Golden Celtic Knot - Glow in The Dark Necklace

This beautiful necklace is made of gold plate over stainless steel, so it will not tarnish and is sturdy, waterproof, and hypoallergenic. The gold plate may thin over time, so it might turn a bit more silvery with use.
I hand plated it with UV resin pigmented with a non-toxic earth mineral that glows in the dark. All the colors you see are actually from the mineral. 
Any light will charge the mineral (daylight or a regular flashlight). However, UV light will charge it the fastest.
Certain colors glow for longer than others, but fully charged, it will glow at varying intensity between 5 - 12 hours. 
Greens and aqua blue glow the longest and purple dims quickest.
The chain legnth on this model is 18" with extra extender links to 22"
