We offer a lot of choices here when it comes to pendants, drops and charms, but do you really know what the difference is? I congratulate those of you who do. I even had to be reminded what the difference is! Although you can use a charm as a pendant and vice versa, here are the technical differences between the three.
A drop has a top-drilled hole that goes from one side to the other. It does not have a fixed bail, loop or jump ring, and does not need to be modified in order to lay correctly when strung.
Pendants are pieces that are 25mm or larger (not including the bail, loop or jump ring). If it does not have a bail, loop or jump ring, then its hole will be drilled or punched from front to back. If a pendant is smaller than 25mm, it will have a fixed bail or loop. Swarovski is the exception.
A charm is smaller the 25mm and does not have a fixed bail.
