![]() ![]() Star sapphire, for example, derives both its value and its name from its needle-like inclusions. Some precious stones actually increase in value due to their inclusions. But it’s not always that simple.Ĭosmetic inclusions do not always mean lower quality. That’s why, in most cases, gems are valued higher when they are glassy and utterly transparent. These interruptions in clarity can affect the visual appeal of a gemstone, as well as its durability. Inclusions and blemishes can often add character to a gem, giving it a unique fingerprint. Precious rocks that contain cloudiness or other visible markings within are said to have inclusions, while stones with markings on their surfaces are described as blemished. For example, if a gem displays excellent clarity and color, the value does not simply increase linearly with the carat, but instead rises exponentially.Ĭlarity refers to a gem’s degree of transparency. While gems of a higher carat are often more highly valued, the other three Cs each have a significant role to play. The size of a gemstone is generally measured by weight in metric carats (one carat is equal to 1/5th of a gram). Let’s take a closer look at how the Four C’s are applied to colored gemstones. For example, color, just one of the four factors, has four elements of its own: hue, saturation, tone, and coverage. While the Four C's are well established when it comes to grading precious stones such as diamonds, their application to fine colored gems is a little more complex. Whether you plan to buy one gem or begin a collection, it is worth your while to understand how each of these factors affect your investment. ![]() The Four C’s of Colored GemstonesĪffectionately known as the Four C's to us gem nerds, Carat, Clarity, Color, and Cut are the four yardsticks used to measure gemstone value. To determine the monetary worth of an emerald, ruby, or sapphire, multiple factors are considered. And when you think of gems as snapshots of ancient geological history, each and every one is precious.īut alas, appraisers must assign a value, or price per carat, to each gemstone. Even a humble stone can hold priceless value when it carries memories and meaning. The true worth of a gemstone can only be measured by its owner. ![]()
