Most casual gem lovers know aquamarine and emerald, but one lesser-known beryl stone is heliodor! Heliodor is a yellow beryl gemstone with a near-flawless appearance and excellent durability, perfect for any accessory!
Beryl stones have been beloved for centuries, appearing in Biblical references, employed in new inventions, and explored through many mystical uses. Today, the U.S. state of New Hampshire recognizes beryl as their official state mineral.
Heliodor is a noble beryl, a term for any colored beryl gemstones that aren’t aquamarine or emerald. As a noble stone, is heliodor expensive?
We’ll answer that question today, along with all your other queries about heliodor properties, healing uses, and more!
Heliodor is a semi-precious gemstone that comes in shades of yellow, greenish-yellow, and golden-yellow.
Astrologically, heliodor is a zodiac stone for Gemini and Leo, the sign ruled by the sun! Regardless of your sign, many astrologers suggest wearing a heliodor gemstone ring to bring mental clarity, good health, and prosperity.
Gemologically, citrine is less scratch-resistant and has a different chemical composition. Visually speaking, however, the easiest distinction is that citrine often has warmer, orange undertones while heliodor has green undertones.
A heliodor gemstone may go by other names such as yellow beryl, precious beryl, or golden beryl. But wait, is heliodor golden beryl? It depends on who you ask.
Some gemologists insist heliodor and golden beryl are different stones, with golden beryl covering warm, golden-yellow hues and heliodor covering greenish-yellow hues. There’s still debate, but we’ll classify heliodor and golden beryl as the same.
Color: Yellow, yellow-green, golden-yellow, brownish-yellow
Crystal structure: Hexagonal
Luster: Vitreous (glass-like)
Transparency: Transparent to opaque
Refractive index: 1.56-1.58
Fracture: Conchoidal to uneven
Pleochroism: Present, though somewhat weak, in brownish-yellow to lemon-yellow
Optical effects: Sometimes chatoyancy; Rarely asterism
Now that you know what heliodor means geologically, what is the heliodor spiritual meaning?
The name “heliodor” comes from the Greek helios for “sun” and doro for “gift,” altogether making “gift of the sun.” In fact, many ancients thought heliodors controlled the shift from day to night. Plus, ancient Romans tied the stone to the sun god, Helios.
In ancient astrology, heliodor was a gemstone of Jupiter, the planet of luck, prosperity, and opportunities. Therefore, many believed the stone could attract abundance.
What about heliodor’s parent stone? What is the spiritual meaning of beryl?
The Bible recognized beryl as one of the twelve gemstones on the High Priest’s Breastplate, as well as one of the ten foundation stones in Revelation. Moreover, priest Ezekiel described God’s throne having wheels that looked like “gleaming beryl” in his book.
Elsewhere in history, beryl gemstones held significance as mystical tools. In Scotland, they were called “stones of power,” while Celtic druids used shiny beryls for scrying, a form of clairvoyance. In fact, mystics created the first crystal balls out of beryl!
Heliodor specifically symbolizes generosity, hope, and power. Nicknamed the “Stone of Selfless Leadership,” many healers claim heliodor crystal can bring inspiration, empathy, and altruism to those in leadership roles.
Speaking of, what does heliodor do spiritually?
By virtue of their energy and creation, all crystals have the potential to be healing stones, and heliodor is no exception.
As a yellow gemstone, heliodor inherently corresponds to intellect, joy, and self-confidence, bringing greater concentration and accomplishment.
For specific goals, what is heliodor used for? Let’s explore each area of heliodor gemstone benefits.
Heliodor physical healing benefits may include resolving issues in the liver and spleen, along with other digestive issues like nausea or bladder dysfunction.
Some claim heliodor crystals can help your body better fight illness and resist the effects of pollutants or toxins. Others tout the stone’s ability to help women cope with the symptoms of menopause.
Heliodor is a fire gemstone, bringing your inner fire to the surface. It’s said to increase confidence, strength, and determination.
Some say heliodor can soothe worries, reduce fatigue, and ward off those who’d want to use you. Altogether, heliodor is a powerful companion for becoming your healthiest, most confident self.
What chakra is heliodor? Heliodor corresponds to the solar plexus chakra, the center of personal growth. When the solar plexus is blocked, you may feel detached or unsure of yourself. After using a heliodor gemstone to open the chakra again, you can feel hopeful and empowered in pursuit of your purpose.
If part of that pursuit involves crystals, all the better! But before you buy heliodor, it’s best to know what goes into its value.
If you’re not sure what the true value of a stone is, that’s where gemstone properties come in! Experts examine key traits in each gem to determine its objective value, so that you can feel confident in your purchase!
Heliodor value traits include color, clarity, carat weight, treatments, and cut. We’ll look at heliodor color first.
Beryl gemstones are allochromatic, meaning the stone’s pure form is colorless and any coloring comes from additional elements. In heliodor’s case, its color comes from the presence of ferric iron.
The amount of iron determines the specific hue heliodor falls into. If iron replaces some aluminum, you’ll get golden-yellow. Other iron concentrations lead to a green heliodor undertone.
