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."
