jasper

appearance

Jasper is an opaque rock of virtually any colour stemming from the mineral content of the original sediments or ash.
Patterns arise during the consolidation process forming flow and depositional patterns in the original silica-rich sediment or volcanic ash.

formation

Hydrothermal circulation is generally thought to be required in the formation of jasper.

Isaiah 17:1 is a prophecy foretelling the destruction of Damascus, the capital of Syria, predicting that it would be reduced to a ruinous heap. The phrase “burden of Damascus” signifies a heavy judgment against the city, symbolizing God’s sovereign power over nations. The prophecy reflects God’s judgment on Syria and Israel for their rejection of Him and their alliances with foreign powers. While the immediate fulfillment of this prophecy occurred during the Assyrian invasions, some also interpret it as a prediction of Damascus’ future desolation in the end times.

Wikipedia

Jasper (Wikipedia) Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases, is an opaque, impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron(III) inclusions. Jasper breaks with a smooth surface and is used for ornamentation or as a gemstone. It can be highly polished and is used for items such as vases, seals, and snuff boxes. The specific gravity of jasper is typically 2.5 to 2.9. Jaspillite is a banded-iron-formation rock that often has distinctive bands of jasper.
