- Jadeite is a pyroxene mineral with composition NaAlSi2O6. It is hard (Mohs hardness of about 6.5 to 7.0), very tough, and dense, with a specific gravity of about 3.4. It is found in a wide range of colors, but is most often found in shades of green or white. Jadeite is formed only in the subduction zones of continental margins, where rock undergoes metamorphism at high pressure but relatively low temperature.

Star maps show Aquarius as a young man pouring water from a jar or amphora, although Ovid, in his Fasti, says the liquid is a mixture of water and nectar, the drink of the gods. The water jar is marked by a Y-shaped asterism of four stars centred on 4th-magnitude Zeta Aquarii, and the stream ends in the mouth of the Southern Fish, Piscis Austrinus. Who is this young man commemorated as Aquarius?
