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.

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.
