Natural Opal

When natural opal shows a play of colors it is known as precious opal. Precious opals are rare in nature and have been highly prized by man for thousands of years.

Here at mineralminers.com, we do not have any lab-created opal, we only have real natural precious opals that formed naturally inside the earth! Precious opal is still being mined today at several locations around the world; the most famous are mining areas are in Australia and in Ethiopia.

Ethiopian Opal

We specialize in 100% natural untreated real opal that was mined in the Ethiopia!

The recently discovered opal deposit near Delanta in the Welo Province of Ethiopia is producing very stable jewelry grade opal with amazing bright plays of green, red, blue, and orange colors in beautiful patterns. This Ethiopian opal is completely natural and has proven to be just as hard and stable as fine Australian opal and Brazilian opal. The body color of this natural Ethiopian opal ranges from golden-brown to white to colorless to blue, and the transparency varies from translucent to crystal clear. The transparent Ethiopian opals with color play are sometimes called jelly opal or crystal opal with beautiful flashes of color inside. Some of these natural Ethiopian opals tend to absorb water and change their transparency and colors if placed in water, and then they recover their original play of color and transparency after being removed from the water and drying out. This type of natural opal is known as hydrophane opal.

We are offering a hand-picked selection of wonderful 100% natural Ethiopian opals set into handcrafted one-of-a-kind real opal jewelry designs! They are so beautiful - be sure to see them!

Right now, we also are offering natural raw opal pieces in a variety of sizes and qualities including some Ethiopian opal gem rough specimens that will yield beautiful flawless precious opal gemstones!
