How to Use Cancer Crystals for Healing

For those learning how to use healing crystals, you’ll quickly see there are lots of options. Finding your ideal method requires trusting your instincts. Luckily, Cancer intuition is strong! 

If you’re wondering where to start, though, we have some ideas you’ll love.

Wear Cancer Gemstone Jewelry

Wearing a Cancer jewelry stone is the simplest, most stylish way to feel your crystal’s benefits. Choosing what crystals Cancers should wear depends on which benefits you’re after.

An aquamarine or labradorite Cancer crystal necklace can encourage new beginnings, while a black tourmaline or selenite Cancer crystal bracelet will bring comfort and protection from negativity.

Chakra Healing

Emotional issues often indicate one of your chakras is blocked. Crystals can act as chakra stones for opening a blocked chakra and getting your energies balanced again. 

The chakras connected to each Cancer stone are:

Recite Crystal Mantras

Before you make your Cancer crystal kit, we should talk about why to use zodiac crystals in the first place.

Why Use Crystals for Cancer?

Astrology can give you insight into your role in life, while healing crystals support your pursuit of that purpose. Before you can understand how to fully benefit from zodiac crystals, you’ll need a basic understanding of astrology. 

The first place to start understanding your chart is the “Big Three” signs: sun, moon, and rising/ascendant.

Your sun sign, based on month-and-day birthdate, describes your general nature and inherent strengths. Those born from June 21 to July 22 have a Cancer sun!

Moon signs represent the more private self, who you are when nobody’s around. You’ll need your birthday and location to calculate your moon sign.

Your rising sign is the first impression you give to others. This sign was on the horizon when you were born, so you’ll need your birth time to calculate it. 

Interpreting a Cancer sun, moon, or rising is easier when you understand Cancer’s place in the zodiac calendar.

Cancer in the Zodiac Calendar

Cancer zodiac dates, between June 21 and July 22, start on the summer solstice. As the rush of Gemini season’s summer party vibe fades, Cancer’s more intimate gatherings begin. This is a time to appreciate those closest to you, preferably (for Cancer) at home away from the crowds.

Check out the Cancer zodiac groups for more insight:

  • Element: Water | Sensitive, intuitive, understanding
  • Modality: Cardinal | Instigating, opportunistic, engaged
  • House: 4th House | House of family, home, and childhood
  • Planet Ruler: Moon (traditional and modern)

As Cancer’s ruling astral body, the moon represents the consistency and comfort this sign craves. Ironically, the moon also represents the ebbs and flows of emotions, which any Cancer is (sometimes begrudgingly) familiar with. 

Many things about Cancer zodiac signs revolve around the comfort and safety of home, represented by ruling the fourth house. The fourth house governs your foundation — your family, roots, and connection to how you grew up.

Speaking of Cancer sign traits, what is the personality of a Cancer?

Cancer Traits: Sun, Moon, and Rising

The main Cancer zodiac sign traits are being devoted, sensitive, and comforting. 

What are Cancer’s weaknesses?

Cancer’s fallbacks are moodiness, isolation, and neediness. With such an influx of emotions, Cancers can easily get crabby or self-isolate instead of opening up. This sign’s nurturing nature is often not equally reciprocated, which can lead to clinging or being passive aggressive.

What does a Cancer moon sign mean?

Cancer moons are the ultimate Mom Friend: sentimental, nurturing, and incredibly protective. These are the people who devotedly create heartfelt, memory-filled scrapbooks. 

Having a Cancer moon means you can easily guess what anyone around you is feeling, which is probably both eerie and comforting to your loved ones. You feel more deeply than any other moon sign, and unlike Cancer suns, you tend to be more open about your feelings. 

What does a rising sign in Cancer mean?

Cancer risings have a skill for intuitively knowing what people want, making them great salespeople or entrepreneurs. 

Cancer rising signs often come off as reserved or stoic, but this is typically from apprehension and a need to “feel out” new people. They’re generally family-oriented, clinging firmly to the past and the people they care about. 

Regarding the past, do you know the traditional Cancer birthstones?

Cancer Month Birthstone Crystals

Your official Cancer birthstone depends on if your birthday falls on the June or July side of Cancer dates.

Let’s look at each June Cancer birthstone:

  • Alexandrite: Rare color-changing green and red chrysoberyl variety symbolizing intellect, luck, and the harmony of opposites.
  • Pearl: Organic gemstone (made by an animal) typically cream-colored and associated with femininity, longevity, and the moon.
  • Moonstone: Internally blue-glowing feldspar mineral used for encouraging personal growth, balancing emotions, and relieving stress.

What about July Cancer birthstones?

  • Ruby: Among the four precious gemstones, this red corundum stone represents prosperity, passion, and courage.
  • Onyx: Layered chalcedony mineral, typically black or green, popular for protection, concentration, and self-control.

While every Cancer crystal birthstone is useful, moonstone for Cancer is particularly powerful. Besides the obvious lunar association, moonstone gently supports your intense emotions while connecting you to your inner god or goddess.

You Can Do it All With Cancer Crystals!

Whether you opt for one of our Cancer crystals or a Cancer birthstone ring, your zodiac stones can support your journey toward becoming who you were meant to be. By embracing your strengths and taking time to reflect, you can connect more deeply to your purpose and to the connections you share.

As Cancer sun Meryl Streep said, “The great gift of human beings is that we have the power of empathy, we can all sense a mysterious connection to each other.”
