Meet John & Jackie,

Our Bull Creek Boulder Opal Dangle Earrings from Our 2023 Line, “The Rainbow Collection”

Two halves of a natural split, these Australian black boulder opal earrings vividly display all colors of the spectrum.  While they especially pop in direct, bright light, play of color can even be seen in low-light conditions.  Boulder opal is the more durable of opal varieties.  This particular stone is part of a new find, discovered in the Bull Creek Mining District of Western Australia during the year 2021.  The rough material was then cut in the end of December 2022.  These earrings were handmade in-house and dangle an impactful length 2 inches.

    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.
