Quartz crystals and masses may have the same luster as calcite, but quartz does not exhibit cleavage and will not react with dilute acid. Quartz is also much harder than calcite. It cannot be easily scratched by a nail and quartz will easily scratch a glass plate. Chert: Chert is a rock composed of very small microscopic quartz crystals.

In general, however, Sphalerite is known for its bright and attractive luster, which is one of the features that makes it such a desirable mineral for collectors and enthusiasts alike.

Non-metallic luster could indicate any other group. However, some of the sulfide minerals are non-metallic, notably sphalerite, orpiment, realgar and cinnabar. The last three are identified by their bright colors. Not many minerals can appear either metallic or non-metallic. Hematite and sphalerite are the most common.Luster: Metallic, opaque: Streak: Lead gray: ... Pure sphalerite samples can be distinguished from galena because they are harder (3.5 to 4) and have a lower specific gravity (3.9-4.1). The color of their streak provides an even simpler way to distinguish the two. A sample of galena rubbed across a rough, hard surface leaves a lead gray streak ...Sphalerite’s dispersion (fire) is about four times that of a Diamond! Because of its high dispersion, adamantine luster and incredible colors, it is one of the most beautiful of all cut gems. It is available in yellows, oranges, reds, browns, greens and black.
