I hand cut this lovely focal bead out of natural moonstone from Australia and the miners call it "Lunalite". Measurements are in the title in millimeters and it has a 1.8mm drill hole. This is a variety of Moonstone with orthoclase veins running through it which is found in the same location as the Rainbow Lattice Sunstone surrounding the Utnerrengatye Mine. Moonstone is a variety of feldspar that has an optical phenomena of adulaurescence, similar to labradorescence.
Here's a video showing a Tanzanian sunstone, this moonstone, and 2 astrophyllite beads...

I've copied the wiki definition of moonstone below for your information. That is followed with a bit of info on the metaphysics of the stone.
"Moonstone is typically a potassium aluminium silicate, with the chemical formula KAlSi3O8."
"The most common moonstone is of the mineral adularia. The plagioclase feldspar oligoclase also produces moonstone specimens. Its name is derived from a visual effect, or sheen, caused by light reflecting internally in the moonstone from layer inclusion of different feldspars."
"Moonstone's delicate beauty and its long heritage make it perhaps the most familiar gem quality member of the feldspar group. Moonstone is composed of two feldspar species, orthoclase and albite. The two species are intermingled. Then, as the newly formed mineral cools, the intergrowth of orthoclase and albite separates into stacked, alternating layers. When light falls between these thin, flat layers, it scatters in many directions producing the phenomenon called adularescence."
"Deposits of moonstone are found in many countries and places: the European Alps; Brazil; India; Mexico; Myanmar; Madagascar; Sri Lanka; the USA, specifically Pennsylvania and Virginia; and Tanzania. However, it is Sri Lanka that produces the highest quality moonstones."
and from a different source is the following information... "Mystic Lore: Intuitive sources say that Moonstone is a stone of emotional harmony and wellbeing. It has been revered for centuries in India as a stone which can bring harmony and good fortune to marriages and love relationships. Moonstone is said to help one relax and enjoy life, and to help one fully love & appreciate others."
