Fluorite
Fluorite (calcium fluoride), historically called Fluorspar, has been used in carvings and decorative objects for hundreds of years, but the availability of faceted pieces is a relatively new development.
Fluorite is 'the most colorful mineral in the world' as it comes in a bouquet of sparkling colors accompanied by glossy luster. The word fluorite originated from the use of the mineral as a flux in steel and aluminum processing.

Fluorite, a transparent and translucent stone which mean 'to flow' in Latin. The term 'florescent' also has been derived from fluorite.
Fluorite (also called fluorspar) is a mineral composed of calcium fluoride, CaF2. It is an isometric mineral with a cubic habit, though octahedral and more complex isometric forms are not uncommon.

fluorite
Also called fluorspar, it can be striped or spotted. Its color can be modified by heat or radiation. It derives its name form its ability to emit visible light under the influence of certain rays.

Fluorite occurs in many colors including purple, colorless, red, pink, yellow, green, blue, black, yellow, and multi-colored stones. Crystals are transparent to translucent. Fluorite is relatively soft and easily scratched limiting its use in jewelry.
Fluorite is a mineral that comes in a wide variety of colors. Because it is relatively soft, it is often carved into figurines, bowls, eggs, spheres, and various decorative objects.

Fluorite at 4 is not twice as hard as gypsum at 2; nor is the difference between calcite and fluorite similar to the difference between corundum and diamond. An absolute hardness scale looks a little different than the relative scale.
This stone is known as opalite, ice cream opal, opalized fluorite and opal fluorite. The name Tiffany Stone presumably comes from the jewelry company of the same name that used it in some of their designs.
Online research tells us its composition is most likely fluorite in quartz or agate. However, as with many imported stones, descriptive names often stick in the marketplace before the true mineralogy is sorted out.
