Well, they’re not Windstones, but they do say that the occasional off topic post is allowed, and I’m trying to find a new home for these without having to pay ebay fees, so…
Three polished Labradorite slabs for sale! Labradorite is a form of feldspar that has what’s called “chatoyance” or sometimes just “flash.” It’s like moonstone, and also a bit like tiger’s eye, both of which are also chatoyant. What that means is that it has a optical property that causes colors to come and go depending on the angle you view them at. I tried to capture this in the photos below. All three of these are quite nice, though one of them has a much stronger flash than the other two. (And is priced accordingly.)
Slab #1 $10
Slab #2 $9
Slab #3 $15
Shipping is $3 for first class or $5 for priority in the USA. International people will have to drop me a line for a shipping quote.
Anybody interested can PM or comment. Questions welcome!
