Summary edit

Description
English: Cookeite
Locality: Barra de Salinas district, Barra de Salinas, Coronel Murta, Jequitinhonha valley, Minas Gerais, Southeast Region, Brazil (Locality at mindat.org)
Size: cabinet, 10.5 x 5.5 x 4 cm
Tourmaline in cast of Cookeite after Tourmaline
Like the above specimen, this is an important tourmaline specimen because so few of the multicolored scepters from this famous mine are on any kind of matrix, let alone so appealing and aesthetic a matrix as this one! Also, it has NO repairs. The GEMMY red/green zoned tourmaline crystal, which is doubly terminated, measures 6 x 3 x 2.5 cm and perches gently in the hollowed-out cast of a larger previous generation of green tourmaline. In person, it is really quite a bit more colorful and gemmier than it appears, and the contrast to the yellowish-white cookeite is striking. The upper temrination is freestanding and complete, etched as most BdoS tourmalines are but nevertheless showing a beautiful and colorful tip. Note that the BOTTOM termination of the tourmaline is also fully terminated in a series of trigonal stepped prisms, which is quite obvious in person. The cookeite does not fully cover the tourmaline shell, now hollow, of the original green tourmaline which encloses the new tourmaline. This is also more apparent in person. Lastly, note that in good lighting this can glow with much more color (top photo). Oh, and it is Complete and undamaged! This specimen comes with a custom-made lucite base.
