Terms for subject Jewelry (594 entries)

transparency	The quality or state of being transparent.
Trapiche emerald	Often found in the mines of Columbia, these are the only Emeralds with a naturally occurring star effect. Though it resembles an asterism, a trapiche occurs as the crystal grows and is not a reflection across the surface of the gem. It is within the gem. A trapiche emerald is the result of an emerald crystal that contains the impurity lutite, and as the crystal grows in its hexagonal shape, the dark lutite is pushed towards the center of the emerald creating the star-like effect. The emerald takes its name from the tool, called a trapiche, that Columbians use to grind sugar. It resembles a spoked wheel.
