Chalcedony Stone Meanings

Brown rocky geode with banded blue and white Chalcedony center

Chalcedony is a name given to a form of microcrystalline Quartz. Microcrystalline, also known as cryptocrystalline is a type of crystal that is so small that it's not seen by tthe naked eye. Chalcedony usually has a milky or transclucent appearance and is an all encompassing term that can include varieties of Agate, Jasper, Bloodstone, Chrysoprase, Onyx, etc in its classification. However, to avoid confusion, in the gem trade, Chalcedony is usually referring to a milky white, gray or blue version of the stone. 

Chalcedony rates a 7 on the Mohs Scale of Hardness so it is a pretty tough stone like Quartz. Because of its durability and abundance, Chalcedony was used often as weapons and tools during man's early days. 

Types of Chalcedony

Agate - banded Chalcedony comes in many colors. 

Bloodstone - a green Chalcedony with red, yellow or white inclusions.

Blue Chalcedony - a milky blue or blue-gray tone stone.

Blue Lace Agate - blue and white banded variety of Agate Chalcedony. 

Carnelian - a reddish orange variety of Chalcedony, sometimes banded.

Chrysoprase - a translucent green Chalcedony getting its color from Nickel. 

Jasper - an opaque Chalcedony that comes in many different colors. 

Onyx - the black and white variety of banded Agate.

Petrified Wood - Chalcedony crystallizes wood to create Petrified Wood.

Pietersite - a Chalcedony with amphibole mineral inclusions that can make the stone look iridescent. 

Sard - a brown to brownish red variety of Chalcedony, often associated with Carnelian

Sardonyx - reddish brown or black and white banded Agate Chalcedony.

    Sheila's Personal Experience with Chalcedony

    For a long time, I was confused by the Chalcedony classification. As you just learned, the classification encompasses so many popular stones.  I didn't know what to call and what not to call Chalcedony! Now, I have learned that in the gem trade, we can easily narrow down Chalcedony crystals by focusing on the un-banded, translucent or milky variety of the stone that may not easily fit under the other sub-categories of Jasper, Pietersite, Agate, etc.

    That being said, I have mostly been using the frosty gray Chalcedony over the years. Its muted color is easy to wear with a variety of outfits and its soft energies are easy to mix with stronger stones like Rhodochrosite and Pyrite. 

    Lisa's Experience with Chalcedony

    Chalcedony is an interesting stone. I haven't had much experience with chalcedony. I used to think only the light blue Chalcedony existed. I then encountered Hungarian Chalcedony that is a slightly darker blue and with lots of red inclusions. This variation won my affection. I believe Madagascar produces this variety as well.

    I appreciate the stone because there are not very many natural pieces that align with the Throat Chakra. I hope to work with Chalcedony more. I found one or two nice pieces in spheres, I would like to grow this number and make it a steady stone for our sphere collection.

    Chalcedony Stones & Jewelry

    The most popular form of Chalcedony in our stone collections are the ones that line geodes. As you may know, geodes are big hollow rocks that are lined with surprising crystals within. Sometimes the geodes are lined with sparkling Amethyst crystals with a border of Chalcedony. Sometimes you will find the geode rock lined full of pure milky Chalcedony.

    As for Chalcedony jewelry, it is not as commonly found because the other varieties of the stone are so much more popular like Jasper, Agate and Bloodstone. However, we do have a beautiful Blue Chalcedony and a frosty gray and brown Chalcedony from time to time. As of this writing, we even have a faceted bracelet set of the translucent gray and the mysterious brown Chalcedony available!

    For the best quality Chalcedony in jewelry pieces, you will want to look for a consistent frosty color throughout the stone. Organic inclusions are natural and welcome! Fancy pieces of Chalcedony are cut into cabochons and carvings and give a radiant glow because of its lusterous color.
