The Fuentes de Ebro quarry in Spain produces world-class gypsum specimens and this one is no exception. Two, gorgeous, water-clear fishtail-twinned selenite crystals are boldly upright on snow-white alabaster matrix. The large crystal is 2.9 cm. This beautiful and aesthetic specimen is from the Marty Zinn Collection. Old material from the early 90s, late 80s...not available today! Valued highly, in fact, now that they are gone.
