Many Faces / Moonstone, Sterling Silver, Brass, & Copper 3-in-1 Necklace

This is an exciting one--I had been thinking about the concept for a while, worked on a different failed version for a week, and then finally came up with this...and I'M IN LOVE!
 
This 3-in-1 necklace features three layers of different metals with three different hand-drawn designs. The first is sterling silver with a layered triangle engraving; the second is heat-patinated copper, which  flashes a neon rainbow in the light, with a criss-cross design; and the third is brass with a radiating torn sunburst design. Peeking through the center cutout no matter what layer you're on, is striking hexagon of rose cut white moonstone. All of the layers hang on jump rings around a bar that leads to a handmade, adjustable bar chain necklace with hexagonal clasp details. Flip between the layers to match your mood, outfit, or just as a cool party trick--this necklace is truly one-of-a-kind!
