Euclase specimens from Chivor are in high demand and quite expensive. This specimen is from the 1981 find. The specimen consists of two crystals merging together at an acute angle. The color is a rich teal, green tinted blue which is hard to capture in an image and more attractive in person. The sides of the crystals are striated. The upper crystal is double terminated with one termination exhibiting recessed growth patterns. This termination is quite gemmy and transparent. One side of this crystal consists of cleavage planes. The other crystal is blocky and has a contact area at one end with casts after no longer present smaller crystals. There are a few internal fractures and some small chipping/wear on some of the edges. A thin line of micro Pyrite crystals runs through the specimen near the base of the upper crystal.
