โก Quick answer
Smaragdine is a rare adjective meaning emerald-green, of, relating to, or resembling an emerald. It names the deep, glowing green of the gemstone itself. Pronounced smuh-RAG-din.
๐ง Memory trick: Smaragdine hides smaragd, the old word for emerald. If it glows the green of an emerald, the fancy word is smaragdine.
What does smaragdine mean?
The definition of smaragdine is beautifully simple. Historical dictionaries such as Webster’s Revised Unabridged (1913) list it plainly:
Smaragdine (adjective): of or pertaining to emerald; of an emerald green.
Picture a Colombian emerald under a jeweler’s lamp, that deep, vivid green. Smaragdine turns that exact shade into a word. Writers reach for it when plain green feels too flat.
โ “Morning light turned the harbor water a smaragdine blue-green.”
โ “She wore a smaragdine silk gown to the evening gala.”
โ “The forest canopy glowed smaragdine in the filtered sunlight.”
โ “His eyes held a strange smaragdine flash by the firelight.”
Origin of smaragdine
Smaragdine crossed three ancient languages to reach English. The trail begins with Greek smaragdos, meaning a green gemstone. Latin borrowed it as smaragdus and built the adjective smaragdinus, “relating to emerald.” English adopted that adjective as smaragdine.
The word emerald grew from the very same root, through Old French esmeraude, so smaragdine and emerald are ancient cousins. The word’s most famous moment is the Smaragdine Table of Hermes Trismegistus, the legendary emerald-green tablet said to carry the precepts of alchemy.
“Smaragdine comes from Latin smaragdinus, from smaragdus, from Greek smaragdos, a green gemstone.”
“The Smaragdine Table of Hermes Trismegistus is the word’s most famous literary appearance.”
How to use smaragdine correctly

The tricky confusions
Smaragdine vs emeraldine, which is the real word?
Both are real, but they live in different worlds. Emeraldine belongs to chemistry, it names a form of the polymer polyaniline. It is not a general word for emerald-green. For the color, smaragdine is the word you want. And be honest: smaragdine is absent from Merriam-Webster and Cambridge online, it survives in historical dictionaries and word lists. Merriam-Webster does list emerald as an adjective meaning “of a rich green color”; see Merriam-Webster’s entry for “emerald”.
โ “The lake shimmered an emeraldine green.” โ โ “The lake shimmered a smaragdine green.” (Emeraldine is a chemistry term, not a color word.)
โ “The lab studied the emeraldine salt of polyaniline.” (The word’s real home, chemistry.)
Don’t mix up smaragdine with “smaragd” the noun
In Middle English, smaragd was a noun, an old word for the emerald stone itself. The endings look alike, but the jobs differ: smaragd names the gem, smaragdine describes the color. Near-miss pairs like this are a specialty, see our insure or ensure guide for another one.
โ “She inherited a flawless smaragdine from her grandmother.” โ โ “She inherited a flawless emerald from her grandmother.” (The noun is smaragd, not smaragdine.)
โ “Medieval jewelers called the green gemstone a smaragd.”
