Chalcedony

Chalcedony is a type of quartz that comes in various colours, including blue, white, grey, and yellow.

It has a waxy lustre and is often found in the form of nodules or geodes. The word "chalcedony" comes from the Greek city of Chalcedon, known for its high-quality gemstones. Historically, chalcedony has been prized for its beauty and is believed to have mystical powers.

The Ancient Romans used chalcedony as a protective talisman and incorporated it into their jewellery. It was also thought to bring harmony to the body, mind, and spirit. In ancient China, chalcedony was associated with water and used to decorate worth objects such as vases and snuff bottles. Today, chalcedony is still prevalent in jewellery and is believed to have calming properties. Like the ions of the ocean, it is said to dissipate negative energy and transform it into positive vibrations.
