What is the Cancer Birthstone?

Cancer is the 4th sign of the zodiac. The birthstone for Cancer is the Ruby. Ruby is a precious red gem that means confidence. Those born between June 20th and July 22nd share the Cancer star sign. The Cancer element is water and the zodiac symbol is a crab.


The Sensitive Soul

Cancer’s love their comfort. Make no mistake, this star sign is at their happiest when curled up on the sofa with their besties having an emotionally in-depth conversation. If they aren’t on the sofa, you could also find them kicking back in the bathtub, paying homage to their favorite element of water. Like all the water signs, Cancer’s do not shy away from emotion. They are all about emotional discourse, in-depth conversations, and using their deep intuition to draw out the truth. They love to put their heads together and have a conversation.

All of the above is the exact reason why Cancer’s make such charming and loyal friends. And believe us, they take their friendships seriously. Loyalty is one of the most important traits they value and sometimes this means that they can have equally high expectations of other people’s commitment back to them. For those that are excellent at reading between the lines, you may have noticed that the Cancer zodiac sign is all about wearing their heart on their sleeve and pouring love into the people in their life. This means that they truly do become long term friends forever, but it also means that when they feel slighted or rejected by other folks, they can retreat into their shells just like the crab that represents them. Their sweet and sensitive nature can make them appear a little moody at times, especially when they are working through the big feels they are often battling with.

For those who fall under the banner of Cancer as a star sign, it can be helpful to have gemstones that help when it comes to staying grounded and building that deep emotional resilience. Loyalty, an abundance of love, and the ability to feel all the feels are amazing traits, but Cancer’s should also make sure they are taking care of themselves.

Cancer Birthstones


ruby stone

The deep red glow of the Ruby Stone is one of the traditional birthstones associated with the zodiac sign of Cancer. The Ruby is also ruled by the Sun (and Cancer is ruled by the Moon) and because of this close cosmic connection, Ruby is able to harness the powers of the planet and to bring balance to the life of a Cancer. As the birthstone of Cancer, the Ruby is also known for balancing the heart and bringing confidence, added extras that are sure to help the (sometimes) co-dependent Cancers to stand firm on their own two feet.




The glorious grounding properties of Carnelian also make it an excellent stone for Cancer people. Carnelian is all about bringing a positive glow back to your world and nudges you to be even braver. It helps the Cancer Zodiac sign by bringing out their beautiful artistic flair and ensuring that they stay on track to making the right choices. Find out more about the meaning of Carnelian.




The magic glow of Moonstone is a mesmerizing match for Cancer. This stone illuminates the truth and helps to deepen intuition and guide the way. As Cancers are known for their often spot-on intuition, this stone works to strengthen that skill and leads to a better sense of well-being. Find out more about the meaning of Moonstone.


Rose Quartz 

Rose Quartz

One of the gentlest heart chakra crystals in the world, Rose Quartz is all about compassion, healing, and homing in on high levels of self-love. Blushing pink, the Rose Quartz stone matches that caring side that those who have Cancer as their birth sign hold deep in their hearts. Along with boosting that gorgeous flow of compassion and sending it out where it is needed in the world, Rose Quartz also reduces the web of self-pity and fear-based indecisiveness that sometimes Cancers may sit in. Find out more about the meaning of Rose Quartz.




The luminous beauty of Pearl immediately connects the water element of Cancer making it a much loved lucky stone. These gleaming orbs often found at the bottom of the seabed are a symbol of purity and heartfelt sincerity. This echoes with the authentic heart of those born under the sign of Cancer. Another benefit of having the Pearl close at hand for a Cancer is the fact that it uses its water-like moods to take negative energies and transform them into soft ripples of positivity.




Charming Chalcedony is a chiller making it a great stone for Cancers to keep close by. The quartz-based crystal doesn’t shy away from alignment, making sure that the head and the heart are ever ready to echo each other and helping to cut down on those times when you may be ruminating too much. The gentle stone also knows how to sweep away those sad feelings and takes you out of the blue and into brightness.



Green Aventurine

Amazing Aventurine drives out fear and anxiety making it a great choice for those who share the Cancer sign and who tend to veer a little on the sensitive side. Rather than succumb to those feelings of being easily tarnished by the thoughts, words, and actions of others, the glimmering green Aventurine puts a protective barrier in place so you can take a deep breath and move on. Find out more about the meaning of Aventurine.




With a similar soft sheen to the Pearl and the Moonstone, Opal also brings a luminous touch. This stone is known for its ability to heal old wounds, putting you on the path for pristine emotional healing. For those times when you just crave a little extra compassion from the world, Opal sends those vibrations straight to the heart. It’s a stone that sparks creativity, joy, and a sense of soft joie de vivre at the idea of living life (despite all it’s rough and tumble). 




One of the most protective stones in the pack, Obsidian is all shield. The sweet and soft nature of Cancer star signs means that vulnerability is no stranger here. Fortunately, with Obsidian on your side, you can feel safe and protected no matter what the world throws your way. Snowflake Obsidian is also known for helping you to learn to let go. When it’s time to put down the things that are simply not serving you, this stone will whisper to the wearer's soul. Find out more about the meaning of Obsidian.



Turquoise stones

Plunge right in with the green-blue hues of Turquoise. One of the most soothing stones you ever did see, this ocean bright gem is an instant stress buster. Not only does Turquoise work to keep you calm and collected, but it also helps you to find your true voice and to use it. Never one to overwhelm, it helps Cancers to throw down those boundaries without fear. Find out more about the meaning of Turquoise.




Also known as the Courage Stone, Aquamarine is another wild water element that entices the sometimes changeable and tight-laced Cancers to simply let go. Far from a flighting stone, Aquamarine brings its cooling flow to get you out of a rut and makes sure that you find that innate wisdom to pick which stream will carry you forth. Find out more about the meaning of Aquamarine.

Keep your Cancer birthstone jewelry cleansed and clear and communicating with their fullest strength. Like all gemstones, each of these crystals can get clogged up with negative energies and toxins they have collected along the way. By running them under clear water or tumbling them with other quartz crystals you can draw out those vibes and find ways to refresh your stones. As Cancer is water energy, you can be sure that the associated stones also love the kiss of H2O. After cleansing, you can also charge them up by leaving them under the light of the moon.

Final Thoughts on Cancer Birthstones

Cancer birthstones bring luck, healing properties, and harmonious prosperity to your world. By acknowledging where your strengths sit and where you could be lifted up, these stones work with your own personality and the power of the planets to manifest a magical environment for your inner peace to thrive. For Cancers, it's super important that they take the time to sit with themselves and nurture those root chakras so they keep themselves feeling strong, independent, and safe. All these stone amulets can help to ground, protect, and provide a safe space for your voice, spark, and soul to bloom.
