Chương 802: Hidden Gemstones

Within these rocks, Li Du found a lustrous piece of gemstone.

The piece of gemstone was approximately the size of a newborn baby's fist, had a pale black base color, was translucent, and had a colorful top.

Generally, the gemstones were like painter's palettes that had been filled with a variety of colored pigments. The various colored pigments blended with each other and were arranged in a messy but interesting manner, giving the gemstones a strange and eccentric charm.

With just one glance, Li Du was able to figure out the identity of the gemstone.

Black opal!

Indeed, the gemstone was a black opal. Furthermore, the gemstone was a top grade specimen that had a black base color.

It was common knowledge that the term, "black opal" generally referred to opals that were black or grey, had play-of-color, and displayed vibrant colors within their dark-colored bodies.
