RECOMMEND POINT
Cobalt spinel is a rare stone with an elegant shine!

Spinel comes in a wide variety of colors.
The most popular colors are red, pink, and blue.

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

In recent years, gahnite, a rare stone created by replacing the magnesium component with zinc, has become a hot topic, but there are actually several types of spinel blue.

The blue color of blue spinel is usually caused by iron being the main component and a small amount of cobalt, but in rare cases this condition may be reversed.

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

Spinel is treated as a rare stone with very little circulation, but it is one of the most delicate stones among cobalt spinels.

Spinel containing cobalt bands generally has many inclusions.

Although there are some small indentations left in order to ensure the size, it has a wonderful degree of perfection with almost no inclusions.
It is a very high quality stone.

Cobalt spinel is a rare and elegant stone.
Enjoy this beautiful stone that shines sharply.
