Smithsonite was named after Jamos Smithson (1754-1829). He used his legacy to establish the Smithsonian Institute in Washington.

Pure Smithsonite is a white to gray mineral with attractive color due to containing trace impurities. It is used as decorative materials or as a treasure.

Although it may be yellow, brown or pink, the translucent blue-green variety is the best.

It can be polished with the diamond method. Smithsonite is a carbonate mineral. Like all carbonate minerals, Smithsonite is characterized by low hardness and foaming in acid.

Basic properties and characteristics of Smithsonite

1) Mohs hardness: 4-5.

2) Density: 4.30-4.45g/cm.

3) Optical property: inhomogeneous body, uniaxial crystal, negative optical property; They are often heterogeneous aggregates.

4) Refractive index: 1.621~1.849.

5) Gloss: glass luster.

6) Color: green, blue, yellow, light yellow, pink, brown, gray-white, etc.

7) Transparency: translucent to slightly transparent.

8) Chemical property: foaming in case of hydrochloric acid.

Chemical composition

The chemical formula of Smithsonite is ZnCO3, which can contain a small amount of Fe, Mn, Mg, Ca, and even trace amounts of Co, In, Pb, Cd, etc.

A small number of other metal elements replace zinc in the composition.

The color changes with the replacement metal: copper replacement is green to green blue, cobalt replacement is pink, and replacement is yellow.


The Smithsonite belongs to the trigonal crystal system, which is a roughly rhombic crystal, and can have rhombohedron, compound trigonometry and hexagonal prism.

Crystals are rare, usually in the form of dense lumps, stalactites, ribbons, kidneys or granular aggregates.

Physical characteristics

The color is often white or gray or even colorless, but some can be yellow, brown, light blue, pink, green and blue-green.

Smithsonite has below physical characteristics:

  • with glassy luster to sub glassy luster
  • semi-transparent to sub translucent
  • often heterogeneous aggregate
  • uniaxial negative light
  • refractive index N= 1.849, N=1.621
  • birefringence is 0.225 ~ 0.228,
  • the aggregate is not measurable
  • dispersion is 0030
  • there is no polychrome
  • UV fluorescence is no maximum
  • the color varies depending on the origin.

For example:

  • It produced in Japan are blue,
  • It produced in England are rose red,
  • It produced in Georgia are brown
  • It produced in Spain are blue and white, and so on.

Smithsonite has no characteristic absorption spectrum and bubbles when it meets hydrochloric acid.

  • Three groups of rhombohedrons are completely cleaved, 
  • With multilamellar to uneven fracture, 
  • Mohs hardness of 4-5, 
  • Density of 4.30 ± 0.15 g/cm, 
  • Brittle.

Origin of Smithsonite

Smithsonite mainly occurs in the oxidation zone of lead-zinc sulfide deposits and is a secondary mineral.

It is formed by the metasomatism of the original zinc minerals, especially sphalerite, and can coexist with hemimorphite, galena, limonite, etc.

As a secondary mineral of zinc, Smithsonite has been found in many areas and can be used as decorative material, but its production area is relatively small.

The most famous producing areas of translucent blue-green Smithsonite are Russia, England, Australia, Greece, Colorado in the United States, Kelisha in Magdalena, New Mexico, Chumeb in Namibia, Santander in Spain, etc.

Others, such as Japan, Algeria, Sardinia, and Italy;

The Smithsonite in China is mainly produced in the oxidation zone of Lanping lead-zinc sulfide deposit in Yunnan Province.

It is bell-shaped, and its interior is nearly concentric. The texture is composed of white, yellow, yellow-green and other layers of different colors.

Other places such as Guangdong, Guangxi, Shaanxi, Hunan, etc.

Key Points for Identification

There are many colors of Smithsonite, which should be identified in terms of color, shape, size and texture.

Pure white and bright yellow are the best, light green and brown yellow are the second, and black is the worst. The kidney-shaped, bell-shaped and grape-shaped ones are more meaningful than the main, shell-shaped and block-shaped ones, and have certain ornamental and collection values.

Generally speaking, the larger the block, the better, and the stronger the texture. It is an important raw material of zinc ore when it accumulates in large quantities, and its zinc content is 2-3 times higher than that of primary ore.

Smithsonite is a zinc carbonate mineral, which belongs to the calcite group in mineralogy and mainly occurs in the oxidation zone of zinc-bearing sulfide minerals.

It belongs to the Trihedral crystal system and is rhombohedral crystal, but it is very rare.

They are usually grape-shaped, bell-shaped and block-shaped aggregates.

Most smithsonite crystals are translucent, with Glass luster to pearl luster. The minerals in different places show different colors due to their different trace elements;

For example:

  • New Mexico produces blue and blue-green crystals; 
  • The Namibian Chumeb produces yellowish, pink and green crystals; 
  • Italy produces bright yellow smithsonite stalactites; 
  • There are honey yellow blocks in Yunnan and Guangxi, China.

At the same time, due to different origins, under ultraviolet light, there will be different color fluorescence reactions.

The Smithsonite can also be used as carving material in addition to being polished into arc-shaped and faceted gemstones.
