Hi Lois, I’ve worked with those crystals for a couple of years now
and they are beautiful. In your situation, I would get a fairly
fine soft wire and do a wrap around. That way you won’t be risking
exposing the crystal to heat.
What do I mean by a wrap around? You can use a head pin. After
stringing the crystal, be sure you have at least 1/2" of wire left.
Using round nosed pliers make a loop about 1/8" above the bead.
Wrap the remaining wire around the 1/8" part.
Of course you can vary the length of the dangle by the length of the
wrap.
