Very Large & Rare Genthelvite Sterling Hill Mine by Franklin New Jersey - SW + LW UV Fluorescent Ultraviolet Minerals
$299.99
FRN4-07
Very Rare & Quite Large for the Species, Shortwave & Longwave Ultraviolet Fluorescent Genthelvite Mineral Specimen from the Sterling Hill Mine in New Jersey!
A Large, Crude Genthelvite Crystal which was Naturally Etched from the Surrounding Calcite in Situ! It's a Bit Fragile Due to the Fact that It's a Very Thin Specimen, but Safe to Handle Carefully & Display. The Vast Majority of Genthelvites Found at Sterling Hill were Tiny Specks, This is One of the Largest That I've Ever Seen in Person & We've Had a Couple Hundred Over the Years!
Fluorescent Genthelvite (Bright Mint Green LW & Very Dull Light Greenish-Blue SW) with Calcite (Bright Red/Orange SW) & Meionite (Pink SW)
Locality: Sterling Hill Mine - Ogdensburg, Franklin / Ogdensburg Mining District, Sussex County, New Jersey, USA

The First 2 Fluorescent PicsShow the Longwave (LW) UV Response Using a Convoy C8+ 365nm LED Flashlight. The Last 2 Show the Shortwave (SW) UV Response & were Taken with a 35w WayTooCool SW UV Light.
Fluorescent Response Will Vary Based on Strength of Light Used, but Any Decent Light of the Proper Wavelength(s) Will Produce a Similar Response.
*Please Note: Fluorescent Minerals Require a Shortwave (SW), Midwave (MW) and/or Longwave (LW) Ultraviolet (UV) Light for the Fluorescent Response Shown in the Pictures! a Black Light is NOT a SW/LW Light, although Some Rocks May also Show Under Black Light as well!
