Today we will introduce you to a rare gemstone.
It's called Cuplite.
Cuprite itself has a low hardness, and there are very few cut stones on the market.
It's a very dark reddish brown. There are also some reddish brown ones.
However, I also found the ones that are closer to black to be very attractive.
This is because it has a metallic luster like hematite or black diamond.
It shines brightly and changes color to red.
The main component is copper, hence the name Cuprite (Cuprite)
