When it comes to haute joaillerie, green is the color. Angelina Jolie, Cate Blanchett and Mila Kunis have all been spotted wearing emeralds on the red carpet; the famous Colombian emerald mine Muzo is creating a precious stone brand with top designers like Shaun Leane and Solange Azagury-Partridge; and earlier this year in Hong Kong, Christie’s sold an emerald ring from Afghanistan for $2,276,408 – an auction world record. While Colombian emeralds remain the most sought-after, African stones are coming to the fore, according to Keith Penton, Head of Jewelry for Christie’s: “African emeralds are being used by many of the best jewelry houses in their current designs. I’m sure that in time the best African emeralds will create record prices.” If you’re thinking of investing in emeralds, Penton offers the following advice: “Look for the best clarity and the richest color and avoid opaque or overly pale colored stones with no appearance of life. Above all else, buy something that you love and that you’ll wear. There’s something very sad about jewelry that lives in a bank vault.” christies.com
