Calcite and Quartz

[rockpic]

I see quartz is on the minds right now, here is one I dug out this summer.
Not nearly as big that Barrett is showing. LOL
But a fine specimen for my display case. Its from the Monty lake area, BC.

very nice

[Barrett]

Yes, this is not a bad find. I have seen this pic already. Did you stumble on this spot/specimen or was this a spot folks collect at to begin with?

[rockpic]

Yes I,m sure you have seen this one. Posted the same pic on another forum recently that has a little more interest in mostly one type of gem, you frequent in and out.
No its from our claim in BC. Not a public site.
Have you seen the colored drusy quartz we pulled this summer? Nice stuff. Closest to purple I'm going to find.

That specimen is beggin to be soaked in SIO! Nice find!

Thanks Scott, New to these terms just want to make sure I understand it.
SiO solid as yellowish-brown in color and as being an electrical and thermal insulator. The solid burns in oxygen and decomposes water with the liberation of hydrogen. It dissolves in warm alkali hydroxides and in hydrofluoric acid. The heat of combustion of SiO to be 200 to 800 calories higher than that of an equilibrium mixture of Si and SiO2 (which could, arguably, be used as evidence that SiO is a unique chemical compound), recent microscopy and spectroscopy studies suggest that amorphous solid SiO is best considered as an inhomogeneous mixture of amorphous SiO2 and amorphous Si with some chemical bonding at the interface of the Si and SiO2 phases

So what may give this quartz-agate the color red, may be the possibility of hematite for its color?

SIO on this board means Super Iron Out. A commercial grade acid/rust remover found in powder form at your area hardware store. Would make that specimen Pop with a capital P
