This crystal boulder opal from Queensland shows concentrated brilliant green fire radiating through its purple tinted translucent body. The center features an intense burst of emerald and lime green that seems to glow from within, while flashes of blue and pink travel across the edges. The colors are bright and saturated, creating a lively play that changes as you turn the stone in the light.

Measuring 13.8 x 8.4 x 4.7 mm and weighing 3.83 carats, this oval crystal boulder opal has a substantial feel with good depth. The classic oval shape is always popular and works beautifully for rings, pendants, or earrings where you want something that catches the eye. This pipe opal formation gives it extra translucency and brightness compared to typical crystal boulder opals. It would look fantastic in custom jewelry settings with sterling silver for everyday pieces, or gold for something more upscale.

This is completely natural solid opal with no treatment, keeping its ironstone backing for stability. Not a doublet or triplet, just genuine Queensland crystal boulder opal formed naturally in pipe deposits. The bright green fire against the purple body creates really nice contrast, and the concentrated color in the center makes it more visually striking than opals with scattered fire. The 4.7mm depth helps the colors really pop when light passes through.

As the official opal October birthstone, this stone carries meaning around hope and creativity. The vibrant green and purple combination gives it an energetic, eye catching presence that works well for statement jewelry or special gifts. For anyone looking for authentic Australian opal with bold color and good size, this crystal boulder delivers quality at a friendly price point.

This crystal boulder opal will arrive securely packaged in an Opal Galaxy luxury gift box, ready for professional jewelry setting or safe storage.
