Phosphorescent Amber Calcite Cluster

Phosphorescent Amber Calcite Crystal Cluster – Guizhou Province, China | 450 g

This remarkable Amber Calcite specimen from Guizhou Province, China, features a dramatic formation of elongated, blade-like crystals in rich shades of golden honey, warm amber, and deep caramel brown. The densely packed crystals rise vertically from a natural gray matrix, creating a striking, architectural formation with beautifully defined crystal terminations.

In natural sunlight, the translucent amber crystals reveal stunning internal layers, warm golden highlights, and brilliant reflective surfaces. Their varying lengths and overlapping formations create wonderful depth and texture throughout the specimen.

What makes this specimen especially fascinating is its phosphorescent behavior! Under ultraviolet light, the amber-colored crystals exhibit a striking pale blue-white luminescence, creating a dramatic transformation from their warm daylight appearance. Exhibits beautiful phosphorescence, transitioning from pale blue-white fluorescence under UV light to a lingering green afterglow once the UV light is switched off.
