PRECIOUS OPAL, LIGHTNING RIDGE DARK CRYSTAL – 4.45 ct. Oval

This dark crystal opal oval is from Lightning Ridge, Australia, famed for its valuable black opals. It displays brilliant broad flashes of neon green, purple, lavender and blue highlighted against an N5 moody dark background. Lightning Ridge opal is renowned as being dependably stable; I cut this gem over a year ago. This great stone is suitable for fine jewelry with diamonds. Approx. 4.45 ct. and 10.9 x 13.5 x 4.9 mm. October birthstone. (Some care, N)
