The word "Smaragdite" refers to a mineral that is typically green in color. The spelling of this word may appear confusing at first glance. However, by using the International Phonetic Alphabet (IPA), we can break down the pronunciation of the word. The correct way to pronounce Smaragdite is /ˈsmærəɡdaɪt/. The "dite" ending is common in mineral names, and the "smarag" comes from the Greek word for emerald, which is fitting for a green mineral.
Smaragdite is a mineral that belongs to the amphibole group, specifically a green variety of hornblende. It is named after its remarkable resemblance to the vibrant green color of emerald or "smaragdos," which is where its name is derived from. Smaragdite is a metamorphic rock mineral and forms in the regional metamorphism of basic rocks that experienced high-pressure conditions.
In terms of physical characteristics, smaragdite typically displays a rich green color due to the presence of iron, magnesium, and chromium. It often forms as prismatic, elongated crystals, or fibrous aggregates. The mineral usually exhibits a vitreous to pearly luster and has a hardness of 5 to 6 on the Mohs scale, making it relatively resistant to scratching.
Smaragdite is commonly found in association with other minerals such as actinolite, epidote, garnet, and quartz. It occurs in metamorphic rocks like schist and marble, as well as in ultramafic rocks. It is often regarded as a mineral of secondary origin, formed during the alteration of primary minerals under high-pressure conditions.
Due to its striking green color, smaragdite has occasionally been used as a minor gemstone. However, its use in jewelry is relatively uncommon and it is better known among mineral collectors and enthusiasts for its distinct color and association with metamorphic rock formations.
In summary, smaragdite is a green amphibole mineral, forming under high-pressure metamorphic conditions. It exhibits a rich green color, often resembling emerald, and can be found in association with a variety of other minerals.
A peculiar laminated variety of augite or hornblende, of a bright or emerald-green colour.
