Elton, at a bash for Chopard in
Liz Hurley, Maggie Gyllenhaal and Eva Herzigova were some of the others at the store launch on Madison Avenue.
Elton, though, was the guest of honour for the evening.
The company has worked with the musician on events for his AIDS foundation.
He said: "I'm here in a small capacity, returning a favour to them for a very big favour they do for us. They're great people and great humanitarians."
This branch is the 100th and largest shop to open.
"Because Elton tours so extensively, he can't sit in on some of the key music decision-making moments, so I act as his eyes and ears," Furnish said.
Meanwhile across the pond, when asked if life has changed since he and David Furnish became domestic partners, the songster's reply was:
“I don’t think it makes any difference, because we’ve been together for 13 years, and now we’ve been together for 14 years," he said. Still, the entertainer admitted, "It feels so much better, to be honest.”
He said he talks to the filmmaker on the phone 10 or 12 times a day.
Asked about the murder of his friend Linda Stein (whose personal assistant confessed to the crime), Elton had less to say.
“I’m not here to talk about that."
He added that he would speak out at the appropriate time.
