Copper ("Spinel"-twin)This is a classic example of what a "Spinel" twinned Copper should look like. The piece has a beautiful mixture of the elongated form of the twin itself which plays beautifully against the smooth outer octahedral crystal faces. If you look to the center, you will see the concave "channels" that run the length of the specimen, these are essentially the contact planes where the crystals are twinned together. The piece is doubly terminated with no damage

Some of the crystals are broken

There are hundreds of Kunzite specimens on the market from Afghanistan

the term copal comes from the Nahuatl / Aztec word "copalli" which translates into "incense"

Specimen # BOL711B247

The specimens are reminiscent of those from Lincoln County

A full-sized thumbnail of Amazonite with good medium blue-green color

The contrast of the satiny white Hopeite with the light blue-green Phosphophyllite sitting on the reddish-brown altered Sandstone matrix makes for an eye-catching specimen

The Siderite from this mine ranges in its chemistry from the far iron end to an iron/manganese mix

I have photographed these strange Quartz crystals under the microscope to better illustrate their quality
