Huanggangliang Teal-Blue Fluorite Cluster, 642 g

Meet a fluorite cluster that reveals more as the light moves. In ordinary room light, this Huanggangliang specimen leans towards deep green and teal. Introduce a little light from behind and its translucent edges glow blue, tracing the clustered crystals like the petals of a flower.

Follow those pale edges across the surface and discover rounded forms stacked closely together, with overlapping layers and darker centres adding depth. The bouquet-like silhouette gives this blue-green fluorite from Inner Mongolia, China its distinctive character: there is plenty to explore beyond a single striking colour.

Bring the crystal details into view

Enjoy the rich green tones in softer light, then use gentle backlighting to reveal brighter blue and turquoise edges. Look closely at the layered surfaces and the contrast between translucent rims and deeper teal interiors. It is a compelling piece for a display cabinet, especially if you enjoy studying crystal shapes and photographing minerals under different lighting.

A closer look at the form

Although fluorite belongs to the cubic crystal system, this specimen does not present as a simple row of separate cubes. Its closely overlapping crystal forms create rounded outlines and a flower-like arrangement. Here, “flower-like” describes the appearance of the cluster rather than a separate mineral variety.
