What it evokes

In tradition, coral is a talisman of the sea: it was hung around children’s necks and on the prows of boats, and recent books credit it with protection and confidence.

Pliny reports that the Gauls adorned their swords and helmets with coral, before demand from India made it scarce among them; he notes that a branch hung around a child’s neck was believed to keep the child safe. Kunz adds that, to keep its role as an amulet, coral must not be worked.

It is not a stone: it is the skeleton of marine colonies, those of the Mediterranean having declined sharply. No encouragement to buy here: Versana advises against acquiring coral whose origin is unknown.

The traditions

  1. Rome, 1st century

    Pliny describes coral as a shrub that is green under water, whose white berries redden and harden in the air. He writes that the Indians prize it as much as the Romans prize pearls, and that their soothsayers hold it to be an excellent amulet. Before that, the Gauls adorned swords and helmets with it. A branch around a child’s neck was believed to keep the child safe.

    Pliny the Elder, Natural History, XXXII, 11 (Littré translation)
  2. Sailors’ amulet

    Kunz reports a fragment of a Greek lapidary, probably from the 3rd or 4th century, listing seven amulets for seafarers. The fifth, a coral, was fixed to the prow of the ship with straps of sealskin, and kept the vessel safe from winds and waves on all waters.

  3. Italy, tradition reported by Kunz

    Kunz writes that in Italy, to keep its role as an amulet against spells, coral must not have been worked and was worn in view; broken, its pieces lost their power, as if the spirit of the stone had fled. Peasant women believed it paled in certain seasons. He sees in this animistic ideas.

A gestureIf you already own some, keep it away from water, salt, and heat, in a case, like an object of history.

The real dangers of crystals

Nuances and sources

Bamboo or sponge coral, sold dyed, is not red Mediterranean coral, and other corals, black, blue, or white, are other species with distinct statuses. Many corals in the trade are dyed, resin-impregnated, or reconstituted, as the site’s profile points out. Links to signs and chakras vary by author.

Coral: your questions

Is coral a protected species?

Red Mediterranean coral, Corallium rubrum, does not appear in the CITES appendices: its listing was rejected in 2007 and again in 2010. Four Pacific red corals have been in Appendix III since 2008, at China’s request. In the Mediterranean, its harvest is regulated by the Barcelona Convention and the GFCM: not before 50 m of depth, no colony that is too thin. Versana does not recommend buying it; ask about the origin.

How can you recognize real coral?

Natural red coral has a slightly uneven color and a low hardness, 3.5: it scratches easily. Plastic and glass are more uniform, and dyed bamboo or sponge coral imitates red coral. Only a gemological lab settles it, and the seller must disclose dye and resin.

Does coral withstand seawater or salt?

No: coral is calcium carbonate, which salt, acids, and perfumes attack, and the site’s table advises against water, salt, and heat. Wipe it with a soft, dry cloth, and avoid household products. It also scratches on contact with any hard stone.
