description Rubasse Overview
Rubasse is a variety of rock crystal quartz containing dispersed red hematite or other iron oxide inclusions. These inclusions give the otherwise colorless quartz a reddish appearance, sometimes producing patterns or areas of red coloration within the crystal. Rubasse has historical interest as an inexpensive ruby simulant and is collected primarily as an inclusion-bearing quartz variety.
help Rubasse FAQ
What is rubasse?
Rubasse is a variety of rock crystal quartz containing dispersed red hematite or other iron oxide inclusions. The inclusions give the otherwise colorless quartz a reddish appearance.
Why does rubasse look red?
Its red appearance comes from iron oxide inclusions, especially hematite, spread through the quartz. The color may appear as broad reddish areas or as patterns inside the transparent crystal.
Is rubasse a type of ruby?
No, rubasse is quartz rather than ruby. Its red color is caused by included iron oxides, while ruby is a red variety of corundum.
What does rubasse look like in a crystal?
Rubasse can show red patches, streaks, or dispersed internal coloration within otherwise clear rock crystal quartz. The exact pattern depends on how the hematite or other iron oxides are distributed.
