I have used 8 mm peridot semi-precious gemstones in a lovely olive green colour.
They look great with bronze beadcaps, bicone and small round beads.
The earrings hang on bronze wires, and have a drop of around 3 cms / 1.25 inches as measured from the base of the earwire.
Your earrings will be supplied in an organza gift bag.
Alternatively they would fit within a small gift box that can be purchased from my shop http://folksy.com/items/4594561-Small-black-gift-box-earring-and-small-pendant-size
