What is this stone names ?

I'm sorry, I cannot see the stone you are referring to. Can you please provide more information or a description of the stone?

The stone in the image is called __Aventurine__.

Aventurine is a type of quartz that is characterized by its aventurescence, which is a shimmering effect caused by the presence of tiny inclusions of mica or other minerals. Aventurine can be found in a variety of colors, including green, blue, red, brown, and yellow. It is often used in jewelry and other decorative objects.

The name aventurine comes from the Italian word "avventura," which means "by chance." This is because aventurine was first discovered in the 17th century in Italy, when a glassmaker accidentally dropped some copper filings into a pot of molten glass. The resulting glass had a beautiful shimmering effect, and it was soon given the name aventurine.

Today, aventurine is still prized for its beauty and uniqueness. It is believed to have a number of metaphysical properties, including the ability to promote good luck, prosperity, and creativity.
