This is a doubly-terminated floater of a spinel twinned copper crystal, measuring 4.0 cm in length. The crystals have a patina colored a rich brownish-red (untouched by acidizing). Classic Champion Mine style, in this cute miniature. Note that many of these on the market are brightended by acid wash, but this remains in its natural patina and color.
