Obsidian is a felsic glass. At depth, it will crystallize to form granite. On the other hand it turns into perlite on reacting with water. At high grade it recrystallizes to form felsic glass.
Obsidian is actually a naturally occurring volcanic rock. It has a glass-like appearance and is formed when lava from the volcano solidifies so quickly that it bypasses the crystallisation process.
Obsidian, is a glass gemstone which is created in the fiery depths of a volcano, they surface during an eruption.
Materials produced when a volcano erupts are called volcanic products or volcanic materials. These can include lava flows, ash, gases, and volcanic rocks such as pumice and obsidian.
It can be use for jewellery and stone age arrowheads, as the obsidian was much sharper when made into a specific shape. It can be sharpened to a very thin thickness. It is very shiny and is black. This is why Obsidian is common to be used in jewellery. Obsidian is igneous rock, which means that it was formed either inside (intrusive) or outside (extrusive) of the volcano. Igneous rocks are basically cooled lava, or magma.
Obsidian is not an artificial stone. Obsidian is a naturally formed gemstone. It is formed by the sudden cooling of magma after the eruption from the back mountain pass and the extremely low temperature around it. As one of the common gemstones in life, obsidian is usually made into various accessories to wear, such as obsidian pendants, obsidian bracelets and other accessories. But in addition, because of the extremely sharp nature of the fractured part of obsidian, obsidian is currently used to make surgical blades as well.

You could find obsidian near a volcano.
Obsidian is an extrusive felsic igneous rock.
Obsidian is actually a naturally occurring volcanic rock. It has a glass-like appearance and is formed when lava from the volcano solidifies so quickly that it bypasses the crystallisation process.
Obsidian is molten silica (read sand) which has cooled rapidly after a volcanic eruption into brittle glass and is the reason why it chips easily into blades. Iron and magnesium give obsidian its dark color.
You have to make stone tools and then go to the dark cave on island 2. The harvest obsidian option then appears as you pass by deposits. You can also get it in the Volcano Summit in the third island.
When a volcano erupts the lava usually reaches water and when they collide it turns into obsidian (I know because of minecraft).

Well, I found some in my backyard. If you go somewhere near a dormant volcano maybe you might find some.
