3.8″ Fluorescent Castle with Feldspar


This Colorado quartz cluster exhibits 2 fluorescent minerals.
The quartz grows on feldspar, partly fluorescent and partly not.
The feldspar glows bright pink under shortwave ultraviolet light.
The quartz contains glowing chalcedony, seen as green in the images.
I use a variety of white lights to help bring out the crystal shapes in the pictures.

I bought a batch of these unique crystals in 2005, shortly after they were mined and identified as rarest fluorescent quartz.
There are several pieces available from 1 inch to 100 pounds.
Please inquire for photos, sizes and prices.
Small pieces start at $6 per ounce.
