I've decided to call the stuff "BC BLUE". these are only taken to 120 grit on the diamond so far but I wanted to show the shading and look of the rough before processing. This is only a couple of the variations of the colours available of this. Attachments:

thanks Cathy; I really like the softness of it too, I think it is caused by the background green base. I'm pretty sure it is a metamorphically altered chert. It is has very little if any grainyness if any but I'm not sure what to call it. There is such a variety of colours and it is all translucent to some degree, even the black

I've been having a lot of trouble withe term chert and used to use it as a general term with the others falling under it and it looks like the wiki reference supports this so here it is. As to what form of chert I don't know what the BC Blue is but it is probably chalcedony en.wikipedia.org/wiki/Chert

The top two Are the "BC Blue" chalcedony, which so far I haven't found in a pure colour yet. I've only cut a hundred pounds of rock from this site yet. and only 10-15 of the chalcedony. The center peice seems to be a chalcedony, quartz, opal, with hematite? healing the fractures. The last peice is a hematite with inclusions of tiny sparkly metallic sparkles that give it an allmost schiller effect. I was at the site yesterday and found some that is shot through with pinkish flourettes too, along with the red, that looks even more interesting. It is a harder hematite also and gives a decent polish. The peice is quite thin at the bezel edge; about a 1/16th " and has sharp clean edges so probably is silified too.
