For these earrings I drilled the central grey pearl and set it with smaller white pearls that I had put on pegs, along with rubies in 14k gold settings. The thistles drop from gold-filled chain.
The included iridescent pearl stud has a 14K post and oxidized sterling backing, and is a separate piece (a jacket earring). So, if you prefer a different accent you can use any other stud earring as the top to this design.
