Blue Agate – Slab and Tiles


The stone was given its name by Theophrastus, a Greek philosopher and naturalist, who discovered the stone along the shore line of the river Achates (Greek: Ἀχάτης) sometime between the 4th and 3rd centuries BC. Colorful agates and other chalcedonies were obtained over 3,000 years ago from the Achates River, now called Dirillo, in Sicily

Other forms of agate include Lake Superior agate, carnelian agate (exhibiting reddish hues), Botswana agate, blue lace agate, plume agates, moss agate, tube agate (with visible flow channels or pinhole-sized ‘tubes’), fortification agate (which exhibit contrasting concentric banding structure reminiscent of concentric defensive ditches and walls etc around ancient forts ), fire agate (which has internal flash or ‘fire’, the result of a layer of clear agate over a layer of hydro thermally-deposited hematite), Mexican crazy-lace agate, which often exhibits a brightly colored, complexly banded pattern (also called Rodeo Agate and Rosetta Stone depending on who owned the mine at the time).
