Beautifully nestled in a vug is a well-formed, large, 3-cm , crystal of lustrous, cherry red, rhodochrosite . It is translucent to transparent , mostly the latter. It is even doubly terminated with a sharp prism atop and a flat basal termination on the bottom. In fact, given this, it displays just as nicely on a horizontal viewing, with the dt-crystal perched atop the knoll of matrix. Its just harder to photo that way for some reason. This is certainly a piece that can be said to be among the top rhodo miniatures found at Uchucchaccua, and for its style is a unique specimen 3.3 x 3.1 x 2.7 cm
