Yes, it’s kind of silly. No, it doesn’t offer any additional benefits. And yet ... it’s strangely compelling.

We’re talking about the American Express® Gold Card’s limited-edition rose gold option, available by referral until Wednesday, July 17, 2019. American Express’ own description explains it all: “It's a variation on the Gold Card. It has the same great features and benefits, with a stylish hue. Plus, it's metal.”

The only way to get the rose gold variant is via referral from an eligible American Express cardmember. Referrals can be made through the mobile app or this site. Most cards are eligible to generate a referral, except for AmEx’s hotel and airline co-branded cards.

If your friends need some prodding, tell them they can receive 10,000 Membership Rewards points for each successful referral, up to a total of 55,000 Membership Rewards points per year. Terms apply. And as a new American Express® Gold Card holder, you’ll be eligible to receive the following welcome bonus: Earn 35,000 Membership Rewards® points after you spend $4,000 on eligible purchases with your new Card within the first 3 months. Terms Apply.

Whether you get the flashy rose gold version or not, the American Express Gold Card offers valuable benefits for foodies and frequent travelers alike. You’ll earn 4 Membership Rewards points per $1 spent at restaurants (worldwide), 4 points at U.S. supermarkets (on up to $25,000 per year) and 3 points on flights booked directly with airlines or at amextravel.com. Terms apply.

Membership Rewards points are flexible: They can be used to book travel directly, or transferred to a growing list of airline and hotel partners.

The card does carry a hefty $250 annual fee, though it’s somewhat offset by the $100 annual airline fee credit and $120 dining credit (if you make use of it).

All that glitters is not gold — it could be rose gold. But only until Wednesday.
