An exceptionally slim polka dot agate stone mounted as a ladies pendant in fine sterling silver. As with many varieties of agate this carefully chosen cabochon gemstone is translucent and boasts a vitreous lustre. This term describes the way that light interacts with the surface of the stone. Rocks and minerals with a vitreous lustre have an appearance and texture that resembles glass.
The colour and markings in polka dot agate is generally quite subtle. It occurs mostly in shades of bluish white to yellow to brown and the most prominent characteristic is its distinctive spots which can be any combination of yellow, orange, red, brown or even black. This type of agate stone comes from Oregon in the USA and was first mined by the Native American Indians.
