The moon is the ruling planet of Cancer, and moonstone, being closely associated with the moon, is deemed to be the planetary stone for Cancer. This gemstone for Cancer is believed to stimulate clairvoyance, as well as cure anxiety. See also Moonstone: Stone of Security.

Pearl is a Cancer birthstone, in both Western and Vedic astrology, that also reminds people of the moon. White round pearls are the birthstone for June in both the Ayurvedic (old Indian) calendar and the Arabic, and this Cancer birthstone has kept its place as June birthstone in the contemporary Hindu calendar, as well as the modern Western calendar. Unlike other gemstones, this Cancer stone is a product, not of geological activity, but of marine mollusks, who coat sand or other foreign irritation that had lodged itself inside their shell, giving birth to the shiny round Cancer gemstone. The lucky stone for Cancer is believed to strengthen relationships and marriage, as well as keep children safe.


Aventurine is Cancer birthstone according to author D. J. Conway. Beside white, green is Cancer’s color, making aventurine a fitting birthstone for Cancer, as well as an inexpensive yet beautiful alternative for emerald. Aventurine is a variety of chalcedony known for its shimmering iridescence caused by platy inclusions. This Cancer stone is believed to relieve anxiety and fear, and can indeed be quite helpful to the sensitive and impressionable Cancer.


In the ancient Arabic, Polish and Russian calendars, chalcedony is a birthstone for July, in which month Cancer people are born. The opaque to translucent variety of quartz, chalcedony itself is deeply associated with the Cancer zodiac sign. Though actually occurring in numerous varieties including carnelian, onyx and chrysoprase, the name chalcedony commonly refers to white, bluish white or blue chalcedony. This birthstone for Cancer is attributed with roughly the same metaphysical properties as moonstone. Chalcedony is believed to absorb only positive energy, and repel negativity as well as nightmares. The latter Cancer birthstone is indeed helpful in making the often apprehensive Cancerian feel more secure and optimistic.

Thus straddling the months July and August, ruby is more likely to be a Leo birthstone than a birthstone for Cancer. Ruby is the same mineral as sapphire, however, just a different color. Since sapphire is the talismanic stone for Cancer, ruby may well be a Cancer gemstone too, in which case, both ruby and sapphire are gemstones for Cancer and Leo alike.
