Diana Maria Fluorite Cluster, Green Cubes - One of a Kind, High Grade

Mined at the Diana Maria mine in England, this small fluorite cluster shows crisp green cubes that shift toward blue green in natural daylight.

That color change is a hallmark of Diana Maria fluorite, and you can test it yourself: look at the cluster on a windowsill in the morning, then again under a lamp at night. The cubic crystals are well formed and grow together in a tidy group. It fits easily in the palm, so it suits a mineral cabinet, a display case or a desk where you can pick it up and turn it in the light. For a fluorite collector, a piece from this English locality is a welcome addition, and it makes a thoughtful gift for someone just starting a mineral collection.

About Diana Maria Fluorite

The Diana Maria mine is part of the Rogerley quarry in County Durham, in the historic Weardale mining district of northern England. It began as a surface operation in 2017 and moved to tunneling in 2018. Fluorite itself is calcium fluoride, 4 on the Mohs scale, and it cleaves cleanly in four directions.

Stone Meaning: Fluorite is traditionally associated with focus and clarity.

Good to Know

• Rogerley fluorite is known for fluorescing in daylight as well as under ultraviolet light, which is behind the blue green shift.
• Many fluorite specimens glow blue violet under UV, so a small UV flashlight is a fun way to explore this one.

Additional Details
