This Lightning Ridge Black Opal is a standout Nobby gem, hand-cut to showcase its extraordinary natural beauty. Weighing 7.64 carats and measuring 13.1mm wide x 17.2mm high x 5.1mm thick, this stone presents a true N1 black body tone — the most sought-after in black opals for its depth, brilliance, and vivid colour play.

The colour pattern is spectacular, resembling a galaxy when viewed up close. Brilliant flashes of violet, blue, green, and red scatter across the dark background, giving it a cosmic, three-dimensional feel. The opal is clean, with a high polish that enhances its clarity and intensity under both natural light and indoor lighting.

This piece is an outstanding candidate for high-end jewellery, a centrepiece pendant, or an elite addition to any opal collection. Lightning Ridge Nobby opals of this quality are highly prized and rarely offered, making this a serious investment Australian black opal gemstone.
