Welcome.
This is a 'Family' of 12 Octohedron Fluorite Crystals. These were obtained directly from a representative of the mine where these were harvested in China. The pastel shades are from clear to very light lavender to lavender to sea green. The smallest crystal is 0.3 inches across side to side (not diagonally) and the largest is 0.75 inches across, with varying sizes in between those two. Their combined weight is 2.75 ounces.
The finest formed octohedrons of fluorite come from China and this family is no exception. They are semi-translucent allowing light to pass through. They are raw meaning they have not been altered from their condition in the field.
Please feel free to message me with any questions, and Thanks for looking.