Heliodor falls under Type I, meaning it’s almost always inclusion-free and any inclusions present are only visible under 10x magnification. Since natural heliodor stones rarely show flaws, the smallest internal inclusions or external cracks can significantly lower value.
You’ll see different types of inclusions in heliodor, like:
Long, hollow tubes
Silk inclusions (very small parallel threads) can create chatoyancy—the “cat’s eye” effect. If the silk fibers are dense and oriented correctly, you may also see asterism, a four- or five-star ray of light on the surface.
Unlike rarer beryls like morganite and emerald, heliodor and aquamarine come in a range of sizes. However, good quality large heliodor gems are not as common. Even still, larger heliodors reportedly have the best golden-yellow coloring.
Typical heliodor treatments are heating, irradiation, dyeing, and impregnation. Most heliodors are irradiated, and only some are heated. In fact, only a select few mines worldwide produce heliodor rough that can handle irradiation or heat treatment.
Often, heat treatments change greenish-yellow heliodor to blue-green aquamarine tones. Alternatively, pale aquamarine may undergo irradiation to turn into yellow heliodor. Dyeing can achieve similar results, while impregnation is used for filling cracks.
Heliodor lends to virtually any cut. In faceted cuts, mirror polishing can create a wonderful shimmer as light dances among the facets.
According to 19th-century English scholar Thomas Kelly Cheyne, “Some of the finest examples of ancient Greek and Roman gem-engraving are found executed in beryl.” What other heliodor history lies ahead?
Besides carvings, ancient Greeks used beryl for healing kidney stones and bladder disorders. Physicians would prescribe drinking beryl-soaked water. Even by 1300 AD, scholars suggested the same elixir to treat asthma.
However, as one of beryl’s key elements, beryllium, is carcinogenic, we don’t suggest trying this yourself!
Beryl was among the earliest gems used by ancient Egyptians for animal carvings. Inventive Italians in 1400 AD used beryl to create the first model of eyeglasses, as glass at the time wasn’t as clear.
Despite beryl’s historical uses, heliodor wasn’t officially discovered until 1912 in Namibia. German geologist Erich Kaiser wrote of the new stone, named “heliodor” by Lucas von Granach.
“Heliodor” actually began as a trade name for golden beryl from the original Rössing, Namibia locale, but has come to describe all yellow beryl.
In 1914, the German mining company that made the Namibian discovery had a heliodor-and-diamond jewelry set created for the German Emperor to gift the Empress. The royal association boosted heliodor’s popularity until WWI, when heliodor fell out of public recognition.
Today, the largest faceted heliodor gemstone is a 2,054-ct., rectangular step-cut heliodor displayed at the Smithsonian Institution.
Now that’s a big rock, and that was after faceting! What happens before the heliodor comes to jewelers, though? How does a raw heliodor gemstone form?
Heliodor, like most beryls, almost always forms in pegmatites. Within pegmatites, hydrothermal deposits create the perfect environment for heliodor to crystallize.
Hydrothermal gemstone formation involves water flowing underground and collecting dissolved minerals along the way. The solution eventually settles into cracks or crevices and crystallizes. The beryllium present in heliodor comes from cooling magma nearby.
Once formed, you can identify some heliodor rough by its prismatic crystals with etched faces, caused by its chemical composition changing from overpressure.
Once it’s ready to be mined, where is heliodor found?
Today, the best heliodor specimens come from Brazil, Ukraine, and Nigeria. In fact, Brazil’s mines produce about 90 percent of the world’s heliodor, while Ukrainian miners have uncovered some of the largest, highest-quality specimens.
Other prominent heliodor locales include:
USA (Connecticut, Maine, and New Hampshire)
Most buyers are more concerned with the end result, however, so let’s talk price. What is heliodor worth?
The highest-value heliodor gemstone for sale would have bright golden-yellow coloring, no defects, and no green or brown undertones.
Large, high-quality stones like this can cost $60-$120 per carat, while similar-quality heliodors in pale yellow-green or orange usually cost around $30-$50 per carat.
Compared to other beryls, heliodor is on the low end price-wise. Both color and carat weight can dramatically alter the price per carat.
The heliodor price per carat reduces significantly in tan-yellow or pale specimens. These are typically roughly $10 per carat when around 2 cts. Golden-yellow specimens from 0.5-2 cts range from $15-$30 per carat.
Outside of faceted options, 20-40 ct., golden-yellow, untreated specimens here at GRA usually go for $9-$15 per carat.
Heliodor’s excellent durability and typical lack of inclusions make caring for it easy. You can use mechanical cleaning systems on heliodors without inclusions, though we recommend consulting an expert for underlying weaknesses before going in with your ultrasonic on high-blast.
Of course, you can also use the classic method of cleaning your gem in a solution of mild soap and warm water, and gently clearing away dust or debris with a soft brush. Dry with a microfiber cloth, and your gem will be sparkling like new!
Whether you want to celebrate your zodiac sign, incorporate some sunshine into your crystal healing, or invite more happiness into your life, heliodor stones can do it all. Simply wearing a heliodor ring will brighten your day and infuse your spirit with power that stretches back centuries.
