This is the largest specimen I have ever seen of this rare material often mistaken for the more common species cobaltian calcite, and it is studded with bright, lustrous, translucent, magenta-colored crystals to .5 cm. I must say that the color is the deepest I have seen for this species, as well. It is VIBRANT! And, for such a rarity, a real treasure. You could probably break it into pieces and make a good buck selling smaller samples fo rmore money per square inch.
