Mineral Family: Blue Chalcedony is a Silicate mineral. Silicate minerals form the largest family of minerals, including more than 25% of all known minerals and 40% of all common minerals. In addition to being a major part of the Earth’s crust, Silicate minerals have also been found on the moon and in meteorites. Silicates are minerals which contain the elements Silicon (a light gray shiny metal) and Oxygen (a colorless gas). Together, these two elements form a tetrahedron – a shape similar to a pyramid – with a Silicon atom in the center and Oxygen atoms at each of the four corners. These tetrahedra connect with other chemical structures, in six different ways, to form various minerals and rocks. There are six main groups of Silicate minerals, and these main groups are further subdivided into secondary subdivisions, such as Quartz and Feldspar. Quartz is a large mineral family in its own right, and has two main subdivisions, macrocrystalline (crystals that are large enough to be seen by the naked eye, for example, Amethyst) and microcrystalline (crystals so small they can only be seen through a microscope, for example, Agate). All microcrystalline Quartz falls under the subcategory of Chalcedony, which is then further subdivided. Some of the minerals in this category are called Chacledony, some are called Agates, with others have unique names like Carnelian or Onyx. There are no natural blue Agates, so any authentic microcrystalline Quartz would be called Blue Chalcedony.

Formation: Blue Chalcedony is created when liquid magma from a volcanic explosion cools down and transforms into igneous rock. During this cooling down period, silica acid bubbles shift from being a gas/liquid into a solid compound. The bubble becomes a hollow space in the igneous rock and the silica acid becomes Quartz crystals. Chalcedony is formed when thin sheets of Quartz are layered with other minerals, creating a wide variety of colors and patterns. Trace particles of various impurities, including Iron, Nickel, Copper and/or Titanium gives Blue Chalcedony its coloring.

Mining: Typically mined from primary deposits which still have their original relationship with the host rock.

Enhancements: All Blue Chalcedony may be considered fully natural, enhanced only by cutting, tumbling, and polishing. The specific shade of blue can often be used to identify the deposit. Light blue Chalcedony is often mined in the United States (California and Nevada) while the almost lavender-hued Chalcedony, sometimes called Holly Blue Agate, comes from Oregon. Bright true blue Chalcedony most commonly comes from Namibia.

History of Blue Chalcedony

Today, Chalcedony is a large mineral family that includes all of the Agates and Jaspers, as well as many other unique stones. However, in antiquity, the name Chalcedony referred to a specific translucent mineral whose color ranged from milky-white to pale blue. It was included in many early lapidaries, texts that describe gemstones and their powers. The bright Blue Chalcedonies found in southern Africa and the western United States, by contrast, were not documented until relatively recently.

The name Chalcedony is believed to come from the ancient seaport of Chacedon, which today is a district in modern Istanbul, Turkey.  he earliest reference to Chalcedony dates back to the Byzantine Era and states, “The stone Chalcedony is bored in iron: he who wears it conquers.”A poem written around the same time described the stone as one which, “shines with a faint paleness. It comes between the hyacinth and the beryl. Anyone who carry it will, it is said, be successful in lawsuits.”From the medieval period onward, lapidaries linked Chalcedony to the weather and stated that it could offer protection from storms, both natural ones and those found in the heat of battle.

Medical texts prescribed Chalcedony to strengthen the eyes and treat eye diseases, to increase lactation in new mothers, as well as a cure for depression. It was specifically suggested that Chalcedony be worn as a bead and strung on donkey’s hair for best results, regardless of what specific protection, healing or good luck, was desired from the stone!

Natural blue stones are relatively rare, and in the case of Blue Chalcedony each deposit has its own distinctive shade. As a result, many of the deposits have distinct names associated with them, such as Ellensburg Blue (found near Ellensburg, Washington USA), Holly Blue Agate (found near Holly, Oregon) and Mount Airy Blue Agate (found near Mount Airy, Nevada).

Healing Properties of Blue Chalcedony

Spiritual: Blue Chalcedony is a wonderful communication stone for prayer, channeling, and spiritual writing, helping us to both hear accurately and to communicate our own thoughts clearly. It provides centering and a reminder of who we truly are, from our highest spiritual vibration, through our emotional and mental bodies, and down to our basic animal self. Blue Chalcedony teaches us that all of these parts of us are good and worthy of attention and respect. Blue Chalcedony repairs the energy fields in the aura and along the meridians, sealing any holes caused by trauma or neglect. Blue Chalcedony is attuned to the Throat and Third Eye Chakras and linked to the astrological signs of Cancer, Sagittarius. It is connected to the element of Water and vibrates to the number 9.

