Ahhh, thanks! Question: do red stained quartz count as red quartz? or is that a different thing?

Well yes, red quartz is red because of inclusions or a thin film of iron oxides. I suppose "red quartz" might be just a casual name for it. Here's a neat example of amethyst being covered by hematite inclusions. You can't even tell it's amethyst because it's entirely reddened by inclusions: www.mindat.org/photo-184661.ht…

wow, that's so red! Anyway, I was asking that because I once saw a little red crystal for sale, that was a little bit too expensive, they said it was red quartz from Spain, and I was wondering if my little red stained quartz was the same thing just with a little less inclusions as it's not that red, or if it was a totally different thing. Telling what crystals are is not that easy!

Oh yes! I just happened to come across this now. I thought you might be interested: www.e-rocks.com/Products.aspx?…

Here's some really good red quartz from Spain. If you're up to it, you can bid for it, as it's an auction item.

Actually, there's a name for red quartz: eisenkiesel (see: www.mindat.org/min-9250.html) .

I suppose the price of that Spanish quartz really depends on how much inclusions there are. If there's not enough inclusions, you can just call it ferruginous (iron-rich) quartz (see: www.mindat.org/min-27246.html) .

Did you happen to see Spanish quartz that looks something like this?
