mighty interesting stuff in those photos, love the OJ and the rutile quartz, the blue in the banded stuff is almost shocking! What makes it blue? Always love to see the local material as well. Outside your garage looks just like mine! Staying inside and having hot cocoa today. (30 below wind chill predicted with warnings). Thanks for the show!

Your finds took a good shine. But I also like OJ.

What makes it blue, I should have known & been prepared with an answer for ya Deb!! But- since you have all that free time on your hands I'll leave that up to you to add to the list of research topics I'm gonna throw it in for another 24-48 hours of grinding, it goes pretty fast in the grind and when polished in places is taking a fantastic shine - probably need to go with more plastic beads in the next batch to avoid the bruising. The smaller rose quartz I had in the batch from stage 2 on had been polished previously and came out nicely shined with no frosting - so it could just be this particular material - we'll see. I was surprised by how clear & shiny the rutile quartz came out given what it looked like to start.

Blue is usually copper.
Except in rocks that are just blue like lapis lazuli.
Could also be aluminum as in dumortierite.

shotgunner that checks with what I was able to find. quartzite with dumortierite, also sold as blue banded aventurine quartz (to keep us from thinking it is feldspar quartz I guess. Interesting stuff.

Back in the day (late 80s or early 90s) I was told this blue-banded quartz was called blue aventurine. Is that a legit alternate name, or was I misinformed? Nothing would surprise me, as my sources back then misidentified many of the stones in my collection. I found another batch that I would like to tumble soon and it would be nice if I knew the right name. I hope to shape on the wheel and then finish in my rotary tumbler...
Edit: OK, now I saw the comment about how it was also called blue-banded aventurine quartz...OK, good! I have a name and a plan...

Edit: OK, now I saw the comment about how it was also called blue-banded aventurine quartz...OK, good! I have a name and a plan... peachfront, it would seem from what I read that blue aventurine quartz is a market name for the stuff, since it is by nature quartz, and aventurine in its proper form is a feldspar. So if you have the stuff pictured above, it is blue quartz, marketed as blue aventurine quartz, but not blue aventurine which is something different.... yeah, who's on first, right? nomenclature is always not 100 percent since science varies, scientists disagree, let alone every day enthusiast type people who do a lot of identifications in this hobby, market and regional names abound. how could we help but misidentify so many things? Scientific analysis is not always available so a lot of time it is up to "best guess". " A rose by any other name"... and all that.

I eagerly await the results of your blue banded quartz. Bought some from The Rock Shed, (they call it blue quartz). I have some that I'm tumbling now (been in there since late December), and it's not taking a shine like I thought it would. I'm not going to give up on it!

I previously polished this material in I want to say 1994 or thereabouts in a Lot O. It does take a great shine. But I have not worked it in a rotary before, and obviously I went many years without doing any tumbling so...it will be interesting to see how it works out.
