XL Super Rich & Bright SW + LW + SW Phosphorescent Willemite, Calcite & Franklinite Slickenside Ore - Sterling Hill Mine, Ogdensburg, New Jersey!

Very Large & High Quality Daylight Piece with 3 Different Slickenside Faces Composed of Glossy Black Franklinite (Type Locality), Willemite & Calcite, Plus Amazing Fluorescent Patterns & Super Bright Colors Too!

Very Few Slickensides of This Size & Quality Escaped the Ore Crusher, Since These were Prime Zinc Ore! The Vast Majority of Slickensides have Only 1 Slickenside Face, so This is a Very Rare & Special Piece!

The Willemite is Bright Green under SW UV & Slightly Duller Green under LW UV, and is also Very SW Phosphorescent Too! The Calcite is Bright Red/Orange SW Only.

Locality: Sterling Hill Mine - Ogdensburg, Franklin / Ogdensburg Mining District, Sussex County, NJ, USA
Weight: 7 lbs. 4.5 ozs.
Approximate Dimensions: 7.75" x 4.75" x 3.3"

Pics 7-8 Show the Shortwave UV Response, Pic 9 Shows the SW Phosphorescence at 20 Seconds After Turning Off the Light, and Pic 10 Shows the Longwave UV Response. All Fluorescent Pics were Taken with a 35w WayTooCool SW/LW light.

Fluorescent Response Will Vary Based on the Strength of Light Used, but Any Decent Light of the Proper Wavelength(s) Will Produce Similar Results.

Please Note: You need a Shortwave (SW) and/or Longwave (LW) Ultraviolet (UV) Lamp / Light to see the Fluorescent Colors as Show in the Pictures! This is NOT the same as a Blacklight, although there will likely be some minimal fluorescent response even from a Blacklight.
