Pale Yellow Stalactitic Calcite Crystal Cluster from Phong Nha-Ke Bang National Park, Vietnam.
These specimens are pale yellow stalactitic calcite aggregates naturally intergrown with white quartz host rock. The crystals exhibit typical scalenohedral and rhombohedral combined crystal forms. They are translucent with pale honey yellow tint and intense vitreous luster, featuring the characteristic radial clustered growth structure of stalactitic calcite. Color gradually transitions from pale yellow at the core to pale white on outer crystals, with distinct hierarchical crystal sizes including sharp acicular microcrystals and massive individual calcite monomers. All crystals retain intact, full three-dimensional forms with favorable transparency.
