Meet Wilma & Betty,

A Matched Pair of Patterned Boulder Opal Earrings

Cut from a near-perfect split of natural boulder opal from Koroit, Australia, the opals weigh 19.09 carats and measure 19.56 carats and are set in 14 karat yellow gold.  Veins of purple, blue, and green color run through the pair of stones.

The dangle earrings measure just over two inches in length from the top of the shepherd's hook findings, making these pieces fine statements to be noticed.

    About Opal

    While many believe opal to come only in a traditional white hue, this common misconception cannot be more inaccurate.  With over 200 varieties of natural opal discovered so far, the historically referred "Queen of Gems" can come in a wide variety of colors- before the stone's famous "play of color" rainbow effect is even taken into consideration.  Over 90% of the world's opal is produced in Australia with other well-known deposits located in Mexico, Ethiopia, Brazil, and the United States.

    Chemically, opal is an integrated combination of water and silica.  Water content in opal can range from 3% to 21% by weight, with average jewelry material ranging between 6% and 10%.  Because of this, it is advised to store your opal jewelry with care; safes and bank vaults can be notoriously dry.  We suggest storing opal in an airtight container along with a piece of water-moistened cotton when dry storage conditions are anticipated.  Some varieties are more resilient to harsh conditions than others.  It is safe to clean solid opal jewelry with warm water, mild soap, and a soft-bristled toothbrush.  Avoid chemicals, harsh abrasives, and ultrasonic cleaners.
