Huge! 11.29 carat untreated Sphene

This collectors sphene is amazing! The size of this piece is incredible measuring 13.2mm x 12.5mm x 8.4mm, and it displays a bright yellow green hue that shifts color dominance in different lighting. It features cross hatched crystal structures with a flawless superior luster that glistens across every well cut facet. This is an unheated example sourced from Madagascar.
