I have or had some Topaz specimens that looked similar to that but with lesser striping on them. Rub the rocks with a finger or thumb and it it feels greasy, then it may be Topaz. Not sure what caused the striping on them but possibly a reaction to whatever mineral compounds the adjoining rocks were made up of.
Thanks Frank,it's good to hear from a fellow vet.I served in the Army from 1978-84,anyhow it's not really greasy feeling,I'm pretty sure it's smoky quartz I've just never seen this kind of striping on it before.
Hey 1etowah, I haven't forgotten you, but the weather isn't cooperating and the pics don't show right w/o natural light. Nuthin but rain rain rain... Yakker
