There is a guy who sells rocks in general (i'll try to relocate his adee - I lost it off my computer in a recent crash but may have a invoice from him). He inherited a bunch (I mean a ton or more) of great Obsidian rocks and has to move them for lack of storage space. his price is outragous (low) and myself and a number of folks that I told about him, who ordered from him, were very pleased with the quality, quantity (extra fair), and service. I'll get back after I look. If not, perhaps one of the guys I told still has his adee, or web site info.
