I found one photo of Kate wearing these cute dangle earrings.
She was attending a social event sometime in 2008.
The closeup is from My Small Obsessions.
A large gold piece studded with green stones/beads acts as the earring’s post. Dangling from this is a tri-point elongated gold piece with cut-out, elaborate designs etched into it. From each point there hangs a green bead or stone. These could be jade but I’m not sure.
If anyone can locate the maker of these or a similar pair, please contact me.
