Agate - An Ancient Gemstone with Diverse Beauty

When you think of stones, its often easiest to put them in separate buckets, but the amount of overlap between gemstones is sometimes remarkable. Take agate, for example, it is chalcedony which in turn is a member of the quartz family. It differentiates itself from chalcedony with its moss like inclusions, patterns, and translucency.

Since ancient times, agate’s beauty has been recognized as it has been incorporated into jewelry – it takes its name from the Achates River in Sicily where it was first reported. It is justly famous for its multicolored banded formation. Indeed, it is one of the oldest gemstones to be incorporated into jewelry. Agate comes in a wide variety of colors from black, green, blue, red, white, yellow, pink, purple, grey, brown, and orange.

Agates score high on the upper end of the hardness category (7 on a scale of 1 to 10) as they are formed within volcanic and metamorphic rocks.


Clean agates with warm, soapy water. Avoid contact with other gemstones because while agate is hard, it can still be scratched if it encounters an even harder gemstone. It is also best to avoid household cleaning products and chemicals.
