This is a natural mineral and rock.
Obsidian is a glassy mineral formed by volcanic activity.
This mineral is formed when lava cools and solidifies rapidly.
Obsidian is typically dark in color and can sometimes have an iridescent sheen.
Particularly beautiful obsidian is processed into gemstones or used as decorative items.
Obsidian has been used since ancient times as weapons and tools such as blades and arrowheads.
Obsidian can have a very sharp edge and is also hard, making it an important tool for people in the Stone Age and Bronze Age.
Obsidian was widely used, especially in the Maya and Aztec civilizations of Central America, and played an important role as craft and ritual objects in those cultures.
Obsidian is also produced in some parts of Japan.
Particularly famous are Rebun Island and Rishiri Island in Hokkaido, and Mt. Daisen in Tottori Prefecture.
In these areas, obsidian has been formed by volcanic activity and mined.
Obsidian from Rebun Island and Rishiri Island, in particular, has a beautiful luster and pattern, and is highly valued as crafts and jewelry.
The Mohs hardness of obsidian is about 5.5 to 6.
It is harder than ordinary glass, but it feels softer than its sharp appearance might suggest.
It is also relatively easy to polish and process into gemstones.
Obsidian is believed to have the following healing effects as a power stone.
As with quartz, obsidian is believed to harmonize energy and promote mental stability and physical health.
The dark color and luster of obsidian are sometimes interpreted as bringing inner harmony and stability.
However, these are not scientifically proven and are based on individual beliefs and experiences.
As it is a natural raw stone, it is irregular and the color is not uniform.
Furthermore, impurities may be mixed in.
The images are taken with bright light, but it may appear slightly dull in normal lighting.
This is a raw stone, not a gemstone.
Please understand these points before purchasing.
You might want to try processing it into a gemstone using a natural stone polishing machine.
