More About Our Opal from Around the World

Our primary source of opal has been Australia up until 2008 when a new supply was discovered in the Welo province of Ethiopia. This new material is a hydrophane opal that can absorb and release water making it less inclined to craze which happens to many opals as they loose their water content. More durable than Australian material this opal is available as white opal, crystal opal and occasionally black opal. The high transparency of much of this material allows us to facet it giving unique and unusual gems. Intense colors and high clarity typify this lovely opal. These are some of the largest opals we have ever owned. We have recently purchased a small lot of orange fire opal suitable for faceting and cabbing. The sizes are unusually large.

Ethiopian Opal is the perfect gemstone for elite clientele who appreciate dynamic beauty and geological rarity. Harvested from volcanic highlands in the Wollo and Shewa regions of northern Ethiopia, these opals captivate with vivid play-of-color—flashes of red, blue, green, and orange that sparkle like captured rainbows. Discovered in 2008, Welo opals have quickly emerged as a standout choice for luxury designers seeking modern masterpieces that merge artistry with nature’s brilliance. Unlike traditional Australian black opals, Ethiopian Opal offers transparent-to-translucent clarity with an ethereal, water-clear base that allows light and color to dance openly within. Each cabochon becomes a living canvas—perfect for bespoke rings, one‑of‑a‑kind necklaces, and statement earrings that turn heads with every movement. These stones bring a fresh, contemporary elegance to high-end collections and appeal to collectors seeking something both visually stunning and narratively rich.
