Description
This Emerald rough was mined on columbia and it is now ready for facting or cabbing.
Emeralds are a variety of the mineral beryl (Be3Al2(SiO3)6,) colored green by trace amounts of chromium and sometimes vanadium
Emeralds come in many shades of green and bluish green. There is a wide spectrum of clarity, dependent on the inclusions and fractures in the crystal. Clear stones with dark yet vibrant color command the highest prices
Most emeralds are oiled as part of the post lapidary process, in order to improve their clarity. Cedar oil, having a similar refractive index, is often used in this generally accepted practice. ] The amount of oil entering an emerald microfissure is roughly equivalent to the size of a period (full stop) in print[]. The use of green-tinted oil is generally not considered acceptable by the gem trade
This rough is natural but it has been oiled
WEIGHT: 4.60 CTS APPROX.
SIZE:14X8X6 MM APPROX.
