Gemini Birthstone Guide: Lucky Crystals & Their Meanings

Are you a Gemini? If so, there are not only monthly birthstones but plenty of lucky Gemini gemstones for you to benefit from. 

Both astrology and gemstones go back thousands of years. Humans have looked down at the Earth’s crystals and up at the stars to seek inspiration or answers for centuries. 

This is especially true for Geminis, who thrive on obtaining knowledge, insights, and new perspectives that they can share with others. 

In this guide, we’ll break down the monthly Gemini birthstones along with some lucky zodiac stones for the sign, along with each of the crystal’s meanings and uses. 

But first, we need to establish what being a Gemini truly means. 

What Does Being A Gemini Mean?

You’re a Gemini if you were born from May 21 to June 20, the sunny and fresh start of summer. 

A few of the positive traits associated with Geminis include being outgoing, curious, and great at communication. This sign is the life of the party in the sense that they can talk to anyone and everyone, always wanting to broaden their perspective and keeping conversations lively with their quick wit. 

On the other hand, some negative traits associated with Geminis include being flighty, impulsive, and overly impressionable. These may tie into Gemini being an air sign, as air signs are intelligent and sociable but also prone to indecision and distraction. 

Gemini is also a mutable sign, meaning they fall between seasons — in this case, the transition from spring to summer. Mutable signs like Gemini are adaptable and don’t shy away from change. However, they can also be restless and inconsistent. 

Of course, it’s impossible to ignore Gemini’s symbol, the twins, and the reputation this carries for Geminis. Even non-astrology enthusiasts have probably heard the rumors of Geminis being two-faced or gossip hounds. This can be true, but the duality of the sign really allows Geminis to see more perspectives than most. 

The sign’s planetary ruler in both traditional and modern interpretations is Mercury. Mercury is the planet of communication, knowledge, and curiosity. The house associated with Gemini is the 3rd house, which similarly governs communication, information, and learning. 

With that foundation laid, let’s get into the monthly birthstones associated with Gemini birthdays. 

Monthly Birthstones for Gemini

Traditions relating to 12 birthstones for the 12 months of the year have roots in Biblical texts, though the modern tradition started around the 1500s. The modern list of monthly birthstones, however, was established in 1912, standardized by the National Association of Jewelers. It was then modified in 1952 by the Jewelry Industry Council of America. 

If you’re familiar with monthly birthstones, you may wonder: is Gemini birthstone emerald? If you’re a Gemini born in May, emerald is one of your birthstones, but it’s not the only one. 

Below, we’ll go over the monthly May birthstones and June birthstones, along with what each one means. 

May: Emerald

Emerald is the number-one May birthstone on both historical and modern lists. The precious gemstone is a variety of beryl, joining fellow beryl varieties like morganite and aquamarine. 

On the astrological side, emerald is a planetary star stone for Mercury, Gemini’s ruling planet. That means emeralds bring out the eloquent communication and intellectual curiosity that Geminis love. 

Some Ayurvedic astrologers recommend wearing emerald as a Gemini birthstone ring on the right pinky finger for maximum benefits. 

May: Agate

The second May birthstone is agate, which isn’t just one stone. Rather, agate describes virtually any translucent, color-banded chalcedony stone. Agate appears on historical May birthstone lists rather than modern ones. 

Agate as a Gemini birthstone reflects the diversity and adaptability of the sign. Additionally, agate is a throat chakra stone, the chakra of expression and truth. Having agate means you can prevent a throat chakra blockage, which results in difficulty speaking your truth and feeling secure in your self-expression. 

Now, what are the June Gemini birthstones? May has two birthstones, but June has three. 

June: Pearl

Pearl is distinct from other gems on this list in that it’s not a mineral. Instead, it’s an organic gemstone, meaning it’s formed by a living organism via biological processes. Because pearls are mineral-like, they’re classified as mineraloids. 

Besides being a timeless fashion accessory, pearls also have plenty of ancient legends surrounding them. These range from pearls originating as the tears of deities to coming about from rainbows touching Earth. 

Most know them in their traditional shiny white form, but pearls come in many shapes and colors, including pink, blue, black, and even the Gemini power color: yellow. As a Gemini birthstone, pearl helps the sign find balance and harmony that can often be lost in the twin duality. Just be sure to review proper pearl care to ensure these birthstones last. 

Including pearls, what are the three birthstones for Geminis born in June? 

June: Alexandrite

Unlike pearls, which have been known for centuries, alexandrite is a more modern discovery and addition to June birthstones. First found in Russia in 1831, alexandrite is a chrysoberyl variety known for its extreme rarity and dramatic color-change from emerald-green in daylight or fluorescent light to ruby-red in incandescent light. 

