Pyrite (excellent classic crystal group) (ex Kay Robertson Collection)

Item Description

Elba Pyrites are renowned for their superior size, quality, form and overall beauty. This thumbnail specimen is an excellent example of this classic material featuring a predominant, sharp, lustrous, soft golden metallic colored crystal with a combination of pyritohedral, octahedral and cubic faces associated with a few smaller Pyrites of equal quality. The piece is nearly a complete "floater", but there is a small contact on the back. I love the stark striation lines that can be seen on selective pyritohedral faces, which play nicely against the smooth, brilliant octahedral and cubic faces. A truly fine quality and attractive example of this world famous material. Hard to photograph, better in person. Ex Kay Robertson Collection (#5428). Kay was a prominent California collector, who specialized in European classics. She nearly lived 100 years from April 1920 - March 2020.
