Sphalerite- Gem crystal
stock #18.AX- 161
ZCA Mine number 4, Balmat, Balmat-Edwards District, St. Lawrence, Co.
1.2 x .8 x .4 CM (thumbnail)
A small, gem clear single crystal of amber colored Sphalerite. Complete and undamaged from the remarkable finds decades ago at the ZCA (Zinc Corp. of America) mine in Balmat, NY. A "textbook quality" crystal, despite the small size this has good eye-catching luster and color.
Beryl var. Emerald wih Quartz
Mina Amarillial, Cosquez, Municipio de Muzo
5.4 x 4.8 x 2.6 CM (cabinet)
A two-sided specimen holding dozens of light to mid green Emerald crystals that are intermixed with Quartz crystals. Very unusual for a Colombian Emerald specimen, the usual association in Calcite. Prior to our finding this material the only Quartz matrix I have seen or know of for Emeralds is at Penas Blancas and it is very rare there. This little known cut near Coscuez has now produced a few of this rae combo. A choice and rare piece with many small, very clear Emeralds covering both sides of the matrix. With magnification the quality really stands out.
