This beautiful amethyst cluster has large and very dark, well formed amethyst points. some of the tips of the large points have some clarity with phanotm patterns inside. The points are quite tall, some of them are 5cm thick measured from the base to the tip of the point. This is a very high grade of amethyst, higher than A grade due to the colour and clean formation of the points. The highest grade of amethyst is sometimes referred to by the uruguan exporters as 'extra grade' or 'super grade'. This is a quite large cluster, measuring 8cm x 7cm x 5cm
