This very edgy and unusual material is SUPERCONDUCTOR from the Texas Supercollider. Copper, Zinc, and Niobium is twisted together. Each piece is DIFFERENT because of where it's sliced from the cable. This material has been a huge hit in my shop for the science minded.

My customers have been asking for pieces of this for Men. From the right an inch, middle just over an inch, and the left almost 2 inches. Each piece has bits of the grey running through copper.

**Here are the new shapes! 7 of them. The ones to the right look darker, but are not, it's lighting.
If there is a shape you prefer, just ask for it in your notes to seller.
Here is a link about the Supercollider this wire is taken from:

Thanks for looking! Back to my shop:

I make hearts, earrings, pendants, and rings out of this material, Superconductor wire. They are a different listing.

♥I'd like to thank my neighbor Steve who is a physics genius for lending me his books for the
photo shoot!
