Extracting Gems from Host Rocks

Recommended Posts

Wondering how gems are extracted from host rocks. Can't find anything on this on the internet.

I occasionally find what I think is a small black tourmaline crystal embedded in quartz. I think some of these might look nice if I could get them out of the quartz. I know hydrofluoric acid dissolves quartz, but I'm afraid that it'd take the crystal with it. I did a google search on getting gems from host rocks, but youtube and google seem to be empty on the topic. I found a line that after the rock is milled, it is spun around in a water solution and then that will erode the stone and leave the gem.

Besides all the hand tools to persuade bauble from matrix, I would assume they're dug out from surrounding matrix by diamond saw/drill/grinder-cutting away what you don't want... THink Dremel but more industrial.

Here's a pic of a portable diamond saw for field use- just a Makita tile saw.
