	Chrome Diopside - english
		Chrome diopside is mostly available in small sizes: in the rare large sizes, the colour actually becomes so rich that it is too dark.
		But for bright green accent stones, chrome diopside is ideal.
		Chrome diopside is mostly mined in Yakutia and Siberia.

	DIOPSIDE Chapter17. Inosilicates - chain silicates
		Diopside is the dominant clinopyroxene at both Franklin and Sterling Hill; in addition, it is found in moderate abundance in the marble quarries.
		Diopside from the Franklin and Sterling Hill orebodies is white to light brown; it may be colorless in the Franklin Marble.
		Diopside is common to many of the high-temperature assemblages of the calcium-silicate units at Franklin and Sterling Hill (Figures 12-19, 12-20, 12-24, 12-25, and 12-28).

	Diopside
		The material, which is associated with franklinite, is known locally as "white schefferite" and yields a ratio near that of diopside with a little manganese in place of some of the magnesium.
		Diopside and some of its subvarieties are named in all the older lists of Franklin minerals, and many specimens so labeled were seen in the older collections.
		A specimen from Sterling Hill, in the Roebling collection, proved, however, to be a pseudomorph of tremolite after a pyroxene of diopside habit, and the original may well have been diopside.

	Diopside
		Diopside is part of the pyroxene group (straight=single chain silicates), as are jadeite, spodumene, enstatite, and another dozen or so minerals with unappealing names, such as hedenbergite, and kosmochlor, which are not significant for the gem industry.

		For (Ca,Sr)-tremolites the lattice parameters a, b and ß are linear functions of composition and increase with Sr-content whereas c is constant.
		For the diopside series all 4 lattice parameters are a linear function of composition; a, b, c increase and ß decreases with rising Sr-content.
		The observed splitting of the OH stretching band in tremolite is caused by different configurations of the next nearest neighbors (multi mode behavior).
