This is a very unusual and very expensive form of platinum: Fine ultra-pure woven platinum cloth. (Like mosquito netting only more expensive.) .Greg sells this stuff and he very kindly donated a sample: This is way, way more expensive than I could possibly afford for an element sample (about $1100 a gram). He also sells lots of other unusual elements on eBay: Check the source link for more information.
I chose this sample to represent its element in my Photographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of.
