Fluorescent Mineral Database

A new secret project! Trying to create a nice Fluorescent Mineral Database (FMDB), which would be searchable by mineral, locality, and luminescence properties. Also making it easy for people to contribute with their own specimens!

Norbergite from the Limecrest Quarry, Sussex County (Franklin Area), New Jersey

Contributed by: Howie Green
Date: Mar 8th, 2026
Locality: Lime Crest Quarry, Sparta Township, Sussex County, New Jersey, USA (See on Mindat)

Description:
Some of the best examples of norbergite are found in the areas around the Franklin, New Jersey, especially at the Limecrest Quarry, Sparta, Sussex Co., where it formed in well-shaped, flesh-colored crystals and yellow to brown embedded grains. The type locality for norbergite is the Östanmossa mine, Norberg, Västmanland, Sweden. Notable occurrences are found in the marbles of Mogok, Burma (Myanmar), sometimes producing large gemmy crystals of norbergite.
