NOTE:
This is a thin crystal opal.... you can see right through it. Nice fire..... but the blue color in the pictures is caused by the light used. As I said, clear, with flashes of color when moved under bright light.

This is opal from the welo district of Ethiopia. Opal is a hydrated amorphous form of silica, with a water content of about 5 to 10 percent usually. Opals are one of my favorite gems due to their beauty. But, they must be afforded some care to maintain that beauty. About 6.5 on the moh's scale, they should not be subject to harsh abrasion, and because they absorb water caution should be exercised. If you wear them when bathing, the fire may disappear for a while , but will return as the gem dries out. However. if the water is dirty, some impurities may enter the stone....so caution should be practiced. Opal is said to inspire love and passion
