This Lightning Ridge free from gem carries medium brightness of 4/5 and the colour sits on top of a grey/light base.  It has a multi-colour spectrum and rare unique pattern, not seen often in opal. This will make stunning eye catching jewellery or be a great addition to your collection. These do not come up for sale often and are tightly held as investments and sought after by collectors of unique gemstomes. It weighs 10.5 carats and measures 19.9 x 14.8 x 4.95  mm. It is shown here in low natural light, at sunset. This gem shines brightest and looks the best in natural sunshine, but is hard to capture on camera, so no video is included here.
