Natural Dark Opal
This 4.22ct dark opal from Lightning Ridge is a stunning example of natural beauty and expert craftsmanship. Its high dome shape elevates the vivid rainbow floral mosaic fire that blooms across the surface in brilliant red, green, blue, and purple tones. Every angle reveals new colors and new layers of pattern, making this opal truly captivating.
The rainbow floral mosaic pattern gives the gem an organic, painterly effect that feels soft and radiant while delivering high visual impact. The smooth dome amplifies the way light moves across the surface, creating a fluid fire that shifts and glows. This gem is ideal for a custom opal ring, a dramatic pendant, or a high-end necklace design.
This opal is untreated and completely natural with no doublets or triplets. It is ethically mined from the Lightning Ridge opal fields in Australia and hand polished to preserve the clarity and fire. Its clean surface and intense colors make it a collector-level gemstone ready for bespoke jewelry.
