Fluorescence
Fluorescence is a total make that causes some diamonds to construct a glow (typically desolate or fair)
when viewing to a brilliant ultraviolet light. Some prefer a rhombus with some 'cobalt fluorescence'
because it may start the rhombus in the 'near colourless' or 'faint fair' ranges look somewhat whiter.
In the 'colourless' variety, fluorescence has no result on colour, although it can infer the rhombus to
have a little chalky appearance.
Why shape's colour grade is important?
The gleaming, fiery, sparkles of light that exude from an elevated attribute white shape are perfect by
some other gem. The rhombus acts related to a prism, isolating light into unearthly insignia, which are
then reflected as colour flashes, known as fire. Any regular colour in the lozenge filters the light,
lessening its fire and brilliance.
