Is it persmissible to sell a gold necklace with a cross attached to it?
It is not permissible to sell the cross even if it is sold with a necklace. However, if the seller intends and agrees with the buyer to sell them the gold material of the cross and not the shape itself, and the seller ascertains that the buyer will change the shape of the cross to something else, then it is permissible to sell it.
