About Black Australian Opal
- Origin: True black opals are found almost exclusively in Lightning Ridge, New South Wales, Australia, which is the source of virtually all investment-grade material.
- Appearance: The term "black opal" refers to the gem's dark body tone (ranging from dark grey to jet black) which makes its internal flashes of color appear more intense and luminous. It is not a completely black stone.
- Composition: The dark background is due to trace elements of carbon and iron oxide present during formation.
- Value Factors: Unlike diamonds, opal valuation has no fixed scale. Factors determining value include the body tone, brightness (vibrancy of color), pattern, and the rarity of the colors present, with red being the most valuable hue.
