This is a top-of-the-line glue that bonds water clear with fast setting time (2 hours). Epoxy 330 is made for bonding gem materials to metal findings. It can also be used for invisible bonding of glass, china, ceramics, stone metals, and other non-porous materials.  It is great for all your projects that you wish to have bond long term and not yellow. It will harden in 10 minutes under a heat lamp.
