Twinned Calcite is one of the most visually striking materials in the gem world - the twinning planes causing intense dispersion to be visible. No stone is capable of the same level of full color flash These are typically best when colorless, otherwise the dispersion is usually masked; this stone however, combines these two characteristics in a mesmerizing and beautiful display. You have both the wild visible dispersion of spectral color as well as a fine orange bodycolor. The tone of the orange is just right to give the stone color, but not detract from the dispersion; the combination is so intriguing that it almost looks like a large Mexican Fire Opal with play-of-color. Moreover, it is a larger piece so it is quite dynamic and impressive in-hand. As if this were not enough, the stone is actually a true bi-color with a distinct orange/colorless separation visible when face-down. Face-up it is almost imperceptible as the twinning and strong doubling blend the color. A beautiful collection gem that has been given a precision US cut to best show off its visual appeal. Remarkable stone.
