Why Buy Black Opal from GemSelect?

Australian Black Opal

Most fine black opals originate from Australia, particularly Lightning Ridge. Australian black opal is renowned for its strong color contrast, durability, and consistent quality.

Black Opal Play-of-Color

The defining feature of black opal is its intense play-of-color, created by light interacting with microscopic silica spheres. Darker body tones make these colors appear brighter and more dynamic.

Black opals are commonly cut as cabochons to maximize color display, though select stones may be faceted. Popular shapes include oval, freeform, and pear.

Investment-Grade Black Opals

High-quality black opals with strong brightness and rare color combinations are often purchased by collectors as long-term investments due to their limited supply.
