What does prase mean?
Prase is a specialist name for a translucent green variety of lepidolite, a mica mineral. Although it occurs with other micas rather than as a completely separate mineral species, polished pieces can be used as decorative stones, beads, and small gemstones. Its characteristic color is usually described as leek-green or soft apple-green, and the word is pronounced like “praise.” In mineralogical and lapidary contexts, prase is more precise than a broad term such as green stone: it identifies a particular green mica material, not emeralds, jade, malachite, or every green quartz. Collectors and cutters may favor especially translucent and richly colored material. Outside specialist descriptions, the word is uncommon, so context usually indicates that a gemstone or mineral is meant. Its unusual name and close sound resemblance to “praise” make it especially memorable.
nounA translucent green variety of lepidolite, a mica mineral, sometimes cut and polished as a gemstone. It is characterized by a soft, leek-green color.
- A translucent green variety of lepidolite used as a mineral specimen, ornamental material, or gemstone.
"The jeweller set a translucent prase in a simple gold pendant."
"The cutter set a translucent prase beside the rose quartz."
"Collectors value prase for its soft green color and natural inclusions."
The plural is uncommon; prase is often treated as a mass noun when referring to the mineral or decorative material generally.
"The collection included two rare prases from Brazil."
Prase means “leek-green”—an aptly understated name for a translucent green mica prized for its unusual color.
