Mila Kunis joined Gemfields in New York this week to mark the launch of the colored gemstone miner’s second advertising campaign, themed “Beauty by nature.”

The Ted actress attended an emerald “master class” and evening cocktail party held at the St. Regis Hotel, where Gemfields also celebrated the publication of a coffee-table book it commissioned, simply called Emerald.

Meanwhile, out west, both Centurion and the Tucson colored gemstone shows got underway while British designer Stephen Webster welcomed two street artists for a party at his Beverly Hills, Calif. boutique.
