Evening Emerald

Evening

Evening is the period of a day that begins at the end of afternoon and overlaps with the beginning of night. It starts when the sun is close to the horizon and, according to most definitions, spans the period of night before bedtime or midnight. The exact times when evening begins and ends are subjective and depend on location and time of year. In some cases, evening is considered to begin during daylight; before sunset.

Emerald

Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium or sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds have many inclusions, so their toughness is classified as poor. Emerald is a cyclosilicate. It occurs mainly in association with quartz, muscovite, albite, mica schist, Pyrite schorl, microcline, fluorite, smoky quartz and elbaite.

Shades of green

Varieties of the color green may differ in hue, chroma or lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a green or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