Being so modern, it’s unsurprising that alexandrite was only added as a June birthstone in 1952 when the Jewelry Industry Council of America updated the industry’s standardized list. (They also added tourmaline for October, citrine for November, and zircon to replace lapis lazuli for December). 

Obviously, alexandrite’s color-shifting ability matches Gemini’s duality. Expanding on that, though, alexandrite’s colors are also complementary, allowing it to encourage Geminis to use their dichotomous abilities for good. 

After all, what better gem for the chameleon sign than one nicknamed “Chameleon Stone,” right?

June: Moonstone

The last June birthstone is moonstone, a feldspar variety known for displaying an internal, moonlight-esque glow called adularescence. Moonstone has been a June birthstone since the modern standardized list of 1912, but its uses and lore go back centuries. 

Ancient legends surrounding moonstone tell of the stone being made of moonbeams, inducing psychic abilities, and even shifting with the moon’s phases. Today, moonstones are just as magical (though we know more about their scientific side). 

As a healing stone, moonstone benefits Gemini in bringing good luck, balancing emotions, and sparking your creative side. Plus, you can rock some moonstone Gemini birthstone jewelry in all shades including peach, yellow, green, and more.  

That covers monthly birthstones, but what about the lucky Gemini crystals? 

Zodiac Stones for Gemini

Unlike monthly birthstones, zodiac stones are far from standardized in any way. Different astrologers — and even different astrological traditions — may consider various different gems lucky or beneficial to a particular zodiac sign. 

So, which is the best stone for Gemini? It depends on what kind of benefits you’re looking for, as not every Gemini is the same. But to give you a start, we’ll list some of our top Gemini stones and crystals below. 

Chrysoprase

The first lucky Gemini stone on our list is chrysoprase. Chrysoprase is a chalcedony variety, like the May birthstone agate, often found in an apple-green color from nickel impurities. 

This gem is a planetary stone for Mercury, and it’s said to help Gemini personalities manage impulsiveness and make decisions confidently. 

Additionally, chrysoprase is believed to give you greater confidence, poise, and mental clarity, all of which are important to Geminis. 

Tiger’s Eye

Tiger’s eye is another beneficial Gemini stone, though it’s not a mineral. Rather, it’s a golden-yellow or red and brown or reddish-brown rock largely made up of chalcedony and moganite inclusions. 

The inclusions are shaped and oriented in a way that allows tiger’s eye to display simple chatoyancy. This is an optical phenomenon similar to the “cat’s eye” effect but with multiple rays of light (just not star-shaped like asterism). 

For Gemini, tiger’s eye can boost courage, confidence, and perseverance — traits that can be hard to come by for air signs like Gemini but are no doubt crucial to being their best selves. 

Watermelon Tourmaline

The next Gemini crystal is watermelon tourmaline, a variety of… well, tourmaline. This variety is unique in being bi-colored — typically green, pink, and white — and unsurprisingly resembling a watermelon. 

Beyond evoking the feeling of summer that many Geminis hold dear, watermelon tourmaline also benefits this sign by balancing their duality, dispelling self-doubt, and encouraging them to slow down to focus on gratitude. 

Amethyst

Wait, amethyst? Isn’t that a February birthstone? Yes, but it’s also a metaphysical Gemini birthstone. Amethyst is a purple quartz variety nicknamed the “Stone of Peace.” You can also find lighter-toned lavender options called Rose de France amethysts. 

Mental clarity and relaxation are important for a Gemini to be at their best, and amethysts can help. These crystals are said to bring inner peace, mental clarity, and spiritual awakening that can help you understand yourself and your place in the universe more clearly. 

Citrine

The last Gemini stone on our list is citrine. Citrine is a sister stone to amethyst, though it’s yellow to orange instead. However, many citrine gems available are actually heat-treated amethyst. 

For one, citrine has the favorite yellow hue of Geminis. Spiritually, citrine has many nicknames, including “Success Stone” and “Stone of Abundance.” These monikers come from beliefs that citrine helps you manifest prosperity and wealth. 

Besides financial help, citrine also represents joy, optimism, and achievement, reflecting the sunny disposition that attracts people to Geminis. If you’re a Gemini, citrine can help you stay confident around others, keeping bad vibes away and letting the good times keep rolling. 

Balance & Thrive with Gemini Birthstones!

Despite the misguided rumors about Geminis being two-faced gossips, folks born under this sign are actually witty, social butterflies that love to expand their perspective. Though the duality of the twins or tendency to keep adapting may leave Geminis feeling imbalanced, wearing any of the Gemini birthstones (for women or men) can help you find harmony, success, and self-discovery. 

Fellow Gemini author Joyce Carol Oates summed it up well: “I never change, I simply become more myself.”
