This page brings together 15 minerals that start with the letter E, ranging alphabetically from “Elbaite” to “Ettringite.” These minerals come in a wide range of colors and forms, from vivid gemstones to soft, soluble crystals. Many are valued as gemstones or collector’s specimens, while others serve as ores for metals or play a role in everyday products.
Minerals are naturally occurring solid substances with a specific chemical makeup and an orderly internal structure. People have used them for thousands of years, shaping them into tools, jewelry, and pigments long before modern science explained how they form. From the deep green of emerald to the bright pink of erythrite, their colors have fascinated cultures around the world.

Descriptions
Elbaite
A colorful variety of tourmaline prized as a gemstone, occurring in shades of green, pink, blue, and multicolored “watermelon” crystals. It forms in granitic pegmatites and is widely used in jewelry.
Enstatite
A common magnesium-rich pyroxene mineral found in igneous and metamorphic rocks, as well as in many meteorites. It ranges from colorless to greenish-brown and is part of the rock-forming pyroxene group.
Epidote
A green to yellowish-green silicate mineral that forms in metamorphic and hydrothermally altered rocks. Its distinctive pistachio-green color and good crystals make it popular with mineral collectors.
Epsomite
A soft, water-soluble magnesium sulfate mineral, commonly known as Epsom salt. It forms in caves, mineral springs, and arid soils, and has long been used in bath soaks and medicine.
Eudialyte
A pink to red ring-silicate mineral found in alkaline igneous rocks, especially nepheline syenites. Rich in rare elements like zirconium, it is sometimes used as an ornamental stone.
Erythrite
A striking pink to crimson cobalt arsenate mineral, often called “cobalt bloom.” Its vivid color serves as a useful field indicator for the presence of cobalt and nickel ores.
Euxenite
A black, rare-earth-bearing oxide mineral containing elements like niobium, titanium, and uranium. It occurs in granite pegmatites and has been mined as a minor ore of rare earth metals.
Edenite
A calcium-rich member of the amphibole group, typically found in metamorphosed limestones and igneous rocks. It ranges from colorless to greenish or brown and is mainly of interest to collectors.
Emerald
The prized deep-green gem variety of the mineral beryl, colored by traces of chromium or vanadium. One of the most valuable gemstones, it is mined notably in Colombia, Zambia, and Brazil.
Embolite
A silver halide mineral combining chloride and bromide, regarded as an intermediate between chlorargyrite and bromargyrite. It forms in the oxidized zones of silver deposits and serves as a minor silver ore.
Eclogite
A dense, high-pressure metamorphic rock composed mainly of red garnet and green omphacite pyroxene. Though technically a rock, it is often listed among striking specimens for its vivid colors.
Eosphorite
A pink to brownish manganese aluminum phosphate mineral found in granite pegmatites. Its attractive crystals make it a sought-after collector’s mineral, often associated with rose quartz and tourmaline.
Erionite
A fibrous zeolite mineral that forms in volcanic rocks and sediments. While naturally occurring, it is notable for being hazardous, as its fibers can pose serious respiratory health risks.
Euclase
A rare beryllium aluminum silicate prized as a collector’s gemstone, occurring in colorless, pale green, and beautiful blue crystals. Its name reflects its tendency to cleave easily.
Ettringite
A colorless to yellow calcium sulfate-aluminate mineral that forms in altered limestones and in hardened cement. It is important in the study of concrete chemistry and durability.
