I hand cut this wonderful, rounded oval bead out of a lovely variety of black moonstone rough from Madagascar! It's more of a dark grey than black, but people call it black moonstone. This piece has tinges of almost pink to it as well. It measures 46x18mm and is 9mm thick with a 2mm drill hole. Weight is 59cts. Low rounded faces and edges. It has a really nice polish and great orientation in it's adularescence with patterns like one never sees in moonstone. This is one of the nicest pieces of moonstone I've ever cut!
I found a small amount of this never before seen rough when I was in Quartzite in January of 2011 and I bought ALL the good pieces of it available! It's called "black moonstone" but I call it "Black Lightning Moonstone" because of the INCREDIBLE PATTERNING! This massive dark moonstone feldspar comes in large crystals that are riddled with included healed fractures that resembles a WEB of lightning bolts throughout! The included fractures were completely healed by Mother Earth millions of years ago, but the chatoyance and adulaurescence of the moonstones bounces around and off of the fracture lines to INCREDIBLE EFFECT. It has a really nice polish and great orientation in it's optical effects. This is one of the nicest, most unusual, and dramatic pieces of moonstone I've ever cut! You won't find material like this from any other lapidary artist!
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."
