Just thought I’d share this neat example of pleochroism. It’s a sapphire crystal from Madagascar which I just recently noticed is considerably greener when viewed edge-on. This isn’t unusual with corundum (and quite a few other gemstones for that matter), but the color difference here seemed striking enough to make a little post about it. #sapphire #crystal #pleochroism #geology #rockhound #fossicking #gems #gemstone #dichroic #corundum #gemrough #mineralspecimen #madagascar https://www.instagram.com/p/Bv64WQ-AfK_/?utm_source=ig_tumblr_share&igshid=joh4proeorv -- source link
