Spiritual Healing Properties

Blue Opal is a beautiful wisdom stone that increases our discernment and helps us to trust our inner-knowing.  It helps us to grow up and grow past the limitations that may have formerly held us back.  While many people prefer comforting lies, rather than face uncomfortable truths, Blue Opal helps us to realize that “Truth is Comforting.”  Blue Opal helps us to open our eyes and to see what is plainly before us.  Problems need to be called out and solved, not buried and wished away.  Blue Opal gives us courage and helps us pick a good path that will lead us to freedom and peace.  It is a wonderful stone for deep personal work, shadow work, and for transforming into our Highest Self.

Emotional Healing Properties

All Opals have a relaxed, sensual and confident vibration.  Blue Opal is particularly good for helping us to express our wants and needs, and to clearly hear what other people want and need from us.  It also encourages us to have better boundaries and discernment in our interactions with others.  It helps us to see who we can share our most intimate thoughts with, and who we should keep at a distance for social comfort and our own wellbeing.  If we lived through trauma, Blue Opal reminds us to not trauma-dump on people we’ve just met or to trauma-bond with people who we otherwise might not deeply connect with.  Blue Opal gently helps us to separate the trauma of the past, from our current and future life.  It is an excellent stone to take to therapy and is highly recommended for anyone who is starting to date again after getting out of a toxic relationship.  Blue Opal encourages us to be wise and to prioritize people who bring peace and honesty into our life.

Mental Healing Properties

Blue Opal encourages us to live deeply and fully in the present, and to guard our thoughts from trying to dwell in the past or future.  There is a big difference between pro-active thinking and aimless ruminating, and Blue Opal shows us where that line is so that we can stay on the right side of it.  Blue Opal is a wonderful stone for creative people, especially for collaborators.  It opens up our imagination and inspires us to try new things and work with new people.  It asks us to do our own part with excellence and joy, and to be patient and encouraging to others for their part.  Blue Opal is great for teambuilding and coalition building, it invites us to be problem-solvers, beauty-makers, and wisdom-keepers.

Physical Healing Properties

Blue Opal is recommended when our body is out of balance and we need to make some adjustments.  It helps us to clearly see where the problem lies and what needs to be done to fix it.  It helps us to keep our emotions in check and not moralize a situation.  Issues need to be addressed, and Blue Opal reminds us that adding a layer of guilt or shame does not add anything useful to the equation.  If a problem cannot be fixed, Blue Opal helps us to calmly accept what is and not yearn for what cannot be.  Blue Opal encourages us to speak the truth and make the necessary adjustments without any muss or fuss.  It is a beautiful talisman for metabolism and for fatigue.  It is also a great talisman for dealing with hair loss or other upsetting changes in our physical appearance.

Geology of Blue Opal

Where does Blue Opal come from?

Opals are found worldwide, but 90% of all Opals on the market are Australian in origin.  Blue Opals are quite rare.  They may be found in Australia, they are also found in Chile, Ethiopia, France, India, Mexico, and the United States (most famously in the Owyhee Mountains along the Idaho/Oregon border).

Mining and Treatments

Most Precious Opals are found in thin layers embedded in sandstone and are the primary focus for many mines. Some of the mines are small affairs, while others are huge operations that create vast tunnel systems through the sandstone. Precious Opals are found using UV lights. Common Opals, by contrast, are secondary stones found in a wide variety of mines and mining conditions.

Lab-created Precious Opals are available in the fine gemstone market. Common Opals, by contrast, are all fully natural, regardless of the shade of color, enhanced only by cutting and polishing.

Mineral Family

Blue Opal is a Silicate mineral. 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 Feldspars. Opal comes in two main varieties, precious and common. Precious Opals have a fiery play of colors sparking across their surface. Common Opals, by contrast, lack this fire and have an opaque, flat color.

Blue Opal’s energy works well with its family – other Silicate minerals.  Try it in combination with Amethyst, CitrineClear Quartz, PrasioliteRose Quartz, and Smoky Quartz.  It also blends perfectly with other types of Opal such as Green, Pink, Purple, White, and Yellow.

