Named in 1895 by Stens Anders Hjalmar Sjögren in honour of Anders Celsius [November 27, 1701 Uppsala, Sweden - April 25, 1744 Uppsala, Sweden], Swedish astronomer, physicist, and naturalist.

celsian, an uncommon feldspar mineral, barium aluminosilicate (BaAl 2 Si 2 O 8), that occurs as hard, light-coloured, glassy masses and crystals in association with manganese deposits in contact zones, as at Jakobsberg, Swed.; Tochigi prefecture, Japan; Rhiw, Wales; near the Omuramba Otjosondjou (dry riverbed), Namibia; and near Incline, Calif ...

Celsian is a very rare barium-rich member of the feldspar group. This mineral is named after Anders Celsius (1701-1744), a famous Swedish astronomer and scientist who proposed the Celsius temperature scale. Celsian forms a solid solution series with Orthoclase, and the intermediary member is known as Hyalophane. Although sometimes viewed as a ...

Matrix composed by lamellar sanbornite (sa) and granular quartz (q). Rectangular crystal in the upper right corner is titantaramellite (ti) and isometric crystals included in sanbornite are celsian (ce). Location: Trumbull Peak, near Incline, Mariposa Co., California, USA. Scale: See Image. Colorless, Yellow, White.

Celsian is a mineral with formula of BaAl 2 Si 2 O 8 or Ba(Al 2 Si 2 O 8). The IMA symbol is Cls.

Introduction: Celsian, with its captivating hues and metaphysical properties, emerges as a gemstone of rare beauty and profound significance. Found in granite pegmatites and prized for its translucent to transparent crystals, Celsian not only dazzles the eyes but also holds the potential to enhance harmony, creativity, and spiritual growth.
