This page brings together the complete list of 20 minerals that start with the letter D, running alphabetically from “Danburite” to “Devilline.” These minerals range from clear, gem-quality crystals to dark metallic ores, and they show up in everything from collectors’ cabinets to industrial and construction use. Some are cut into jewelry, while others are mined as sources of copper, silver, vanadium, or magnesium.
Minerals are naturally occurring solid substances with a definite chemical makeup and an orderly crystal structure. People have valued them for thousands of years, using stones like diamond as both prized gemstones and tough cutting tools. Each one forms under specific conditions deep within the earth’s rocks and deposits.
Below you’ll find the table with the mineral name and a short description of each.

Descriptions
Danburite
A transparent to pale-colored borosilicate mineral often found in clear or yellowish crystals. It is prized by collectors and sometimes cut as a gemstone for its brilliance.
Datolite
A calcium boron silicate that forms glassy, pale green to colorless crystals. It is popular among collectors, especially nodular varieties from Michigan copper deposits.
Diopside
A common pyroxene mineral, usually green, found in metamorphic and igneous rocks. The chrome-rich variety is cut into vivid green gemstones.
Dioptase
A striking emerald-green copper silicate famous for its intense color. Though fragile, its vivid crystals make it a favorite among mineral collectors.
Dolomite
A widespread carbonate mineral made of calcium magnesium carbonate. It forms entire rock formations and is used in construction and as a source of magnesium.
Dravite
A brown variety of tourmaline rich in magnesium. It typically forms in metamorphic rocks and is sometimes cut as a gemstone.
Dumortierite
A blue to violet aluminum borosilicate often found in fibrous masses. Quartz colored by it is carved and polished as a decorative stone.
Diamond
The hardest natural mineral, composed of pure carbon. It is the world’s most famous gemstone and is also used in industrial cutting tools.
Diaspore
An aluminum oxide hydroxide mineral and a major component of bauxite ore. A color-changing gem variety is marketed under names like Zultanite.
Descloizite
A lead zinc vanadate mineral typically forming dark brown to black crystals. It is a minor ore of vanadium found in oxidized lead-zinc deposits.
Djurleite
A copper sulfide mineral closely related to chalcocite. It is a minor copper ore that forms dark gray to black metallic masses.
Domeykite
A copper arsenide mineral with a silvery to tin-white metallic luster that tarnishes quickly. It is a rare ore found in hydrothermal copper deposits.
Dickite
A clay mineral in the kaolinite group formed by hydrothermal alteration. It appears as fine white to pale masses and is used industrially like other clays.
Duftite
A green lead copper arsenate mineral that forms crusts and small crystals. It occurs in the oxidized zones of arsenic-bearing ore deposits.
Dundasite
A pale blue to white lead aluminum carbonate mineral. It typically forms delicate radiating crystal clusters in oxidized lead deposits.
Dyscrasite
A silver antimonide mineral with a bright silver-white metallic luster. It is a minor silver ore that tarnishes to a darker gray over time.
Davanite
A rare potassium titanium silicate mineral. It is of interest mainly to specialist collectors and mineralogists.
Dachiardite
A zeolite-group mineral that forms clear to white fibrous or bladed crystals. It occurs in volcanic rock cavities and is sought by zeolite collectors.
Delafossite
A copper iron oxide mineral with a black metallic appearance. It forms in oxidized copper deposits and is of interest for its electronic properties.
Devilline
A green to blue-green hydrated copper calcium sulfate mineral. It forms small crystals and crusts in oxidized copper ore zones.
