Eulytine occurs in Late-stage crystallization of bismuth-rich hydrothermal quartz veins. Usually in gemmy red-brown to green crystals to several mm in vugs. Crystals may be individual complexly modified tetrahedra, but rounded crystal forms are common. Clusters of crystals may be composed of a few individuals or may show only the projecting apices of tetrahedra and in extreme cases nearly smooth spherical clusters. Also commonly occurring as globular aggregates.
Chrysocolla is a soft and fragile material. Much of the chrysocolla used in jewellery consists of very attractive cabochons of green or blue chrysocolla impregnating either rock crystal or opal. Chrysocolla is often found in a matrix of quartz, in which case the optical and physical properties may be closer to those of quartz. Chrysocolla covered by druses of small sparkling quartz crystals is called "Drusy Chrysocolla" and is very popular for jewelry

Eulytine occurs in late-stage crystallization in quartz bismuth-rich hydrothermal veins. Named from the Greek for good and dissolved, in reference to its low point of fusion. Usually in gemmy red-brown to green crystals to several mm in vugs. Crystals may be individual complexly modified tetrahedra, but rounded crystal forms are common. Clusters of crystals may be composed of a few individuals or may show only the projecting apices of tetrahedra and in extreme cases nearly smooth spherical clusters.
