This rich Euclase specimen is composed of lustrous, translucent to gemmy crystals with what can only be described as the classic and vibrant blue that simply screams "Euclase". The largest of the crystals is about 1.6 cm across, and the sharp, fine striations highlight the glassy luster. Specimens of this quality came out in the 1960's to 1980's, and good ones such as this are hard to come by. Almost extinct on the market, in fact, they only come out of old collections!
