Featured here is a large18.49 carat cabochon opal that expresses a blue base with green red and blue flashes, This fine opal measures 19.4 mm wide, 21 mm long, 13 mm deep with a total depth of 67%. This Ethiopian opal has been cut here in our shop by precision gemstone cutter, Steve Moriarty, owner of our custom design jewelry store, Moriarty's Gem Art, located in Crown Point, Indiana USA! This opal gemstone has been sourced from Ethiopia. This is a fairly new source discovered in 2008. Ethiopia produces hydrophane opals, meaning they absorb liquids. This makes these precious opals resistant to a cracking that is caused by drying out, called crazing. If your opal gemstone gets wet, it will turn a milky white color. Within a couple of days the opal will dry out and its vivid colors will be restored. You will want to be cautious when applying products such as lotions, perfumes, hair sprays, hair dyes, etc.
