What it evokes
In tradition, pearl evokes purity and modesty: in 1913 Kunz calls it the “queen gem,” opposite diamond, the “king gem,” and modern crystal practice associates it with calm and love.
Its fortune comes first from its rarity. Pliny places it at the top of all jewels, and ancient belief held that it was conceived by a shell opening to the dew of the sky. It is not a mineral: a mollusk forms it, layer after layer, around a grain.
It is kept as a sign of patience, knowing that it fears water, acids, and knocks.
The traditions
- Rome, 1st century
Pliny sets pearls at the summit of all jewels and says they come mainly from the Indian Ocean and the Persian Gulf. He reports the opinion that the shell, in season, opens to conceive a dew from the sky, whose purity decides the whiteness of the pearl. He notes that no two are ever found alike, hence the Roman name unio, “unique.”
Pliny the Elder, Natural History, IX, 54 and 56 (Littré translation) - Rome, 1st century
Pliny tells of Cleopatra’s wager against Antony: she is said to have had a vessel of vinegar served, dropped into it one of her two pearls, the largest ever seen, and swallowed it once dissolved. The story is more tale than record, but it recalls a real fact: vinegar attacks pearl.
Pliny the Elder, Natural History, IX, 58 (Littré translation) - 1913, the king and the queen
Kunz contrasts diamond, the “king gem,” an emblem of invincibility, with pearl, the “queen gem,” an emblem of modesty and purity. Yet in discussing the birthstone lists, he writes that pearl is not a stone in any sense of the word and should not appear there, but that it may be worn as an emblem of purity.

A gesturePut it on last, after perfume and creams, as a pendant or discreet earrings, then wipe it with a soft cloth.
No stone has a proven effect on health: if you have a health concern, see a health professional.

Nuances and sources
A cultured pearl is a real pearl: a bead or a graft is placed in the mollusk, which then forms the nacre. The trade also sells glass coated with “essence of Orient,” plastic, and shaped pieces of mother-of-pearl or shell, which are not pearls. The 1912 jewelers give it for June, with moonstone able to replace it.

Pearl: your questions
How can you recognize a fake pearl?
A common test is to rub the pearl gently against the edge of a tooth: a real pearl feels slightly gritty, while a coated-glass imitation feels smooth. On a strand, each pearl differs a little from the others. These tricks do not replace a lab opinion: a well-made cultured pearl looks a lot like a natural one, and the exact designation matters when you buy.
Can you clean a pearl with water?
The site recommends avoiding water: wipe it with a soft, barely damp cloth after wearing it, without strong soap. Vinegar, perfumes, hairsprays, and sweat dull the nacre, as Pliny’s story of Cleopatra reminds us. Store it flat in a cloth, apart from any harder stone, which would scratch it.
What is the difference between a natural pearl and a cultured pearl?
Both are formed by a mollusk, but a natural pearl arises without intervention, whereas a cultured pearl results from a bead or graft placed by people. The latter dominates the trade. Neither is a mineral: it is an organic material, made of calcium carbonate and conchiolin. A lab can tell them apart, the eye rarely can.
