Onyx
Onyx is a type of Chalcedony that happens naturally with tiny banded parallel layers. The mineral was first reported in 77 A.D. by Gaius Plinius Secundus and also named after the Greek word "claw" or "fingernail" due to its comparable similarity. The name obtained its use because of the form and brightness of the bands Onyx shows when sliced.

The Lava Stone
Lava Stone is created out of the fiery heat underneath the earth from raw energy. Lava stone is just one of one of the most typical rock kinds discovered ashore as well as oceans. Currently, lava rock is estimated to cover 8% of the planet's whole surface. It's a fine-grained volcanic rock developed of generally pyroxene as well as plagioclase minerals.

In ancient times, people extract lava stones and also have actually taken advantage of lava stone meaning for hundreds of years. In ceremonies, lava rock was used generally for security and courage. Ceremonial artifacts, consisting of beads, masks, and vessels made from lava rock have actually been uncovered from archeological websites around the world-- some of them dating back to over 8 thousand years ago.
