Yellow Gold Emerald Flat Back Threaded Stud Earring

Most of my flat backs are from Estella Collection, and I keep coming back for more! They were nice enough to make these emerald studs for me in white gold even though it isn’t a listed option. I got the 3mm, which I would say are great for a second or third hole but too small for a first. I got them to go with emerald chain danglers I have, and I think they look great. I prefer lab grown emeralds because in my experience natural emeralds tend to be lighter and often have inclusions. The only thing I don’t like about these studs is that they’re set in a way that protrudes slightly from the ear, and I prefer a flush fit. The bezel studs I have fit more flush (pictured in my lower helix) but are obviously a different look, and I didn’t want that much gold showing. Estella Collection, please list more white gold options and start offering 4 mm posts :)
