How to Identify 10 Red and Pink MineralsThoughtCo

22/06/2019· A transparent mineral that's pale red is a clear mineral that owes its color to impurities. The same is true of all clear, red gemstones (like rubies). Consider the color of a reddish mineral carefully, in good lighting. Red grades into yellow, gold, and brown. While a mineral may show a red highlight, that should not determine the overall color. Also, ascertain the mineral's luster on a fresh,

3 Mineral Properties – Mineralogy

Gold, clear, and pinkish describe color. Transparent describes diaphaneity. Cubic describes crystal shape, a property related to symmetry. These four properties (luster, color, diaphaneity, and shape) are basic for mineral identification. Other properties including streak (the color of a mineral when powdered), the way a mineral breaks (cleavage, parting, fracture), and hardness are also,

5 Optical Mineralogy – MineralogyOpenGeology

But cleavage planes are oriented in three dimensions (3D). So observed cleavage angles depend on grain orientation. If a mineral has two cleavages that intersect at 60°, the cleavages will appear to intersect at any angle from 0° to 60° depending on grain orientation. So we must often examine many grains (or one with a known orientation determined by examining an interference figure) to,
