An unusual combination piece from the well-known Champion Mine in California. This cabinet-sized specimen is dominated by nicely formed Quartz crystals up to 3.2 cm and numerous, tan-colored Svanbergites (a relatively rare strontium aluminum phosphate sulfate hydroxide). These are good Svanbergite crystals for the species, and there are micro Rutiles and hard-to-distinguish Topazes to add to the mineralogical interest. Most mining for Andalucite and Rutile was done in the 1920's and 30's, with the Andalucite being used for making high temperature ceramics. Unusual!
