Foilback is described as:

Explanation:
Foilback refers to how the stone is backed. It’s a backing technique where a thin layer of metallic foil is applied to the reverse side of a glass stone (often a paste or rhinestone) to reflect light back through the stone and boost brilliance. This describes the back treatment itself, not the stone’s material (paste) or its surface luster (vitreous) or the type of stone (rhinestone). So stating foilback is describing the backing method, which is why it’s the best, most precise label.
