We have discussed this from time to time.
Some people prefer to stick to one color, silver/silver or gold/gold.
Others don't mind mixing gold with silver. I mix them up, as I do with most of my jewelry.
There are several Juicy Couture charm bracelets, not all are the heavy starter bracelets. But the charms are larger & heavier, so the bracelet has to be able to handle the weight.
