On April 15, 2016, Kate hiked up the Himalayas and stopped by a trinket shop. She purchased these earrings for about $7.
The ones on the right are a turquoise version which are similar to Kate’s. They feature a very elaborate four point design on top of an oval pendant made of what I believe to be brass and lapis lazuli (Anna of MSO believes they are lapis as well). Golden circles sit next to each other to form a chain at the bottom of the pendant, and in the center of this “chain” is a round, bordered golden disc, Blue beads dangle from the very bottom of the pendant by golden connectors.
Here they are on Kate:
