An Introduction

Chalcedony is a nurturing stone that promotes love in all shapes and colors.

Scientifically, Chalcedony is not an independant mineral species; rather it belongs to the Quartz family. However, being such an old name in the trade world, generally, Chalcedony is considered as a separate entity by itself.

The stones come in an array of colors, forms, and patterns, and have been used since antiquity. Most often, only single colored and translucent forms of the stone are sold under the name ‘Chalcedony.’ Other types of Chalcedony are sold with their individual names like Agate, Jasper, or Carnelian. The stone is believed to absorb negativity and promote harmony in body, mind, and spirit.
