Quartz from San Cristobal, Municipio Suaita, Santander Department, Colombia. (Nº-103).

Tessin habit quartz transparent and rich in faces.

We can distinguish a very narrow face by the discontinuity of the striations seen through the crystal.

Tessin habit crystal is the result of repeated alternating termination and prism faces forming a tapered crystal with striated faces.
