Raw facet and cab grade amethyst with good color and clarity. All natural and untreated. Total weight is 36.15 grams (180.75 carats). In workable sizes. As with all amethyst rough, there are areas of inclusions and some banding to be worked around. All 4 pieces for the money. This quality goes for $1.00 a carat at other online sites, so this is a very good deal.
