Fluorescent Zircon Crystals in Matrix - Colorado

This beautiful specimen contains chocolate-brown zircon crystals that are still partially embedded in their natural matrix. It was collected from St Peters Dome, Colorado. It displays a stunning yellow fluorescence under short wave UV lighting! There is a red fluorescent mineral that makes up some of the matrix, likely feldspar. The largest zircon crystal measures .3" wide.

This specimen comes with an acrylic display case.

Zircon belongs to the nesosilicates group and forms as tetragonal crystals. Its common chemical formula is ZrSiO4, which can be altered by a variety of impurities. Certain impurities result in crystals with a wide variety of colors (white, colorless, blue, red, green, yellow, orange, brown, pink, purple, and gray). Certain impurities within zircon crystals can be radioactive, but that radioactivity is typically minimal and is generally believed to be safe, without posing any health hazards.
