Light transmission - subtranslucent to opaque
Luster - a silky sheen that is improved markedly by cutting and polishing
Breakage - subconchoidal to irregular
Miscellany - chatoyant in a broad sense -- this is aptly described by Webster (1986) as follows: “A polished surface ... when turned towards the light often shows a series of lustrous bands alternating with bands of duller colour which show little silkly lustre. The beauty of the effect is enhanced by the fact that the fibres are not always perfectly straight; they may be curved and often have a sharp bend or twist at a certain place. [And,] a change in the incident light results in a reversal of the conditions, the dark bands becoming lustrous and the lustrous bands becoming dark.”; magnetic -- many of these gemrocks are attracted to a magnet because they commonly include bands (i.e., zones), which are typically thin and discontinuous, of magnetite.

Black star diopsid (sterndiopsid) Астеризм (в минералогии) — оптический эффект в кристаллах некоторых минералов, обработанных с образованием сферической или другой выпуклой криволинейной поверхности (кабошонах), проявляющийся в наблюдении звездообразной фигуры при освещении кристалла.
