On April 10, 2016, Kate attended a gala fundraiser in Mumbai, India.
She wore these prominent lapis and diamond earrings.
Here is the closeup:
The earrings are set in yellow gold and feature two lapis stones (one oval-shaped and one square-shaped). The two stones are suspended one above the other (square stone on top) and framed with tiny diamonds.
You can see the yellow gold from the back.
These specific earrings are not available on any site I can find. The Kate fashion and accessory documenters used this image as what could have been an early design template for Kate’s earrings. We believe this to be a slightly different version.
This version of the earrings she wears costs $2,900.
I imagine Kate’s earrings are priced around the same amount. Kate’s earrings cost £1,360 or $1,958.
Here they are on Kate.
