Blue Agate Banded Tumbled Stone 20-30mm

Agate is a very fine grained form of Quartz. It grows within volcanic lava bubbles known as geodes. Diamond saws are used to slice the Agate it is then ground to remove any imperfections then polished and dyed to enhance and display the beautiful natural banding within.

The Agate stones that are found today come from deposits around the world in places like America, Argentina, Australia, Botswana, Brazil, India, Mexico, Myanmar, and Uruguay. With regular colour layers and bright colours, this variety is one of the most popular. These stones are found all around the world, but Brazil is one of the most productive sources. Many of the richly coloured, banded agates you see for sale are dyed.

These stones contain mossy inclusions of mineral oxides that may be any color. Stones that present plant-like patterns are called moss agates. Those with feather-like patterns are called plume agates. Those with tree-like, branching patterns are called dendritic agates.

Please Note: Natural gemstone or semi-precious stone comes from mineral. Due to the naturality, the stones may have a tiny flaw. Meanwhile, cutting or polishing also makes every piece of gemstone vary in colour and size. The image may look different (colour) due to many monitor or device resolutions.
