What is Iris Agate?

Iris agate is a finely banded, translucent variety of agate (a subtype of chalcedony) that separates transmitted light into spectral colors. When illuminated, it produces dazzling iridescent bands of all the rainbow colors. 

Hence, the name: Iris Agate! In Greek, iris translates to “rainbow” or “rainbow-like appearance.” In Greek mythology, Iris is also a messenger of the gods and the personification of the rainbow. 

Other monikers for the stone include Rainbow Agate or Iridescent Agate. 

Agate is considered a supportive zodiac stone for the Gemini. It’s believed to help these individuals maintain inner peace and focus.

Curious about how this colorful gem was discovered? Let’s talk history! 

Iris Agate Meaning & History

We know how iris agate got its name, but who found it?

Iris agate was officially discovered in 1933 by Fred S. Young, then publisher of the Oregon Mineralogist. He wrote about finding iris agate in Oregon. Since then, several other localities have been discovered. 

The first recorded mention of iris agate dates back to the 4th and 3rd centuries BCE. Theophrastus, a Greek philosopher and naturalist, mentions the mineral in his book, De Lapidibus (Latin for On Stones). 

Theophrastus is credited with naming agate after discovering the mineral along the shoreline of the Achates River of Ancient Greece (present-day Fiume Dirillo in Sicily).

Today, iris agate continues to be a popular and favorite stone for modern-day lapidaries, gem collectors, and crystal healers. 

Speaking of, let’s explore iris agate’s metaphysical characteristics! 

Iris Agate Healing Properties

Most gems are potent healing stones that can support your mind, body, and soul. 

In general, agate is considered stabilizing and helpful in reharmonizing the body. Iris agate is considered incredibly transformative, often called a “wish-granting crystal.” Its vivid colors and energy can lift your spirits, ease your physical body, and calm your mind in many ways. 

Physical Healing

Physically, what does iris agate do? It’s purported to unravel tension within the body. 

Iris agate also holds common agate’s powers; similarly, it can alleviate problems associated with your eyes, stomach, and uterus. 

Additionally, the crystal is used to cleanse the lymphatic system and pancreas, help strengthen blood vessels, and soothe skin-related disorders.

Emotional Healing

Regarding emotional healing, iris agate’s tension-relieving energies can help ease stress. It also shifts your perspective to a more positive outlook, allowing you to avoid a narrow viewpoint when handling stressful situations. 

If chilling out is on your list of wishes, grab some iris agate and consider it granted. 

Spiritual Healing

Into manifestation? Iris agate’s spiritual meaning of granting wishes makes this a powerful stone for manifesting. Simply focus on what you desire most, and iris agate can turn it into a fulfilled reality. 

Iris agate also acts as a universal chakra stone, aiding the balance of all seven chakras (or energy points) along your body. By doing so, it clears the way for harmony and energetic balance.

Shifting gears, how is iris agate graded?

Iris Agate Gemstone Properties

Most iris agate for sale is graded on color, cut, and carat weight. However, iris agate’s distinctive hues are most influential on its value — followed by its cut and size. 

Let’s see how each property stacks up. 

Color

Since color is arguably the most significant factor in valuing iris agate specimens, the most unique and iridescent ones tend to fetch the highest prices. 

Iris agate is most known for its eye-catching color patterns and banding. Under light (artificial or natural), it unveils a striking rainbow fire. Most photos simply don’t do this phenomenon justice. 

The mineral’s iridescence results from optical inhomogeneities (imperfections) and transparent impurities embedded inside.

Cut

It’s truly an art form to cut and polish iris agate for emphasizing its iridescence. Collectors and gem enthusiasts invest large amounts in custom cuts and rare varieties. 

Rough iris agate is often cut into slices to display its distinct color banding and pattern variations when held up to a light. It’s not as easy as it sounds, though! First, they must be sliced so that the exposed surface is perpendicular to the agate’s banding. The thinner the slice, the stronger the spectral colors. 

Afterward, the agate’s surface is typically polished, allowing easy light entry without the scattering caused by an unpolished surface.

Similarly, iris agate cabochons, ornamental carvings, and beads are also popular choices. Faceted cuts and intricate sculptures are rarer but do exist.

Carat Weight & Size

Agates are usually nodular, but masses can be several pounds and many inches in diameter.

Retailers tend to market iris agate in carat weight or grams. However, you may find some sellers that categorize them by length and width rather than mass. 

Next, let’s take a peek at how iris agate comes to be and where it comes from! 

Iris Agate Origin & Sources

Is rainbow iris agate natural? Yes! Its magical transformation from an ordinary agate geode to a polychromatic charmer adds to iris agate’s allure. 

So, how does it happen?

Most agate forms via volcanic activity. Air or gas bubbles within cooling magma gradually fill with silica-rich solutions. Eventually, these solutions solidify, forming agates in the shape of “thundereggs” (nodules). Sometimes, they grow inside cracks or layers, creating “vein” or "seam” agates.

Every agate is unique, but all are banded with different patterns and color variations. These variations usually result from impurities present during formation. 

Inclusions occur when iron oxide, manganese oxide, or other oxides are present during its formation. These oxides, which are pretty standard, grow and are supported in the agate when it’s in a liquid or gelatinous state.

However, iris agates aren’t a result of inclusions but rather a phenomenon of banding. Their dazzling rainbow effect results from tightly packed, thin layers and banding that can occur in colorless or pale chalcedony.

On that note, where do you find iris agate?

Rather skip the mining and shop instead? No worries — let’s talk pricing so you can prep your budget! 

Iris Agate Price & Value

Agates in general are typically quite modestly priced. Their value is more a reflection of labor and artistry rather than grading. Larger pieces with particularly unique color or pattern variations tend to fetch the highest prices. 

Mainly, iris agate is sold in its natural state sliced into thin slabs that allow illumination to shine through and highlight its rainbow-like color variations. Rough slices of iris agate generally go for about $7.35 to $11.50 per gram.

Faceted cuts are rare, but they do exist and vary in price. More commonly, iris agate is cut and polished into cabochons costing around $1.65 to $2.80 per carat. Higher quality and rarer specimens are pricier — for instance, $8.20 per carat. 

Custom cuts and iris agate carvings garner even higher prices, with some mounted sculptures going for as high as $3000.

Even though it’s relatively durable, iris agate jewelry can be harder to find. This is because the best way to highlight iris agate’s iridescence is by illuminating thin slices of it with light from behind. As a result, iris agate rings aren’t as popular. The same goes for iris agate bracelets. 

Instead, you’re more likely to find iris agate in dangling earrings or pendants for necklaces that make it possible for light to shine through one side. Prices generally range between $22 and $62. However, some pieces can cost as low as $12 or as high as $279.

Securing your iris agate is just the first step. Mastering how to care for your gemstones will ensure you get to enjoy their beauty and positive vibrations for years to come!

Iris Agate Care and Maintenance

When it comes to caring for your iris agate, simplicity works best. 

Use warm, soapy water and a soft-bristled brush to clean your gems. Avoid ultrasonic, heat, or steam cleaners as these could damage your stones.

For safekeeping, store your iris agate in a compact, fabric-lined box or a soft pouch to keep it from getting scratched or damaged.

Consider opting for iris agate jewelry that uses protective settings to preserve your crystal’s lifetime. Don’t forget to remove your iris agate jewelry before partaking in any rigorous activity like exercising or washing dishes.
