Rock crystal, smoky quartz

A masterfully cut rock crystal – smoky quartz, which in a brilliant cut exactly in the middle divides into a perfectly transparent crystal half and on the other side sharply transitions to a slightly smoky smoky quartz. This unique stone from the West Bohemian pegmatite was cut by Svatopluk Prchlík and was originally in the collection of Josef Cvačka. The size of the absolutely clean stone without any inclusions (64.5 ct) is absolutely unique for this locality.
