What is Chalcedony?
Chalcedony is a microcrystalline variety of quartz that forms in various colors and patterns. It is known for its translucent and sometimes opaque appearance, with bands or veins of different colors running through it. These striking patterns create a captivating visual effect, making chalcedony one of the most sought-after gemstones on the market today.
Properties of Chalcedony
Appearance and Color
Chalcedony exhibits a wide range of colors, from light to dark shades. Some common color variations include:

In addition, chalcedony may also display banding patterns in various colors. These bands can vary from thin lines to thick, bold stripes, creating an eye-catching visual effect.
Hardness
Chalcedony has a hardness of 6.5 to 7 on the Mohs scale, making it relatively durable and suitable for everyday wear. However, care should be taken when handling or cleaning chalcedony jewelry, as it can still scratch or damage if exposed to abrasive substances.
Cleavage and Fracture

Chalcedony can display a range of clarity levels, from nearly transparent to opaque. The translucent variety is often used for cutting cabochons, which are smooth, domed gemstones that showcase the stone’s natural patterns and colors.
