Agates are semi-precious gemstones that are a variegated form of chalcedony (pronounced kal-sed’-nee). Agates naturally develop when an empty pocket inside a host rock fills in molecule-by-molecule, layer-by-layer as these microcrystals self organize to form concentric bands or other patterns. The colors and arrangement of the microcrystals are influenced by changes in pressure, temperature, and mineral content that occur during the formation process. Unlike other gemstones, each agate is unique. Even slabs cut from the same specimen will vary in color and design. This spring, agates are the rockstars in the design world. Choose agate or geode accents for high style organic luxury, and then stand back to enjoy the beauty of nature.