Blue Opal Formation and Crystal Associates

Common Opals are fairly widespread and can be found in most types of rocks, wherever silica-bearing waters are found. Opals are especially abundant near hot-springs and Opal often is part of the fossilization process for Petrified Wood as well as fossilized seashells and bones. Precious Opals, by contrast, are much more rare and can only be found enclosed within a rock, where over time the water is slowly removed from the silica gel, a process which can take thousands of years. The silica left behind settles down and, if it settles in the correct formation, it results in the iridescent color which plays across the gem’s surface.

Blue Opal’s energy works well with its “friends” – crystal associates formed in the same geological environment.  Try it in combination with Apophyllite, Cavansite, Picture Jasper, and Rainbow Obsidian.

History of Blue Opal

Opal is included in virtually every known lapidary, texts which describe gemstones and their powers. Most of the legends associated with Opals refer specifically to the Precious Opals that contain flashing  colors.  Opals with a solid stabile color are known as Common Opals. The name Opal most likely derives from the the Sanskrit upala, meaning “precious stone.” It has also been suggested that the name may also come from Ops, a Roman Earth Goddess associated with fertility and the harvest.

At one time, Opals commanded a higher price than any other gemstone, far higher than Diamonds or Rubies. Pliny the Elder (CE 23-79), a Roman author, naturalist, and philosopher described Opal in his lapidary, The Natural History of Precious Gemstones. He related that a generation before him, there had been an enormous Opal, as big as a hazelnut, which had set into a ring which was worth more than a villa. It was owned by a Roman Senator named Nonius. Marc Antony, the most powerful man in the Roman world at that time, demanded that the Senator give the gemstone to him so that he could it to his lover, Queen Cleopatra. Nonius refused and fled, leaving all his worldly possessions behind, taking only the Opal ring.

Today, the vast majority of Opals come from the outback of Australia. The “Opal Capital of the World” is the small desert town of Coober Pedy, in Southern Australia. Opals were discovered in the desolate Stuart Mountain range in 1915, by a 14-year-old boy named Willie Hutchinson. He and his father were searching for gold but instead found a mother-lode of pale white sparking gems.  An Opal Rush began, and hundreds of men seeking their fortune poured into the “Stuart Range Opal Field.” This name was deemed too boring, and was replaced with kupa piti, Aboriginal words that meant “the boy’s watering hole,” a nod to Willie Hutchinson. In a bizarre turn of events, Willie died in 1920 while swimming in a water hole. Kupa piti gradually become Coober Pedy, which local residents now claim means “white man in a hole.”

Australia occasionally produces Precious Blue Opals, typically these are White Opals that have a bright blue iridescence, usually the iridescence is mixed with hues such as green or yellow.   Precious Blue Opals also come from Ethiopia, once again they are White Opals with a rainbow glitter, in which the neon blue hues can be seen dancing with equally vibrant shades of green, pink, and yellow.

Common Blue Opals are found in small deposits in several countries.  The most famous deposit are the Owyhee Opals, a sky-blue variety found in the Owyhee mountains that border Idaho, Nevada, and Oregon.  The term “Owyhee” was originally used to specifically designate Opals minded in this area.  As often happens in the crystals industry, the name has been co-opted and is sometimes used for Blue Opals mined in completely different location, such as India.  The reason this happens is that wholesellers and retailers think they can get a better price or sell more stones if it has a fancy name, rather than a simple descriptive name like “Blue Opal”.  In order to be considered a true Owyhee Opal, the gem must be from the Owyhee mountains.

The name Owyhee is actually an older spelling of the word Hawai’i.  Between 1810-1813, parts of the Pacific Northwest were mapped by John Jacob Astor’s Pacific Fur Company.  The expeditions included Native Hawaiians.  This was because the Pacific Fur Company sent out two expeditions, one that traveled across the land and the other that traveled by sea.  Due to prevailing winds, ships that sailed around Cape Horn, the tip of South America, would land in Hawaii to take on fresh food and water, before re-crossing the Pacific back to North America.  When the Pacific Fur Company ship landed in Hawaii, they were given permission by King Kamehameha (c.1758-1819) to take forty Hawaiians with them.  The Hawaiian king had only very recently united the Hawaiian islands under his rule, and he was curious about the wider world.  As a result, more than a thousand Native Hawaiians visited or immigrated to the Pacific Northwest during the 19th century and they gave their name to the Owyhee Mountains, Owyhee River, and Owyhee Canyonlands.

There are numerous myths associated with Opal, some romantic and others gruesome.  For more information, please see the longer history article on White Opal.
