Massive white barite (also called known as baryte) looks like marble and could be used for decorative purposes. In spite of the abundance of good crystals, cut barites are not commonly seen, especially in rich colors.

Gem cutters will find faceting barite difficult. Facet junctions tend to be rounded. Collectors can obtain large stones in almost any desired color with very few exceptions.

Identifying Characteristics


Barite can display weak pleochroism if the crystal is colored.

  • Brown crystal: straw yellow/wine yellow/violet.
  • Yellow crystal: pale yellow/yellow-brown/brown.
  • Green crystal: colorless/pale green/violet.


In shortwave ultraviolet light (SW):

  • White (Germany, Ohio).
  • Blue-green (Germany, England).
  • Gray (Germany).

In longwave ultraviolet light (LW):

  • Greenish white, yellow-green (Germany)
  • Pinkish white (Ohio).
  • Cream-white (South Dakota).

Stone Sizes

Large crystals, usually flawed, have many facetable areas. English material will yield stones up to about 50 carats. (One specimen is known to be over 300 carats). Faceters have cut yellow-brown crystals from France as large as 65 carats. Colorado gems range from 1 to 5 carats.

Notable barites in private collections include:

  • A 42-carat golden-orange, cushion cut gem (British Columbia).
  • A 108-carat dark brown, oval cut gem (South Dakota).


Due to this stone’s perfect cleavage and low hardness, jewelry use is very risky. Consult our gemstone jewelry cleaning guide for care recommendations.
