UV-Reactive Green Cubic Fluorite on Matrix – Zhejiang, China – 1.82 lbs

A substantial UV-Reactive Green Cubic Fluorite specimen from Zhejiang Province, China, featuring dense coverage of intergrown crystals across a natural mineralized matrix. The specimen combines rich sea-green coloration, bold cubic geometry, layered crystal growth, and a contrasting fluorescent response in a highly displayable cabinet-sized formation.

Under ordinary lighting, the fluorite ranges from pale mint and translucent aqua to deeper emerald green. Numerous cubic crystals overlap across the specimen, creating a complex three-dimensional surface rather than a simple flat plate. Several larger cubes establish the primary architecture, while smaller secondary crystals fill the spaces between them and extend the crystallization across multiple sides.

Many crystal faces exhibit stepped growth patterns, fine surface textures, naturally frosted areas, and reflective geometric windows. Selected edges and thinner zones transmit light particularly well, revealing internal color zoning and variations in transparency. The pale cream-to-brown natural matrix remains exposed along the base and reverse, providing strong contrast with the green fluorite.

Under the photographed ultraviolet illumination, portions of the formation display a pale blue-white to soft lavender fluorescent response. The brighter reactive areas outline smaller crystals and layered growth features, while the deeper green cubes form dramatic blue-toned silhouettes under the UV lamp. Fluorescent color and intensity may vary according to UV wavelength, lamp strength, ambient lighting, exposure, and camera settings.

Measuring approximately 3 × 3 × 5 inches and weighing 1.82 pounds, this is an impressive cabinet specimen with excellent crystal coverage and several attractive viewing angles. Its combination of saturated green color, abundant cubic crystallization, visible growth structure, substantial weight, and UV activity gives it strong appeal for both fluorite specialists and fluorescent-mineral collectors.

About Zhejiang Fluorite

Fluorite is a calcium fluoride mineral celebrated for its extraordinary range of colors and its ability to form sharply geometric crystals. Although fluorite belongs to the cubic crystal system, its perfect cleavage follows octahedral directions. This means that natural contacts and cleavage surfaces may appear triangular or angled even when the surrounding crystals display classic square faces.

The cubic habit is especially prominent throughout this specimen. Repeated stages of crystallization produced larger foundational cubes followed by smaller overlapping crystals and stepped surface growth. These later generations give the formation its dense architectural texture and allow it to reflect light differently from nearly every viewing angle.

China has produced many internationally collected fluorite specimens, including significant green cubic material from Zhejiang Province. Zhejiang fluorites may occur in a variety of colors and habits, with some specimens displaying cubic, modified cubic, etched, or complex intergrown formations.

Fluorescence occurs when a mineral absorbs ultraviolet energy and releases part of that energy as visible light. In fluorite, the response may be influenced by rare-earth elements, trace impurities, structural defects, and different stages of crystal growth. Not every crystal or growth zone will necessarily react with equal intensity.

Fluorite is brittle and possesses perfect cleavage. Handle the specimen by its solid matrix rather than individual cubes, and protect it from impacts, sudden temperature changes, acids, harsh chemicals, and prolonged exposure to strong direct sunlight.
