Slate-- you said you used it

Dear Australian… You said you used slate… I was just curious
as some one won an award using slate in a triangle and then a
gold ring in the center I do believe it was in the last
Lapidary Journal… It was beautiful… So I wondered how it was
cut and where on procured it…But reading about the answer in
your letter I don’t think I shalll bother… Thanks anyway
