A matte finished, wedge shaped, focal bead made out of a rare kind of Porphyry from Australia, with BIG PINK INCLUSIONS OF FELDSPAR! Also known as Chrysanthemum Stone, Chinese Writing Rock, Calligraphy Stone, and porphyritic granite. I hand cut this piece, measurements are in mm in the listing title, and it has a 3mm side drill hole. I like to leave this material with a soft, satinny matte finish. It has a wonderful feel to it and the grain of the stone doesn't take a super high polish. I think not trying to polish it enhances the pattern and the tactile nature of the stone.
The "classic" version of this material has white phenocrysts on a dark blackish base and is from an old source in Northern California that I heard was uncovered years ago when they were constructing I-80. Rockhounds swooped in and recovered what they could before it all got paved over. I don't know of any actual collecting sites in the US which are still producing any kind of quantity of rough, although random specimens are found throughout the NorthWest, and I have a few chunks of Australian rough. The phenocysts are what make up the inclusions and can form in all sorts of patterns. Technically this stone is called a "porphyritic granite" and variations of this granite are found all over the world. A really stunning and unusual stone much loved for the random beauty and stark contrast of the patterning
New Age Gemstone expert Melody says in her book "Love Is In the Earth" that Chinese Writing rock "is an excellent stone for dreaming, assiting one in dream states..." and "It is a stone for re-affirmation, re-alignment, and re-commitment."
