Know about Agate gemstone





Agate stone

Agate, pronounced as agit, was christened by a Greek philosopher and a naturalist Theophrastus way back in between 4th and 3rd centuries BC when he first spotted agate on the banks of the river Achates in southwestern Sicily. Agate is an impure crystalline form of quartz defined by distinctness of grain and brightness of color.

Agates have an interesting history attached to them; they tell the story of Earth’s evolution. Creation of agate has an intriguing connection to volcanic eruptions that have been responsible to a great extent in shaping the Earth. Most of the agates have been known to have formed during ancient volcanic activities. The empty spaces or cavities formed by lava gave opportunity to silica rich water to enter to spell magic. When the silica in the solution travelled out, it formed silica crystals filling empty spaces from outside inwards. This is how agates acquired their characteristic and Nature’s most creative bands and cloudy patterns.

A logical corollary is that no two agates look alike. So much so that two stones cut from one single rock are dissimilar. Though most agates are related to volcanic rocks, some have their genesis in metamorphic rocks as well.

There will hardly be a color agate is not found in. There are black, grey, brown, yellow, pink, green, blue agates used for making jewelry, mortars, pestles, burnishers polishers and for healing purposes.

Agates are fairly resistant to weathering and remain as nodules in soil or as gravel in riversides. Though they’re found throughout the world, Brazil and Uruguay top the list of agate producing countries. Scottish agates are enviously second to none in their color and texture; they were often called “Scottish Pebbles” during nineteenth century due to their ready availability on Scottish seashores.
