Collecting tips
- Look for Igneous Outcrops. Focus on areas with known rhyolitic or aplitic intrusions or extrusions, as these are the typical host rocks.
- Examine for Distinctive Pattern. The unique black-on-white speckled pattern is the primary identifier. Look for this characteristic visual signature.
- Check Hardness. While not a true jasper, its hardness is generally around 6-7 on the Mohs scale due to its quartz and feldspar content, which can help differentiate it from softer rocks.
Quick Check
- Color:
- Cream to light gray with black spots.
- Luster:
- Dull to vitreous.
- Streak:
- White (for the matrix), black (for the spots, if powdered, but generally not practical for a rock).
