Nestled strikingly in a vug of ocherous limonite is a cluster of intergrown, lustrous and translucent, bright apple-green cuproadamite. The crystals reach 1.7 cm in length. Wonderful contrast in color and form makes these a classic, and the intense bright color is still unequalled in any modern finds here (this is probably from the 1970s or early 1980s) .
