The most exquisite miniature in the lot! This fantastic crystal is transparent and sharp as can be wished for, complete except for a small contact in the back. Aesthetically perched on a matrix of splendent, black sphalerite, are two equant, gemmy, pastel lavender fluorite crystals. The large one atop is about 3 cm across. The fluorite crystals are cubes modified by octahedral faces, classic for Naica.
