Black Opal 3.92 CT



RECOMMEND POINT
Neon play of colors spreads throughout the crystal
Rare black opal from Lightning Ridge, Australia!

This is a beautiful, high-quality black pearl from Lightning Ridge, Australia, with neon rainbow play of color that spreads throughout the entire crystal.

The beauty of the vivid iridescence of red, orange, green, yellow, and blue emerges in three dimensions.

The play of neon colors is particularly captivating, creating a truly vibrant color scheme.





Please pay particular attention to the vibrant red play of colors that appears as if burning when you shake it.

The contrast with the iridescent play of colors that spreads throughout the crystal is exquisite and makes a truly stunning impression.



Black opals are especially highly valued among opals that display mysterious play of color.

Currently, it is extremely difficult to obtain high quality black opals, and not only are prices soaring, but it is becoming increasingly rare to come across black opals that everyone finds beautiful.




The cabochon shape is plump and voluminous, allowing you to see a wonderful play of color from every angle.

And it's nearly 4 carats, so the size is plenty.

While most gem-quality opals have a single color or play of two colors, it is very rare to find a black opal that displays such vivid iridescent play of colors.

We highly recommend this to anyone looking for high quality black opal.
