My granddaughter recently had her ears pierced (she was 14 yesterday) and I decided to make her a teeny tiny pair of earrings.
These are simple rings of 2 - 2 - 2 - 2 but with beads added as you can see. There are four at the top of each ring (3 on the outside and 1 on the core thread) and a bead in between each ring.
In the very centre I've added a large bead. Now I'm not sure if this has been documented anywhere but it's quite easy.
As you're closing the second ring you add the large bead to the core thread keeping it close to the first double made of that ring. Secure that large bead with a safety pin/paperclip so it doesn't escape and continue with rings 3 and 4. On ring 5 you have to join to the large bead after you've made the ring (removing the pin/paperclip) and continue to close. It's really simple but I can write/draw it up if you think it's worth it.
