And a lot (most?) of the green in Petrified wood is from iron in specific low concentrations if I am recalling correctly.

Iron(II) Sulfate is a purely green salt of iron, completely devoid of any relation to copper, nickel or chrome. Is probably the source of green in Indian bloodstone, heated it turns red/brown. Anybody wanna send some bloodstone to jamesp? I haven't cut mine yet. But its the wrong color for vegasjames enigmastone. I think XRF data reported above may be in calibration error and more analysis is in order. I think that perhaps James has a softer than jade amphibole perhaps with potassium instead of sodium in the analysis...

I'll bake that sucka. But you will probably be in for a surprise. Brown sounds most probable. Especially if it is a formation in volcanic origin-is bloodstone from such ?
"Bloodstone, sometimes called Blood Jasper in the trade, is not quite a jasper but rather a dark green Chalcedony which is a cryptochrystalline variety of Quartz, and which contains inclusions of red to brown. Although the color is not consistent, the red spots are caused by iron oxide and the green color is from chlorite particles or Hornblende needles."
hornblende alters easily to epidote and chlorite(wiki)
Heating bloodstone will release it's chakra(BS)

snowmom chlorite is a form of mica and is very soft. This is really going to need vegasjames chemical analysis to sort this out further.

New data from the XRF friend. I think it's part of the samples. No silver jewelry. I asked why can't the silver be present in both samples? The green stone is from Nevada, The Silver State for gosh sakes! And then a followup answer vegasjames - maybe we should talk. Beryllium is between Hydrogen and Neon (as are carbon, nitrogen, boron and others). Huge money in Beryllium. You said this is also geographically nearby to the Nevada Tiffany stone? Both samples need to be checked. Maybe we can work together on that. You have my number if you are interested.

Might be a Nepheline with Potassium Feldspar. There might be a Zoisite component as Nepheline often alters or partially alters to Zoisite.

This Nepheline var Tinguaite cab looks pretty similar to some of your stuff vegasjames. There's an aegerine component to this material as well.

It does look a lot like zoisite but I read it is brittle and this is not. Zoisite also gives a white streak and Scott was saying my sample gave a light green streak. Hopefully I will have the analysis back from the lab soon so I will know the exact chemistry.

Nephiline has aluminum, conspicuously absent from this sample. Zoisite same story. Orthoclase, microcline, sanidine and adularia also possess significant aluminum. You input is indeed valued. Thank you. Please keep thinking and sharing ideas.
