• Lot Description
  Including:<br> Dark Opal Nodule with Multicolor Play-of-Color<br> A rounded dark-toned opal nodule displaying scattered flashes of red, green, blue, and orange across its surfaces. The top reveals a textured “crocodile skin” pattern characteristic of partially weathered opal, with bright color patches visible through the natural fractures and seams, 1". <br> Ethiopian Honeycomb Opal<br> A vivid piece of hydrophane opal showing the classic “honeycomb” pattern—hexagonal cell-like structures that illuminate with electric greens, oranges, yellows, and fiery flashes when exposed to light. Highly translucent and strongly reactive to moisture, this specimen displays exceptional color play typical of Ethiopian Welo opal, 3/4". <br> Boulder Opal in Ironstone Matrix<br> A matrix opal specimen retaining its host ironstone, with a wide vein of bright blue and green opal cutting through the surface. The color band shows excellent depth and vibrancy, contrasting against the rough, tan-brown matrix typical of Queensland boulder opal fields, 1-1/2" x 1-7/8". <br> White Opal Seam in Light Matrix<br> A pale white to cream-colored opal piece featuring broad, shimmering patches of pastel play-of-color—greens, pinks, oranges, and violets—emerging from a soft, chalky matrix. The seam-style formation suggests origins consistent with South Australian white opal deposits, 2" x 2-3/8".<br> A small, polished boulder opal cabochon displaying a vibrant ribbon of color play set naturally within its ironstone matrix. The oval-form stone shows a warm, earthy host rock with a narrow but intense vein of opal flashing bright greens, golds, and occasional orange fire under direct light, 9/16".
