Description
English: Spinel
Locality: Luc Yen, Yenbai (Yen Bai) Province, Vietnam (Locality at mindat.org)
Size: cabinet, 10.1 x 7.8 x 4.6 cm
Spinel
THis is a rare exmaple of a spinel twinned spinel crystal NEXT TO an untwinned crystal in close proximity. Such pieces are few! The large spinel twin here is 3-dimensional, fairly gemmy, and textbook-sharp in form. It is over 2 cm at longest width, at its bsae. The distorted, elongated octohedron next to it is just about 2 cm. This piece was expertly worked to excavate the crystals and leave them isolated on contrasting marble matrix - but you can see as how a mis-step during prep would have destroyed this unusual specimen.