Emotional: Blue Chalcedony has a calm, cool, and lighthearted energy that is very soothing to the emotional body. It enhances our self-awareness and encourages us to be more responsible, without becoming overly serious. Blue Chalcedony reduces the power of both anger and fear. It gently dissolves anxiety, particularly that which is related to public speaking, performing, or emotionally charged conversations. It helps us to carefully consider our words and their effect, while being optimistic that we will be clearly heard and understood. Blue Chalcedony is an excellent stone for working with our Inner Child, especially if that part of us has felt misunderstood or dismissed for far too long. It encourages us to be more friendly and open, and to enjoy the company of all beings; human, animal, plant, and mineral!

Mental: Blue Chalcedony improves memory and mental dexterity. It can be used to help us learn foreign languages, understand complex ideas, and be more diplomatic in our own speaking. Blue Chalcedony inspires creativity, particularly for writers, and calls in the muse for guidance when creating abstract works of art. It encourages us to be more open to new ideas, including ideas in highly-charged topics like politics, religion and sex. Blue Chalcedony helps us to truly listen and to be willing to integrate new information into our existing framework, or even to shift into an entirely new paradigm if necessary. Such mental shifts are done gently so that we are not emotionally or mentally overwhelmed.

Physical: Blue Chalcedony is used by metaphysical healers for healing anything related to the throat and respiratory tract. It is believed to be especially good for vocal strain, due to singing/shouting as well as damage caused by smoking. It is believed to reduce extreme weather sensitivity, as well as pressure in the eyes and ears. Blue Chalcedony is also said to encourage lactation in new mothers and reduce weight retention, making it an excellent postpartum crystal.

Always use wisdom when considering crystal therapies for healing.

Earth to Pocket

Earth to Pocket is the Moonrise Crystal business mission. It’s the promise that any stones purchased here will be consciously sourced and the journey of the stone, from the Earth and into your Pocket, will be as transparent as possible.

These Blue Chalcedonies were mined in Namibia and tumbled (polished) in South Africa.

I met the owner of the South African tumbling company at the 2014 Gem and Mineral show in Tucson, Arizona. This company only sells tumbled stones twice a year, once at the Tucson show and later at the Sainte Marie Aux Mines International Mineral and Gem Expo in Provence, France. They offer the largest selection of high quality tumbled stones in the industry and are one of my favorite suppliers.

It would be my pleasure to hand-select a beautiful Blue Chalcedony for you.

Your Stone

This price is for one stone. You can buy a single piece of Blue Chalcedony or several, depending on your individual needs. Each Blue Chalcedony measures approximately 1 inch at its longest length and has a unique shape with soft edges. Tumbled stones are natural products and variations are part of their beauty.

The stone I choose for you will be a gorgeous, vivid, translucent blue. If you buy multiple stones, I will choose stones that look and feel particularly good together. Stones will be cleansed and smudged with sage before being shipped to you.

With their beautiful color and clean energies, these Blue Chalcedonies are perfect for crystal healing. Add them to a medicine bag, place them on an altar, fashion them into jewelry or simply carry them in your pocket.

Safe Handling of Blue Chalcedony


Blue Chalcedony Stones should not be left in sunshine for extended periods of time, as they will gradually lose their color. It is always considered a “best practice” to keep your stones and crystals out of direct sunlight as much as possible.

Good To Know:

Blue Chalcedony Stones are physically durable stones. As long as they are rounded and without thin edges, they can be carried in a pocket or medicine bag, or worn as jewelry on an everyday basis, without significant danger of the stone chipping or breaking.

Blue Chalcedony can be physically cleansed with water or a dusting cloth.

Blue Chalcedony can be energetically cleansed using any method. They will appreciate being soaked in fresh water, set outside to absorb the moonlight, and/or being smudged with smoke or incense. Use your own intuition to determine the best method.

Tumbled and fully smooth Blue Chalcedony Stone can be safely used to make direct-infusion “Blue Chalcedony Stone Water” for drinking or bathing. Before making any direct-infusion elixir ALWAYS check the mineralogical properties of the stone to ensure it is not toxic. Only use fully tumbled stones or natural Quartz points in direct-infusion elixirs, never rough stones. When in doubt, make an indirect-infusion elixir instead.

Blue Chalcedony Stones can be left in sunshine for extended periods of time without losing their color. However, it is always considered a “best practice” to keep your stones and crystals out of direct sunlight as much as possible.
