The Earring Curator has dated this piece to the Georgian era.
Brilliant cut gemstones didn't appear until later and the old cuts didn't sparkle as much as modern stones so it gave them a little help. Practically, it just means you should keep them away from water to avoid it leaking behind the stones and damaging the foil - don't wear them to go swimming or do the washing-up!
