Beverly Hills Gold on QVC (1989-2004) was noted for fine diamond cutting and filigree work by American jewelry makers. The best known representative for Beverly Hills Gold on QVC was Claudia Hollingsworth.
The Beverly Hills Elegance line on QVC's competitor is made in India, Turkey, among other countries and features natural diamonds in classic and novelty designs. The brand's representative is Ido Levanon who broadcasts from Tel-Aviv. He has not been on QVC and he is not a Spelling (that would be the creator of that other Beverly Hills).
The brands have nothing to do with each other, nor are either of them related to Beverly Hills Polo, Nick Chavez Beverly Hills or The Beverly Hillbillies.
