What it evokes
Modern crystal guides associate emerald with love and renewal: its green evokes spring, and it is seen as an image of a fresh start or of an affection that renews itself.
The stone has been admired since antiquity for its color. Pliny writes that no green looks green next to it, and that gem cutters rest their eyes on it. In the medieval and Renaissance texts gathered by Kunz, it was credited with stranger gifts: revealing the truth of lovers’ oaths and granting memory and eloquence.
Today it is chosen mostly as a reminder: a green to look at, to think about what you wish to see grow.
The traditions
- Rome, 1st century
Pliny ranks emerald third among the stones: no green, he says, can stand comparison, and it is the only one that feeds the eye without wearying it. Gem cutters use it to rest their sight, and Nero watched gladiator fights through a flat emerald. He distinguishes twelve kinds, the Scythian ones being the most prized.
Pliny the Elder, Natural History, XXXVII, 16-17 (Littré’s French translation) - Middle Ages and Renaissance
Kunz reports that emerald was believed able to reveal the truth of lovers’ oaths and to grant memory and eloquence. He cites Albertus Magnus: the emerald of King Béla of Hungary is said to have broken into three pieces when he embraced his wife. Cardano, for his part, declared himself skeptical that it brings wealth.
Kunz, 1913, “Emerald” entry in the Curious Lore - Modern crystal guides
According to contemporary crystal books, it is linked to love and renewal. These associations are recent and rest on its color more than on any ancient text.

Nuances and sources
Pliny distinguishes twelve kinds of emerald, and his names do not necessarily match ours. Modern lists often link it to the heart chakra and to zodiac signs that vary from book to book: these correspondences, which arose in the 20th century, have no common ancient source.

Emerald: your questions
How can you tell a real emerald?
A natural emerald almost always shows inclusions and fissures. A perfectly clean stone with a very vivid green should raise suspicion: it may be a synthetic or glass. Fissures are often filled with oil or resin, a very common practice: ask for it to be disclosed and, for a valuable piece, for a laboratory certificate.
Can you clean an emerald with hot water?
A soft cloth and lukewarm water are better. Heat damages the oils and resins that fill the fissures of many emeralds, and those fissures then become visible again. So avoid hot water, steam, and drying near a heat source.
Are emerald and peridot the same stone?
No: emerald is a beryl and peridot an olivine, with different colors and compositions. Kunz notes, however, that peridots from Egypt, kept in European cathedral treasuries including Cologne’s, were long mistaken for emeralds. The mix-up in names is an old one.
