I buy my earrings in many different places. I really enjoy the selection at Barney’s New York and Neiman Marcus and Neiman Marcus Last Call.
I purchased my all time favorite pair at Barney’s for my birthday. They are the Centaurus Star Studs by Ileana Makri. Ileana and Jon A at Barney’s were kind enough to discuss the weight (under 4 grams with the clamps on!) and special order them. I had them made in 18k yellow gold with yellow diamond pave. The combination of the yellow gold and yellow diamonds give a neon effect . Also, they are neutral and I can wear them year round.
They are 16mm, almost as big as a dime. The sales people at Barney’s NY at Beverly Hills are especially helpful. They will send additional photos if requested. Ask for Jon A!
My best purchase of the year was made at Last Call! I was able to purchase a pair of multi color sapphire studs by Marco Bicego. The earrings are also under 4 grams with clamps on. The best part is that they are almost the size of a nickel.
Online, I like to buy from The RealReal and Oak Gem and Gilt. I ESPECIALLY LOVE that The RealReal and Oak Gem list earrings weights as well as dimensions. They provide the weight in grams. Just be sure to read the return policy in the event you change your mind!
