[2]: 248 In addition, Robert Jameson in his fundamental works of 1804-1821 also included hauyne as a separate mineral species[3] and the so-called “calaite”, which in the 1820s meant only turquoise, among the azure feldspars.

[4]: 571–572 All of the listed minerals are known primarily as ornamental stones, and have historically been used as painting pigments and dyes for various purposes.

More than others, lazurite or lapis lazuli has historically had a decorative use, classified by A. Fersman and M. Bauer as a first-order semi-precious ornamental stone.

Haüyne is valued significantly higher than lapis lazuli, but it is rarely found in jewelry quality suitable for cutting.

Finally, lazulite is sometimes used not only as an ornamental stone, but also for jewelry cutting, although finds of high-quality raw materials are too rare for its mass use.
