The See also:colour is due to the presence of See also:nickel, probably in the See also:form of a hydrous silicate
.
By exposure to a moderate See also:heat, or to strong See also:light, the See also:chrysoprase becomes paler, or even colourless, but it may regain its colour by absorption of moisture
.
Chrysoprase is a See also:mineral of rather limited See also:distribution
.
Most of it comes from the neighbourhood of See also:Frankenstein in See also:Silesia, where it occurs in association with altered See also:serpentine
.
It is found to a limited extent at Revdinsk, near See also:Ekaterinburg, in the Urals; and it occurs also in See also:India
.
It is known, too, at several localities
in See also:North See also:America, notably at Nickel See also:Mount, See also:Douglas See also:county, See also:Oregon, where it occurs in nickeliferous serpentine
.
The chrysoprase of the moderns is certainly not the chrysoprasius of See also:Pliny, or the Xpvalnrpaaos of See also:Greek writers
.
The See also:ancient stone was not improbably our See also:chrysoberyl, and it is doubtful whether the modern chrysoprase was known until a comparatively See also:late See also:period
.
The chrysoprase of Kosemutz, near Frankenstein in Silesia, was discovered in 1740, and used by See also:Frederick the See also:Great in the decoration of the See also:palace of Sans Souci at See also:Potsdam
.
But at a much earlier date the Silesian chrysoprase was used for mural decoration at the See also:Wenzel See also:chapel at See also:Prague
.
Chrysoprase was a favourite stone in See also:England at the beginning of the 19th See also:century, being set See also:round with small brilliants and used for brooches and rings
.
At the See also:present See also:- TIME (0. Eng. Lima, cf. Icel. timi, Swed. timme, hour, Dan. time; from the root also seen in " tide," properly the time of between the flow and ebb of the sea, cf. O. Eng. getidan, to happen, " even-tide," &c.; it is not directly related to Lat. tempus)
- TIME, MEASUREMENT OF
- TIME, STANDARD
time it is said to be regarded by some as a " lucky stone." Much commercial chrysoprase is chalcedony artificially stained by impregnation with a green See also:salt of nickel
