The Cancer birthstone is a fascinating subject, encompassing more than a single gem. While pearl is traditionally recognized as the primary birthstone for those born under the sign of Cancer in June, ruby, moonstone, carnelian, onyx, and even alexandrite are also considered to resonate with this water sign. These gemstones are valued not only for their beauty but also for the emotional and spiritual qualities they are believed to bestow upon the wearer. This article will explore the history, lore, gemological properties, and symbolism associated with these Cancerian birthstones, drawing upon available information to provide a comprehensive overview.
History and Lore
The association of gemstones with the zodiac signs dates back centuries, with roots in ancient astrology and belief systems. For Cancers, born between June 21 and July 22, the chosen stones reflect the sign’s nurturing, sensitive, and intuitive nature. Pearl, as the traditional June birthstone, has a long and storied history. Its origins are intimately linked to the ocean, forming within mollusks as a response to irritation – a fitting metaphor for the Cancerian tendency to transform challenges into something beautiful.
Ruby, while more commonly associated with July, also holds significance for Cancers. Its fiery energy is believed to ignite passion and courage within the often-reserved Cancer personality. The inclusion of moonstone, carnelian, onyx, and alexandrite further expands the range of stones considered beneficial for those born under this sign, each offering unique properties to complement the Cancerian temperament. These stones are thought to provide emotional stability, foster calm, and enhance a sense of inner peace.
Geological Formation and Sources
The formation of these Cancerian birthstones varies significantly. Pearls are unique in that they are organic gemstones, created within living organisms. They form when an irritant, such as a grain of sand, enters the shell of a mollusk – be it a clam, mussel, or oyster. The mollusk then coats the irritant with layers of nacre, a shimmering substance, over months or even years, resulting in a pearl. Pearls are sourced from both saltwater and freshwater environments across the globe.
Rubies, on the other hand, are mineral gemstones, formed through igneous processes. They crystallize from aluminum oxide in metamorphic and igneous rocks. Ruby deposits are found in various locations worldwide, though specific sources are not detailed in the provided materials.
Carnelian, a variety of chalcedony, forms in sedimentary and volcanic rock. Onyx, another chalcedony variety, also originates in these geological settings. Moonstone forms in igneous and metamorphic rocks, while alexandrite, a rare variety of chrysoberyl, is found in metamorphic rocks. The sources of these stones are not specified in the provided materials.
Gemological Properties
The gemological properties of these Cancerian birthstones are diverse, reflecting their different compositions and origins.
- Pearl: Pearls are not graded using the traditional “4Cs” (cut, clarity, carat, color) like diamonds. Instead, their value is determined by luster, nacre quality, shape, size, and surface perfection.
- Ruby: Ruby’s color ranges from pinkish-red to deep crimson, caused by the presence of chromium. Its hardness is 9 on the Mohs scale, making it a durable gemstone.
- Carnelian: Carnelian exhibits a range of colors from pale orange to deep reddish-brown, due to iron oxide inclusions. It has a hardness of 6.5-7 on the Mohs scale.
- Onyx: Onyx is a banded chalcedony, typically black and white, though other colors exist. It has a hardness of 6.5-7 on the Mohs scale.
- Moonstone: Moonstone displays a characteristic adularescence, a shimmering effect caused by light scattering within its structure. Its hardness is 6-6.5 on the Mohs scale.
- Alexandrite: Alexandrite is renowned for its color-changing ability, appearing green in daylight and red under incandescent light. It has a hardness of 8.5 on the Mohs scale.
A comparative table of hardness is shown below:
| Gemstone | Mohs Hardness |
|---|---|
| Ruby | 9 |
| Carnelian | 6.5-7 |
| Onyx | 6.5-7 |
| Moonstone | 6-6.5 |
| Alexandrite | 8.5 |

Symbolism and Metaphysical Beliefs
Each of these gemstones carries symbolic weight and is associated with specific metaphysical properties. Pearls symbolize purity, honesty, and steadfast loyalty, resonating with the Cancerian value of deep, meaningful relationships. They are believed to encourage unconditional love and provide soothing sensations during emotional times.
Rubies represent passion, strength, and courage, enabling Cancers to access their inner resilience and overcome challenges. Carnelian is linked to creativity and motivation, providing a gentle nudge towards pursuing one’s dreams. Onyx offers grounding and protection during emotional turmoil, providing stability and strength. Moonstone is associated with intuition and balance, aiding in calming emotions and trusting one’s feelings. Alexandrite is believed to promote emotional stability.
These stones are thought to align with specific chakras, further enhancing their energetic properties. Moonstone is linked to the Crown and Third Eye Chakras, promoting spiritual connection and intuition. Pearl resonates with the Heart Chakra, fostering compassion and emotional healing. Ruby’s energy is also connected to the Heart Chakra, boosting vitality and courage.
Care and Cleaning
The care required for these Cancerian birthstones varies based on their properties. Pearls are relatively soft and porous, requiring gentle handling and cleaning with a soft cloth and mild soap. Avoid harsh chemicals and ultrasonic cleaners. Rubies, with their high hardness, are more durable and can be cleaned with warm soapy water and a soft brush. Carnelian and onyx can also be cleaned in this manner. Moonstone requires gentle cleaning with a soft cloth, as it can be scratched easily. Alexandrite should be cleaned with a soft brush and mild soap, avoiding harsh chemicals.
