Cobalt spinel 0.43CT

RECOMMENDED POINTS
This is a rare cobalt spinel stone that emits an elegant shine!

Spinel has a wide range of colors.
The most popular are red, pink and blue.

This stone is a cobalt spinel, which is extremely rare among blue spinels.

In recent years, the rare stone gahnite, which is created when magnesium is replaced with zinc, has been attracting attention, but there are actually several different types of blue spinel that can be attributed to it.

The blue color of blue spinel is usually caused by iron as the main component, with a small amount of cobalt, but in rare cases these conditions can be reversed.

Blue spinel with low iron content and high cobalt content is called cobalt spinel.

Spinel is extremely rare and is considered a rare stone, but it is one of the cobalt spinels with excellent luster.

Spinel containing cobalt bands generally has many inclusions.

To ensure the size, some small depressions have been left, but the stone is almost completely inclusive, resulting in an excellent finish.
It's a very high quality stone.

Cobalt spinel is a rare and elegant stone.
Enjoy this beautiful stone that shines with a sharp sparkle.
