This Willemite is a green fluorescent mineral from the famous Parker Shaft in Franklin New Jersey.
This works great with Longwave UV. Pics taken in Longwave 365nm filtered UV Convoy C8. But it's even better and brighter under 254nm shortwave UV.
The Willemite Dust is ground to a consistent 400 mesh.
Great for resin projects, rings, necklaces, and artwork and even glass blowing!!
