Lovely chart, it shows how much time you put into it.
Dalmatian Jasper is actually a quartz and classified as a siliacate. It's not a true jasper but close to the same qualities. It's mostly quartz and feldspar based with spots caused by tourmaline(dravite) and iron oxide. Yeah it's more correctly Dalmatian Stone, but jasper means spotted stone, so I say close enough.

Glad you like it!

Something can be silicate without being a quartz. If something is "mostly quartz and feldspar" that makes it a felsic rock -- possibly a rhyolite.

Lots of gemstone-selling websites misuse terms right and left, to the point where it can take a lot of digging to find any accurate information. So for this chart, I wanted to counter that by being as strict and precise as possible.

Ok I understand. I was just going by what my rock guy had told me when I was buying stones. But again as you stated with the websites, when they are looking to make a sale they'll tell you anything.

AWESOME. Thanks for this. I don't really draw gemsonas but its cool for me to have fun guessing what a single gem or gem fusion in the show may look like. Wow! Fireworks! lol
