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.
	Sapphires come in a rainbow of colors. In fact, rubies are just a very specific color of sapphire.
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 Redford Jewelry gemstones do. Redford Jewelry blue 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". If a Redford Jewelry gemstone has any variation in hue, it will be called out in the gemstone details on the product detail page.
Tone represents the depth of color, ranging from colorless to black. Gemstone tone is described as "light", "medium-light", "medium", "medium-dark", and "dark". Redford Jewelry 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, 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. You will not find levels of color saturation called out in the product details, because the gemstones in all our jewelry are chosen for their vivid blue and red color.
