Cobaltoan Calcite (Pepto pink) , South Africa
Ammonite pair polished, Madagascar
Citrine Quartz cluster, likely irradiated for color change from amethyst, from Brazil

Second Picture – Quartz Crystal Cluster, Arkansas
Almost impossible to get a quick “snapshot,” challenging to photograph, tabby quartz and complex crystal form cluster from Arkansas,. Has separation breaks on one end (from vug wall) and hidden break on other end, but dominant crystal on that end, ends in many pyramid points on one termination. Also, this cluster has at least 3 showy sides, no top or bottom to it when lying on it’s side. Many different termination types, very complex and beautiful.

A Banded Agate With Surrealistic Distortion

Agate

This agate may have been distorted by movement when it was still in the gel stage, giving it this cool “melting” surrealistic shape. The same visual effect of distortion can be created by cuttting/grinding a curve on the surface of the agate, but this one appears to have a flat cut surface.

Red Agate

Red in agate is usually caused by iron oxides. The dinosaur bone is a replacement by agate, colored, in part, by iron oxides in the agate material. Fire agate is even more directly affected by iron, as it causes all the iridescent colors.

Fire Agate FLickr Big Red

One of the most popular agates for collectors is Lake Superior agate, which is usually red with clear, white, brown, and/or black banding. Sometime it’s gray, and other colors and patterns occur.
