Several black gemstones have gained such popularity
Black gemstones have a timeless beauty and enigmatic charm that capture the eye. From the glossy sheen of black tourmaline to the deep, velvety shade of black onyx, these stones have a certain attractiveness that makes them desirable for their aesthetic value as well as their metaphysical qualities. This piece delves into the realm of black gemstones, examining their traits, meanings, and well-liked kinds.
Several black gemstones have gained such popularity that they are now instantly associated with the color black. On the other hand, some gems are not as widely recognized among gem buyers, and there may be consumers who are unaware that certain gem species are available in black.
Is Black a Color?
The question of whether black is considered a color is a matter of technicalities. In gemology, color is typically described using terms like hue, tone, and saturation. Hues, such as red, blue, and green, are what people commonly refer to as colors. However, terms like black and white are associated with tone, which signifies the relative darkness or brightness of a hue. Black represents the darkest tone that a gemstone can possess. While the technical definition may vary, most gem enthusiasts and industry professionals commonly use the term “black” as a color when discussing gemstones.
Types of Black Gemstones
Black Diamond
Black diamonds stand out from their more traditional counterparts not only in their distinctive color but also in the unique way they acquire it. Unlike other diamonds that derive color from chemical impurities, black diamonds get their dark hue from numerous inclusions within the stones.
In the case of black diamonds, these inclusions are primarily composed of black graphite. Unlike chemical impurities that become part of the diamond’s atomic structure, inclusions are tiny specks within the stone. Graphite, a soft form of carbon, forms when the Earth’s pressure isn’t potent enough to create diamonds. Black diamonds contain numerous tiny graphite crystals, creating a clouding effect that gives the diamond its overall black appearance. It’s worth noting that while the graphite is black, strictly speaking, the diamond itself retains its characteristic hardness.
The natural process of inclusion-induced coloration occurs in black diamonds. However, some producers take it a step further by irradiating natural black diamonds. This process amplifies the graphite content in their crystals, intensifying the apparent black color of the diamond.
Despite boasting the famous hardness of 10 on the Mohs scale, thanks to their diamond nature, the abundance of inclusions weakens the crystal structure of black diamonds. While they remain highly resistant to scratches from natural materials, including other diamonds, the increased presence of inclusions makes these stones more susceptible to splitting with less force. Additionally, the surface of black diamonds may appear pitted due to these inclusions. Although undeniably beautiful, wearing black diamonds requires extra care, and using protective settings is advisable.
