Where to find Rose Quartz with Clay

United States
Maine, South Dakota (Black Hills), and California have occurrences of rose quartz, where clay inclusions might be present.

Collecting tips
- Look for Veins and Pegmatites. Rose quartz, including varieties with clay, is typically found in the core zones of pegmatites or within hydrothermal quartz veins cutting through various rock types.
- Examine for Inclusions. Carefully inspect pink quartz specimens for cloudy, opaque, or discolored areas that might indicate clay inclusions. These can range from subtle haziness to distinct patterns.
- Check Hardness. Quartz is hard (Mohs 7). If a pink mineral scratches easily, it is likely not quartz. The clay inclusions themselves will be much softer, but the overall hardness of the specimen will be dominated by the quartz.
Quick Check
- Color:
- Pink to rose-red with cloudy or streaky clay inclusions (white, grey, brown).
- Luster:
- Vitreous to greasy, dull in clay-rich areas.
- Streak:
- White
