'The Simple Life' star and the Good Charlotte frontman visited Los Angeles jewelry store XIV Karats on February 19.
Nicole, 25, tried on several ruby necklaces before buying one for half-price at $3,350. The couple then looked at the engagement rings, which were also in the sale.
An employee told Life and Style Weekly magazine: "Of course he would never get her a half-price ring.
"You can tell they're crazy about each other. His arm was around her the entire time."
Nicole, the adopted daughter of singer Lionel Richie, began dating Joel late last year, shortly after he split from actress Hilary Duff.
Just weeks after they began dating, Nicole was stopped by police driving on the wrong side of a California highway after leaving Joel's house.
She told police she had been smoking marijuana and has since been charged with Driving Under the Influence (DUI) but has entered a plea of not guilty.
