experiment for stormlight jewelry

The gem has an LED inside it; it is connected by the copper chain to a battery on the underside of the wrist. I found some cut glass beads at the craft store with holes big enough for LEDs inside so I started experimenting a bit. I'd rather use a skinnier gauge of wire but this is what I had on hand; now I know the method works I will get some better materials.

Really awesome! I've been trying to find a slave bracelet that looks enough like a soulcaster to make a good christmas present for my friends, but this blows me away. I don't know if you've looked at other designs, but "slave bracelet" searched in Google or Etsy comes up with some cool designs!

Very nice! Next step obviously is to try getting a network of gems going :D

Yup! Because this is battery-powered, multiple gems are slightly more of a challenge, because it has to be a working circuit (and I think the gems have to be connected in parallel if I want to keep the battery small, but correct me if I'm wrong on that) but I have some designs sketched out. I still need to order some white LEDs -- the gems are colored, but right now the only LEDs I have are green.

Yes they would have to be in parallel for more then 3 gems. LED's in series divide the total voltage of the battery across each led (So 9v battery / 3 LED = 3 V) LED's in parallel would divide the total current across the total LED's. I don't know of any high voltage small batteries. That said you should be able to get small button batteries that would fit under each gem and power each gem separately. With a transistor in each circuit you could use a main battery for on off switching with the separate batteries actually powering each LED. Seems like an interesting problem. /*goes to desk to tinker with circuits*/
