Fordite cabochon, (aka Detroit Agate) NOT an agate. The original material was created many years ago at the Ford Rouge Plant just outside of Detroit, Michigan. Layer upon layer, paint over-spray built up on metal racks that transported new car bodies through the paint shop, and into the oven, where each coat was baked hard.

18 Various Kinds of Opals
When most people think of an opal, they might think of a milky-colored stone containing a rainbow of stripes or flecks inside it. What many people don’t know is that they are incredibly diverse in appearance, and are not actually minerals. Opals are a solid, amorphous form of silica, and are classified as “mineraloids”. Like other mineraloids, such as amber, pearl, and obsidian, they lack structural order, or “crystallinity”.
From the top:
- Black Opals
- Cat’s Eye Opals
- Dendritic Opals
- Flamingo Opals
- Peruvian Pink Opals
- Zebra Opals
- Leopard Opals
- Yowah Nut and Koroit Opals (both have the same characteristics - they merely come from two different areas).
- Brown Opals
- Ethiopian Honeycomb Opals
- Green Opals (Serbian, Tanzanian, and Brazilian)
- Peruvian Blue Opals
- Matrix Opals
- Landscape Opals (Andean and Australian)
- Mexican Fire Opals
- Crystal Opals
- Australian Boulder Opals
- Ethiopian Ribbon Opals
(Side note - the image backgrounds are transparent, except for the matrix/landscape picture, which seems hellbent on being an asshat, no matter how many times I try to fix it)
The Mineral Moon (NASA/JPL)
"This mosaic of 53 images was recorded by the Jupiter-bound Galileo spacecraft as it passed near our own large natural satellite in 1992. The pictures were recorded through three spectral filters and combined in an exaggerated false-color scheme to explore the composition of the lunar surface as changes in mineral content produce subtle color differences in reflected light."
