Kate notably wore these to an Dublin art gallery opening in 2007.
I’ve been trying to find more photos of her with these earrings, but so far I can only find two.
Here is the close up:
These are clustered pearl (they remind me of a bunch of grapes on the vine) drop earrings attached to a pearl stud which acts as the earring’s post. The cluster of pearls consists of round pearls and teardrop pearls. It looks like any metal attachments on it are in silver or silver tone.
The luster on these pearls makes me think they are cultured and not artificial.
Kate also wore these on a casual outing the same year.
I’m trying to locate the maker of Kate’s earrings. Many jewelry companies do make similar earrings in terms of style, but I haven’t found one that doesn’t have a French hook and instead has the pearl post as you see it on Kate.
