The above photo is of a more simple necklace. The single-strand necklace is made up of wire-wrapped labradorite rounds.
A more Steampunk style necklace, the above piece was made out of tiny 3mm Swarovski crystals and old watch gears.
Above is another multi-stranded necklace. This particular piece is made up with small topaz and sapphire coins and rondelles.
