The beautiful color
of a gemstone is its most defining characteristic, and many jewelers consider
it to be the most important evaluation criterion. When deciding upon gemstone
color, examine hue, tone, and saturation.
HUE
The most valuable gemstones are those that exhibit a pure color and only
"slight" hues of other colors in addition to their primary color, as all
BlueStarJewelry gemstones do. For example, BlueStarJewelry sapphires range in hue
from "slightly purplish-blue" to "slightly greenish-blue," pink sapphires
always range from "pink" to "slightly purplish-pink," and rubies range from
"slightly orangish-red" to "slightly purplish-red". With the exception of
opals, variation in a gemstone's hue will be called out in the gemstone details
on the product detail page.
TONE
Tone represents the depth of color, ranging from colorless to black. Gemstone
tone is described as "light," "medium-light," "medium," "medium-dark," and
"dark." BlueStarJewelry offers gemstones with the most sought-after tones that
fall within the medium-light to medium-dark range. For all of our gemstone
jewelry, you'll find any tone variations are called out in the gemstone
details.
SATURATION
Saturation, or color purity, refers to the degree to which the gem is free from
brown or gray hues. The most desirable gemstones, which show little gray or
brown, are often described as having "vivid" or "strong" color saturation.
Generally, the levels of color saturation will not be called out in the product
details because the gemstones in our jewelry are hand-selected for their vivid
colors.
