Chalcedony Beads

In general, Chalcedony is a microcrystalline variety of quartz. In its purest form, chalcedony is a translucent white color. However, it often contains microscopic traces of other minerals that give it a variety of colors. For example, carnelian is a variety of chalcedony that has a reddish-orange color due to the presence of iron oxide. Most gemstones on the market called chalcedony are a white-blue coloration.

Chalcedony has been associated with health since at least the European Renaissance. Today, it is still said to have a positive effect on human health, specifically mental health and fighting depression.
