Description

This is a fine sample of "Fadenquartz". The specimen is developed as floater, sharp terminated and highly lustrous all around. The faces show beautiful texture. The crystal shows a very good clarity with a significant faden in the centre, which is better visible in real life. Also you can see a small green phantom at the top. Much better in person, no significant demages to report.
