Natural Black Opal Gemstones
Natural black opal gemstones are valued for their dark body color, which enhances vivid flashes of red, blue, and green play-of-color. These rare opals are among the most sought-after varieties in the world.
Loose Black Opals for Jewelry
Loose black opals are ideal for custom jewelry designs, allowing jewelers to showcase each stone’s unique color patterns. They are especially popular for rings, pendants, and statement pieces.
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 Opal Cuts and Shapes
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.

On the clarity options it goes "and better" so if youre looking for si specifically and you click si and better it still shows you basically everything. It just removes the opaques. Itd be nice if it was vs only, vss only, si only, etc

The citrine gems are beautiful. I appreciated that each stone was individually shown on the website so I could see exactly what I was getting. No mystery person selecting random stones for me. The documentation included with each gem was high quality as well. Great price and arrived as expected.
