EMERALD NECKLACE

This emerald  strand is from Colombia.There is a silver plated clip on it so its ready to wear.Natural stones but oiled.

 Size  of largest piece 10 x 7 mm app

Weight  110.65 app

Length of beads: 18 inches.

 Emeralds are a variety of the mineral beryl  colored green by trace amounts of chromium and sometimes vanadium.

 Beryl has a hardness of 7.5–8 on the 10 point Mohs scale 

Emerald tends to have numerous inclusions and surface breaking fissures. Unlike diamond, where the loupe standard, i.e. 10X magnification, is used to grade clarity, emerald is graded by eye. Thus, if an emerald has no visible inclusions to the eye (assuming normal visual acuity) it is considered flawless.  Stones that lack surface breaking fissures are extremely rare and   therefore almost all emeralds are treated, “oiled”, to enhance the   apparent clarity. Eye-clean stones of a vivid primary green hue (as   described above) with no more than 15% of any secondary hue or   combination (either blue or yellow) of a medium-dark tone command the   highest prices. This relative crystal non-uniformity makes emeralds more   likely than other gemstones to be cut into cabochons rather than faceted shapes.
