Mix the adhesive according to the manufacturer's instructions.
Apply masking tape to the back side of the filigrees. This will prevent the adhesive from leaking through the openings.
Apply adhesive to the back side of the flat-back crystal and center it on the filigree. Press gently in place. Repeat with the second filigree and crystal.
Set the pieces aside in a warm area to cure. Curing overnight is usually best.
Once cured, remove the masking tape from the back side of each filigree piece.
To finish each earring, simply add an earring hook to the top of the filigree piece. Twist open the earring loop, add the filigree, then twist the loop closed.
