Quite simply one of the very best thumbnails I have ever seen form the locale, over many years. The large crystal is just about an inch, and 1.8 cm wide. The color is astonishing. This is probably one of the older specimens found, dating to early mineral collecting here in the 1950s and 1960s. It is phenomenal for the richness of color, the luster, and the sharpness of the crystal. I have never seen the like in any size. Euclase form other locales is more gemmy to be sure, sometimes, but never more intensely blue! 2.6 x 1.9 x 1.8 cm
