Lot of Great Reposhed Jewelry

I did it again! I over-bought and now I really must re-posh or add a wing to my house! My loss is your gain! Great collection of costume (?) jewelry- vintage for sure! This grouping by color- jade- it looks real but I can’t tell however nothing has been changed, or altered. The bracelets are elastics- the necklace is over-the-head-no clasp needed. Thanks for looking- ask questions please.
