Some of the best color Sphalerite in the world comes from Spain. A large percentage of the stones that come from Spain are on the warmer end of the spectrum, but rarely does one find a stone with a distinct green color like this from Santander. This stone has very good dispersion, color, size and excellent cutting. The color of the stone is a combination of green and yellow, and faces up to show a splendid array of color. This stone is amazingly clean for this material as it is very hard to obtain totally eye clean stones from this area. I would say the gem is very slightly included, but when you find a stone this color with this clarity, and in this size, it is a real treat. I have a hard time finding this color of Sphalerite from Spain, especially in this size. The cut on the stone is a Trillion Brilliant. Make sure to take advantage of this opportunity to own an attractive, good size, beautiful rare collector stone.

Nestled atop a curving vug of sulfides is a superb, lustrous and translucent, complex fluorite crystal measuring 4 cm across. Thep astel green crystal is associated with lustrous, black sphalerite crystals to 1 cm across. A druse of tan colored calcite partially coats one face of the fluorite crystal on the backside but it is actually freestanding and complete, all around. The fluorite fluoresces a deep purple and the calcite fluorescence is a terra cotta color. This is a classic Naica fluorite of old style, with stepped faces. The colors are subtle and hard to capture accurately on these -in person, it is more a pastel green
