Tabular refers to the habit, or shape of the quartz crystal. Tabular crystals are noteworthy because they are rare. Six-sided spikes with pointed tops are normal shapes, called euhedral crystals. Factors like heat, time, and pressure can affect the shape of the crystal during its growth. Crystals forming flat, blocky, stubby tablet shapes are called Tabular. Faden quartz is a descriptive term for a Tabular quartz crystal with a white thread-like zone running through the interior. The term Faden is a German word for "thread". They are occasionally found in the Alpine region of Europe, Pakistan, Russia, and in Arkansas. We find them in our Sierra Nevada quartz deposit here in California. Tabular crystals with Fadens are very rare in frequency.
When these Faden zones grow, the quartz crystals in them are broken repeatedly, and the healing and regrowth incorporates fluid and gaseous inclusions (the white threads). The edges of the crystals grow faster and incorporate the liquid inclusions in the center of the crystals. The results are stunning in their beauty and forms.
