NEPTUNITE SPECIMENS

Neptunite is a rare, striking mineral that often captures attention with its deep, glossy black to reddish-black crystals. It is a silicate mineral composed primarily of potassium, sodium, iron, manganese, titanium, and lithium. First discovered in Greenland in 1893, its name is inspired by Neptune, the Roman god of the sea, reflecting its early association with marine deposits.

Neptunite typically forms as prismatic crystals with a glassy luster and is often found in association with minerals like benitoite and natrolite. Its primary localities include the Benitoite Gem Mine in California, which is renowned for producing some of the finest specimens, as well as deposits in Greenland and Russia.
