HOW TO VALUE AN AMETHYST GEMSTONE
The value of amethyst, like most gemstones, is determined by the quality (Color, Clarity, Cut and Carat Weight), sometimes by the locality. The bigger finer amethyst can have a high value, typically amethyst is a less expensive gemstone, this partly due to how much is available worldwide.
COLORS OF AN AMETHYST GEMSTONE
From very light almost pinkish purple (Rose de France) to deep rich bluish purple; heat treatment can be done to lighten color or change it to citrine.
WHERE ARE AMETHYST GEMSTONES FOUND?
