Chinese writing stone is a naturally occurring gem that is actually mined in the foothills of the Sierra Nevadas in California. Those who discovered the stone felt that the white crystal structure against the black stone looked like Chinese characters, hence the name Chinese writing stone. The majority of the stone is limestone, and the white flecks are andalusite crystals. Porphory is a second name for the stone exists which is rarely used in trade, though perhaps it is more PC. This gem is a recent discovery as rocks go. It was discovered during highway construction in the 1960's. It's beauty and durability make it a fantastic stone for jewelry making. It is a 5-6 on the Moh's scale of hardness, which makes it a reasonably tough stone. It is thought that Chinese writing stone is helpful in making a person dream. Pretty cool! Try sleeping with this ring on!
