Ethiopian opals originate from volcanic activity. All volcanic opal is called “hydrophane opal.” The term hydrophane comes from the Greek words meaning “water-loving” and describes their ability to absorb water and change from opaque or semi-translucent to translucent or transparent. Sometimes this highlights the color play – other times the opal will become transparent or opaque, with no color when hydrated. The color returns when the gem dries out.
It is important that you handle and clean your opal jewelry with care. Never use a steamer or ultrasonic, keep away from harsh temperatures or sudden temperature changes. Simply wipe your opal jewelry with a clean soft cloth.
The opal is a favorite gemstone of mine given its wide palette of colors, shapes and versatility in jewelry. I’ve created many pieces of opal jewelry over my 40-year career as a fine goldsmith. It also explains why we pride ourselves on having a wide selection of loose opals available to collectors and for custom jewelry orders.
