Multiple colours: Green with some yellow and blue. Natural, Solid Black Opal - NO Treatments. Opals require direct light to show the true colour, pattern and brilliance and are best viewed in direct sunlight (or alternatively halogen or incadescent light but not flourescent light).
The better the grade and brightness of the stone, the less light is required to show the colour and brilliance. Please ensure that you check your opal in good direct light, as poor light may not show the true colour. The item "Make an Offer!
