Stunning leaf drops sterling silver necklace

Cubic zirconia, perfect for weddings, holidays, proms, formals etc! Elegant and feminine. Purchased in the early 2000s from a dress store! Make an offer or bundle for discounts! Added pictures to show it has range of wear on the settings - close to collar bone at the tightest setting or down lower at the lowest (but still a “higher” look). I believe it is stirling silver or silver - there is no 925 on the necklace but when I tested it against a magnet it does not stick to the magnet (which I read means it’s usually stirling silver or real silver). It may be old enough that it was before the 1999 rules or putting 925 on jewelry.
