What it evokes

Recent books link it to communication and calm: it is said to be chosen to speak without getting carried away, or to keep an even mood while traveling.

This reading is old. From antiquity, beryls whose tint recalled a calm sea were esteemed, and a fragment of a Greek lapidary cited by Kunz gives them the role of a talisman for those who traveled by boat. The name aquamarine, “seawater,” keeps the memory of it.

Today it is worn as a memory of the shore: a pale color to think of patience and measure.

The traditions

  1. Rome, 1st century

    Pliny writes that several authors hold beryl to be of the same nature as emerald, and that the most prized are those that imitate the green of a calm sea. He also cites “sky-colored” beryls, but never the name aquamarine, which is later.

    Pliny the Elder, Natural History, XXXVII, 20 (Littré translation)
  2. Greece, 3rd–4th century

    Kunz cites a fragment of a Greek lapidary describing seven sailors’ talismans. The third is a beryl “transparent, brilliant, of a sea-green tint,” which Kunz identifies with aquamarine: it is said to ward off fear, while the first, a carbuncle with a chalcedony, prevents drowning.

  3. The 1912 list

    The American list of 1912 makes it the alternative stone for March, next to heliotrope. Kunz also notes that, in the Second Temple, the high priest’s shoham stone is said to have been an aquamarine.

Nuances and sources

Pisces, Aquarius, or Gemini: recent lists hesitate, but readily place it at the throat among the chakras. It is the only pale blue beryl to bear the name aquamarine, morganite being pink and emerald green.

Aquamarine: your questions

Aquamarine, emerald, and morganite: are they the same stone?

Yes and no: they are three varieties of beryl, a beryllium aluminum silicate. They differ only in their impurities: iron gives aquamarine its blue, chromium or vanadium the green of emerald, manganese the pink of morganite. Their hardness is identical, between 7.5 and 8.

Can an aquamarine be dark?

Natural crystals are often pale blue. A very deep tint can come from heating: a green-blue beryl becomes blue under controlled heating, which is common and accepted in the trade. Imitations, such as blue topaz or glass, also exist. Ask the seller whether the stone is natural, heated, or synthetic.

How do you care for an aquamarine?

It is hard and tolerates water, salt, and light. Wash it in lukewarm soapy water with a soft brush, then rinse. Avoid strong heat, sharp knocks, and household cleaners. Ultrasonic cleaning suits only a stone without fissures or filling.
