<<< BACK TO LIST SOLD Dioptase, Calcite, Malachite Cuprite etc. Christmas Mine, Gila County Arizona, United States 9.5 x 6.4 CM (cabinet) price: $360 This is the best, brightest and most attractive Dioptase I have seen from the Christmas mine (best known for its Kinoites). It is a feast under magnification with bright slender crystals and lots of colorful associates set off by gemmy Calcites. Ex Mike Shannon Collection, this is in excellent condition damage wise (none!) and the color is much more intense than the monitor shows. Eye catching display quality.
