About This Crystal
Polished sphere displaying vibrant yellow, orange, brown, and black banded patterns resembling the coloration of a bumblebee, with translucent to opaque areas and a smooth, vitreous to waxy polished luster.
Physical Characteristics
Colors include bright yellow, orange, black, and white; streak is white; fracture is uneven to sub-conchoidal; specific gravity is approximately 2.6 to 2.9; tenacity is brittle; exhibits no notable magnetism.
Optical Properties
Binds microcrystalline quartz and calcite, generally opaque to translucent, doubly refractive where crystalline, with no notable pleochroism or chatoyancy.
Hardness & Durability
Origin Region
Mount Papandayan, West Java, Indonesia
Hardness & Durability
Mohs hardness ranges from 5 to 7 depending on the localized ratio of softer calcite/sulfides to harder quartz; brittle and sensitive to acids due to carbonate and sulfur content.
Care & Maintenance
Clean with a soft, damp cloth; avoid harsh chemical cleaners, prolonged direct sunlight, and acidic substances; do not use ultrasonic or steam cleaners due to mixed mineral porosity and softness.
Rarity & Value
Uncommon to Rare; value depends on color contrast, pattern vividness, and polish quality; price ranges from moderate for small carvings to high for large decorator spheres.
Special Characteristics
Contains toxic mineral inclusions such as arsenic sulfides (realgar/orpiment) and sulfur, requiring proper safety precautions when cutting or polishing raw material.
Lore & History
A relatively recent discovery from Indonesia popular in modern crystal healing circles; traditionally associated with the solar plexus chakra, confidence, transformation, and joy, though these are entirely symbolic beliefs.
