A rather sentimental necklace I wear every day. I found the ivory backgammon die in the games room of an abandoned summer camp and represents the gamble of the day to day, the skull is from a broken tibetan skull bracelet of mine and represents the impermanence and transience of life. So you know, embody impermanence and embrace chance.
I used chain from a broken necklace to cage the die, and headpins for the loop at the top and the skull. I think it helps to use larger chain, it ensured I could properly allot just the right amount of chain to tightly encircle the die. Any more and it'd fall out.
