Where to find Bumblebee Jasper
Mount Papandayan, West Java, Indonesia
The primary and currently only known commercial source of Bumblebee Jasper. It is found in the active fumarolic vents of this stratovolcano.
Collecting tips
- Geological Context. Look for areas with active or recently active volcanic activity, specifically fumarolic fields where sulfur-rich gases and fluids are present. The material is typically found in veins or pockets within altered volcanic ash and rock.
- Color and Pattern. Identify the characteristic yellow (sulfur), black (hematite/ilmenite), and white/gray (anhydrite/ash) banding or swirling patterns. This is the most distinctive visual identifier.
- Hardness Test (Caution Advised). While not a definitive field test due to its composite nature, the material is relatively soft (Mohs 2-4). However, due to the presence of sulfur, direct handling and testing should be done with caution.
- Odor. Freshly broken or cut pieces may emit a faint sulfurous odor, especially if the sulfur content is high. This is a strong indicator of its composition.
Quick Check
- Color:
- Vibrant yellow, orange, black, white banding/swirls.
- Luster:
- Dull to waxy.
- Streak:
- Yellow (for sulfur-rich areas), reddish-brown (for hematite-rich areas), white (for anhydrite/ash areas).
