Denim gray blue Indian Sapphire cabochon. It has not only a universally suitable color (almost everyone wears jeans) but above all hardness!

The color is natural. It has a subtle star effect in the sun.

Sapphire is the stone of kings, and its blue variant is one of the most sought-after (and also the most expensive in the case of transparent versions) gemstones, it belongs to the stones of the third eye, i.e. to the sphere of decision-making and intuition. It is a very strong stone, like all corundums. (it's also very hard)
