Jasper, a type of cryptocrystalline quartz, is known for its diverse range of colors, which can vary greatly depending on the presence of impurities and the conditions under which it forms. The color of jasper can range from a deep, rich red to a soft, creamy white, and can also include a wide spectrum of other colors such as yellow, green, blue, and even black.
Primary Colors of Jasper
Some of the most common colors associated with jasper include:
- Red Jasper: This type of jasper owes its deep red color to the presence of iron oxide or hematite. Red jasper is often used in jewelry and decorative objects.
- Yellow Jasper: Yellow jasper can range in color from a bright, vibrant yellow to a softer, more golden hue. This color is often the result of the presence of limonite or sulfur.
- Green Jasper: Green jasper can vary from a light, pale green to a deep, rich forest green. This color is typically due to the presence of chlorite or other green minerals.
- Blue Jasper: Blue jasper is less common than some other colors, but can range from a pale sky blue to a deeper, more azure hue. This color is often the result of the presence of azurite or other blue minerals.
- Black Jasper: Black jasper, also known as “blackstone,” is a type of jasper that is characterized by its dark, rich color. This color is often the result of the presence of manganese or other dark minerals.
