Chalcedony is a type of quartz that comes in a variety of colors. It is often used in jewelry and other decorative items because of its unique appearance. Chalcedony can be found in many places worldwide, including the United States, Brazil, and Africa. However, various impurities cause the different colors of chalcedony in the stone. This blog post will explore the different varieties of chalcedony and their associated properties.
What is chalcedony?
Chalcedony (the name chalcedony comes from the Latin chalcedonius) is a type of quartz in various colors. It is often used in jewelry and other decorative items because of its unique appearance. Chalcedony can be found worldwide, including the United States, Brazil, and Africa. Various impurities cause the different colors of chalcedony in the stone.
Clear chalcedony
Clear chalcedony is a type of quartz found in various colors, including white, gray, yellow, and light purple. The most common form of clear chalcedony is the kind that is translucent or transparent.
Chalcedony is usually found in cryptocrystalline form, meaning it appears cloudy or opaque because the crystals are too small to be seen with the naked eye. When cut and polished, however, it can be pretty beautiful.
The different colors of chalcedony and their properties
Various impurities cause the different colors of chalcedony in the stone. Some of them are:
Gem Silica
Gem silica is a variety of chalcedony, a form of quartz. It’s a greenish-blue color and is considered to be quite rare and valuable. The term “gem silica” typically refers to the most prized specimens of this material, characterized by their intense blue hue and often have chatoyancy or a cat’s eye effect.
Agate
Agate is a variety of chalcedony, a cryptocrystalline form of quartz. It is deposited in cavities or along fracture lines in volcanic rocks. Agates are found worldwide and typically have a banded appearance because of the different minerals that make up the bands.
The colors of agate range from white to almost every color except blue. The most common agates are banded in shades of red and brown, but agates can also be banded in shades of black, green, yellow, blue, and violet. Some agates also have an “agate-line” or “eye” running through them. This thin line can be light or dark and is caused by a change in the direction of the banding.
Carnelian
Carnelian is a variety of chalcedony, a cryptocrystalline form of quartz. It gets its name from its deep red color, which is caused by iron oxide impurities in the stone. Carnelian is found worldwide, but the best quality material comes from India.
Carnelian is often used in jewelry and other decorative items because of its unique color. It is also believed to have metaphysical properties, such as promoting creativity, courage, and motivation.
Chrysoprase
Chrysoprase is a variety of chalcedony, a cryptocrystalline form of quartz. It gets its name from its green color, which is caused by nickel impurities in the stone. Chrysoprase is found worldwide, but the best quality material comes from Australia.
Chrysoprase is often used in jewelry and other decorative items because of its unique color. It is also believed to have metaphysical properties, such as promoting love, joy, and abundance.
Heliotrope
Heliotrope, also known as bloodstone, is a variety of chalcedony, a cryptocrystalline form of quartz. It gets its name from its deep red color, which is caused by iron oxide impurities in the stone. Heliotrope is found worldwide, but the best quality material comes from India.
Heliotrope is often used in jewelry and other decorative items because of its unique color. It is also believed to have metaphysical properties, such as promoting courage and strength.
Onyx
Onyx is a variety of chalcedony, a cryptocrystalline form of quartz. It gets its name from its black color, which is caused by carbon impurities in the stone. Onyx is found worldwide, but the best quality material comes from Brazil.
Onyx is often used in jewelry and other decorative items because of its unique color. It is also believed to have metaphysical properties, such as promoting grounding and protection.
Sardonyx
Sardonyx is a variety of chalcedony, a cryptocrystalline form of quartz. It gets its name from its deep red color, which is caused by iron oxide impurities in the stone. Sardonyx is found worldwide, but the best quality material comes from India.
Sardonyx is often used in jewelry and other decorative items because of its unique color. It is also believed to have metaphysical properties, such as promoting courage and strength.
Jasper
Jasper is a variety of chalcedony, a cryptocrystalline form of quartz. It gets its name from its deep red color, which is caused by iron oxide impurities in the stone. Jasper is found all over the world, including Australia, Brazil, Canada, Egypt, India, Indonesia, Madagascar, Mexico, Russia, and Venezuela.
How to care
Here are some advises:
- Chalcedony is a relatively soft stone that should be protected from scratches and abrasions.
- It is also a porous stone, so it should be sealed to prevent staining.
- To clean the chalcedony, use warm water and mild soap. Avoid harsh chemicals or cleaners as they can damage the stone’s surface. Chalcedony can also be cleaned with a soft toothbrush.
- When storing chalcedony, wrap it in a soft cloth to prevent it from scratching other jewelry pieces.
Uses of chalcedony
Chalcedony is used in a variety of ways in the modern world. It is popular in jewelry and other decorative items because of its unique color and appearance. It is also used in industry for its hardness and resistance to heat.
The use of very pure quartz crystals in oscillators and other electromechanical devices, such as watches, radios, and computers, is also well known. Chalcedony is used in these devices because of its piezoelectric properties, which can generate an electric field when compressed or distorted.
FAQ
What is chalcedony good for?
Chalcedony is said to promote harmony, compassion, and stability. It is also thought to be a protective stone that can ward off negative energy.
What color is chalcedony?

What is the difference between chalcedony and agate?
Agate is a variety of chalcedony, a cryptocrystalline form of quartz. The difference between agate and chalcedony is that agate has bands or streaks of color, while chalcedony is usually a single color.
How do you clean chalcedony?
To clean the chalcedony, use warm water and mild soap. Avoid harsh chemicals or cleaners as they can damage the stone's surface. Chalcedony can also be cleaned with a soft toothbrush.
Is chalcedony expensive?
Chalcedony is not especially expensive and is found in various colors and price ranges. Some varieties of chalcedony are rare and more expensive than others. For example, agate and carnelian are both forms of chalcedony, but carnelian is typically less expensive because it is more common. On the other hand, bloodstone and jasper are both types of chalcedony that can be pretty rare and expensive.
How is chalcedony formed?
Chalcedony is formed when the silicon in the quartz mixes with other elements, such as aluminum or iron. This creates a variety of colors and patterns in the chalcedony.
How to identify chalcedony?
The best way to identify chalcedony is to look for its trademark banding patterns. These bands are caused by the different minerals that make up chalcedony. So if you see a banded or striped stone with a slightly waxy appearance, it's probably chalcedony.
