These remind me of colourful paper cranes somehow!
EVERYTHING here is of the Spinel family. The difference between Black Spinel and Onyx is that the Spinel is very very sparkly, like black diamonds.
The colourful marquise bits are from the colourful spectrum of Spinel. I have tried to use various shades here, light purple, dark purple, blue, hot pink, pale pink, plum etc.
Wires and all are goldfilled while the leverback ear wires are 925 silver. You can request for goldfilled leverback at an extra $5.
