Classified as the third sign of the zodiac, Gemini has two main birthstones that are connected to it: pearl and agate. Along with these, there’s a list of complementary birthstones for Gemini: moonstone, chrysoprase, alexandrite, citrine, sapphire, and tiger’s eye. Tiger’s Eye is also the planetary stone for the Gemini zodiac.

So who is considered a Gemini? Those born under a Gemini sun have birthdays between May 21 and June 20. The symbol for Gemini is “the twins,” a fitting name for the social butterfly of the zodiac. Gemini is an air sign alongside Aquarius and Libra.

The Gemini twins are represented by the twins Castor and Pollux. Known together as the Dioscuri, these twins are representative of the dual-natured personality. Geminis in general tend to exhibit two seemingly separate personalities. At one moment they may seem happy and good-natured and at a split second later, can seem cold and withdrawn.

Gemini sun signs are also known as the social butterflies of the zodiac. It’s rare to find a Gemini who prefers to be alone as this sign prefers to be around others. They’re extremely curious beings and like to know every detail about the lives of their friends, family, and even total strangers.

They’re abundantly curious about the world around them and have a need to know every minute detail. This tends to be a negative though because the Gemini can never feel satisfied with the information they learn. They constantly need more.

The Gemini is always inspiring and never boring. Because of their natural curiosity for the world around them, they’re extremely versatile from constantly trying new things. Geminis make great artists, writers, and journalists for these very reasons.

While pearl and agate are the top dogs when it comes to Gemini, there are several other connected gemstones worth noting.

While gemstones come from the Earth, the pearl is unique as it forms in the sea with the help of clams and mollusks. When a foreign body makes its way inside of the mollusk/clam, they begin a survival process to try and expel it from their bodies. 

The process involves the animal hardening the substance and adding more layers to the object until they form concentric circles. Those circles eventually form what we know as the pearl. 

The Pearl is considered the main birthstone for the Gemini zodiac sign. They’re polished and pretty and come with a number of both physical and metaphysical healing properties. Aside from being a good laxative, pearls are good immune system boosters and they encourage internal organ health too. 

It’s also good for soothing anxiety and preventing mood swings. If used for metaphysical reasons, pearl works best for channeling wisdom, purity, abundance, and intuition among other things. 

Agate is an ornamental stone made of a mixture of chalcedony and quartz. This gemstone is considered one of the oldest stones of the Earth as it dates back billions of years. Agate has been used in different cultures and civilizations for thousands of years. 

Ancient Mesopotamians believed the agate signified strength and the ancient Chinese would wear agate in necklaces to purify their minds and energize their chi. It was even tied to the horns of oxen in medieval times to promote a good harvest. 

The vibrational frequency of agate is low and gentle so it’s perfect for anyone who feels like they need to slow their life down. It also has stress relieving properties and helps you breathe deeper for relaxation. 

Agate also helps promote concentration and mental function which makes it a great crystal to have with you at school or work.

Citrine gets its name from the French word for lemon, ‘citron.’ Its yellow hue fosters positivity and encourages optimism in life. This is a variety of quartz crystal with deposits of iron inside of it. For centuries, people across many cultures have believed that citrine gets its healing powers directly from the sun. 

In ancient times, many people believed citrine could calm tempers, soothe anger, and manifest desires. Unlike other crystals and gemstones, citrine doesn’t actually need to be cleansed ever. This is because it absorbs, changes, and gets rid of any negative energy around it. 

Generally, people use citrine to manifest financial prosperity. When working with the chakras, citrine is great for waking up your solar plexus and encouraging you to channel confidence and willpower. 

Moonstone can be found virtually anywhere on Earth and is known for its iridescent blue-to-white color. This ethereal color is where moonstone gets its name as it doesn’t look like it’s from this Earth. 

While it’s easily breakable, moonstone is a popular choice in jewelry. Moonstone is a symbol for abundance, fertility, love, and renewal, and it has also been used across many cultures for centuries.

Those who use moonstone in their daily life use it to promote purification, self-development, spiritualization, and energization. This stone supports inner strength, restores balance, promotes fertility and new beginnings, and removes feelings of stress and selfishness.

In the Hindu faith, moonstone is said to have originated from moonbeams. Other cultures and religions have used moonstone in their prayers, rituals, and daily life for centuries. 

This stone is named after Prince Alexander II from Russia because it was found by miners in the Ural mountains during that time. Miners were said to be working one day collecting emeralds. When they were brought back to the camp, the miners found the gems shone red in the firelight. When they woke in the morning, the stones were green again. 

Alexandrite is a variety of chrysoberyl and it contains titanium, iron, and chromium. These elements are what gives the gemstone its signature green color. Alexandrite is considered a balancing stone and is great for manifestation and strengthening intuition, creativity, and imagination. 

Many people use alexandrite when working with their crown chakra as it grants you healing energy for the universe. 

Along with being a birthstone under Gemini, Tiger’s Eye is the planetary birthstone for the Gemini zodiac. It’s considered a stone of protection and helps focus the mind, mental clarity, and problem resolution. 

Tiger’s Eye gets its healing properties from the sun and the earth. It’s commonly used when working with the solar plexus chakra and has great grounding properties. The tiger’s eye will help clear chakra imbalances and encourage self-trust and self-sufficiency. 

In ancient times, this stone was worn during battle as it was thought to bring strength and protection. Much of these beliefs came from the fact that it has a very “eye-like” appearance. The eye represents all knowing power and the tiger's eye was thought to have the ability to ward off the evil eye. In ancient China, people wore it to bring good fortune. In Eastern myth, tigers represented courage, integrity, and power. 

Chrysoprase is a colored variety of chalcedony and is one of the oldest semi-precious gems used in healing. Known as the stone of Venus, chrysoprase was used by ancient Greeks, Romans, and Egyptians to make jewelry and other objects.

It is representative of enterprise, happiness, and prudence. Chrysoprase is a very popular gemstone for emotional healing and many people use it to promote empathy, forgiveness, growth, and self-love. Wearers of chrysoprase do so to strengthen self-expression and courage along with mental dexterity too. 

It’s a common tool used when a person is recovering from a broken heart or needs to boost their general self-esteem. Unsurprisingly, chrysoprase is not only linked to the heart chakra but it shares the same symbolic green color too. 

The sapphire's colors can vary from the deep blue we’re familiar with, to orange, green, black, and so on. It’s considered a stone of wisdom and a royal stone of learning by many. 

Specifically when it comes in its signature blue color, it brings healing to the mind, order, strength and focus, and can help someone reveal hidden truths. Those who work with chakras use this stone to heal both the throat and third eye. 

It is said that the blue sapphire was worn by King Solomon and Abraham in the Bible. It’s also believed that the tablet of the ten commandments was made of sapphire too. In ancient Greece, Greeks would wear sapphires when visiting the Oracle of Delphi in hopes of revealing hidden truths.  

The birthstones that pair with the Gemini zodiac come with a variety of benefits, each worth checking out if your birthday falls between May 21 and June 20. These crystals and gems are amazing tools for realigning and opening any blocked chakras and are definitely something you should add to your daily rituals and routine. 

It’s important to take time for yourself and with these Gemini birthstones, you can feel grounded, calm, and content as you go through life.
