4.0 x 3.4 x 2.9 cm. Truly complete stalactite clusters from the classic Ray Mine are uncommon. This piece is a particularly aesthetic miniature, complete all around, with surreal "reaching" stalks that are translucent and slightly curving as they reach out from the matrix base. This would be an older specimen, from the 1970s or early 1980s. Most specimens from the modern finds here just look different, and also tend to consist of smaller stalactites on larger matrix. It is interesting how the quartz coating on the chrysocolla "dimples out" at the tips, creating a clear translucent cone atop each stalactite.
