Agate Necklace

Agate is a microcrystalline form of quartz that can be found in many different colors. Agates are often named after the location of origin or their physical characteristics. Agates were first discovered in the river named Sicily in the early 3000 BC. Ancient Romans believed that the stone has divine powers that provide protection against any negative energy. Also known for its healing powers, agate was used for ointments and lotions. Many suggest wearing agate necklaces around the neck or keep them around at least 3 feet around you for their healing power to work.

This is one of the reasons why Agate necklaces are very popular. The agate stone also comes in different patterns and intriguing structures which makes for more amazing designs than any other gemstone. One of the rarest gemstones is ‘The Ellensburg Blue’ which is also a form of agate. Like the stone, the necklaces made from these particular stones are rare and very hard to find since they are composed of layers of blue chalcedony.
