How To Identify Coquina Jasper
Coquina Jasper isn’t usually enhanced or treated in any way, like many stones on the market. These beautiful stones will take a medium to good polish. However, the hardness level can vary, and the stone sometimes contains tiny surface pits.
According to the Mohs Hardness Scale, Coquina Jasper ranges from 6.5 to 7. However, the hardness can easily vary from one stone to the next. While the stone is typically classified as a variety of Jasper because of its grainy structure, scientists often classify these beauties in their own category.
Coquina Jasper’s color is mostly a brownish to reddish hue with stripes or streaks of orange-yellow patterns. Some specimens appear to have hints of gold color.
Don’t be fooled. It might seem like this Jasper variety is complicated to imitate because the patterns look like incredible works of art. But there are amazing artists with the skill and talent to duplicate faux versions.
Real Jasper can be difficult to identify and distinguish from other natural minerals, especially Chalcedony varieties. However, Jasper varieties can be easily distinguished from fakes made of plastic and glass.
To identify most Jasper varieties, all you have to do is check the stone’s hardness and diaphaneity. Use a bright flashlight to light the Jasper specimen in question. If the material doesn’t transmit light through the thin slices, you have a real Jasper. Faux or fake Jasper made from plastic is softer and can be scratched with a knife. They will also fail the hot needle test.
Remember, Jasper identification is restricted to two primary properties, the stone’s hardness, and opacity.
