This is an excellent and current video on pegmatite pockets by Tom Campbell, Staff Mineralogist, The Arkenstone.
I’m headeding into pegmatite country soon and I will be on the lookout. Sobering statistics. Less than 1% of pegmatite rock hosts pockets and only 1% of that contains recoverable, intact gemstones.
Never-the-less, I always find something interesting when I am out in the field, especially in an area of complex geology.
On my last trip I found that rare granite and wonderful pyrite specimens in a black matrix (probably biotite rich schist) right along the side of the road. There was some pegmatite rock as well but of poor quality.
Who knows? I am going.
