I'll start by telling you about E6000. E6000 is what jewelers choose most often. It is one part epoxy, (no mixing) and comes in a tube. This is perfect for attaching findings to metal and costume jewelry. Use it on bead strands to cover end knots. It is strong and flexible and won't become brittle. E6000 is safe with just about every type of gemstone, and works good on vinyl, leather, wood and canvas. It bonds to both porous and non-porous materials. This does not bond well with rubber. It is non-corrosive and sets in 5-10 minutes. In 24 hours it will harden to a clear and waterproof cure. It dries like rubber and dries clear.
There are a couple of things E6000 won't do; bond two pieces of glass together and it can sometimes pull the foil off of the back of acrylic rhinestones.
There is a glue that is called 527 glue, it's the same as E6000 but it is thinner and has a smaller, pointier nozzle for better control.
Loctite 409 gel is used for projects with irregular surfaces. Overall strength is high. It dries in seconds and dries clear. Projects which require instant bonding, such as gluing round beads onto a flat, vertical surface. It has special gap-filling and non-running qualities which is key when working with small beading projects. Has a fine tip applicator so you get the glue right where you need it.
I have read that super glue is frowned upon for use in making jewelry. It is said to ruin rhinestones and other pieces. It breaks easily because it dries like glass, which in turn breaks like glass. However, I do use super glue for some things. I seal end knots, coat a frayed strand and use it on crimp beads. It is also good on plastic pieces.
Aquarium glue would be good for gluing two smooth surfaces of glass.
Clear cements like G-S Hypo Tube or Watch Crystal cement, doesn't dry as fast as super glue, so you have more time to reposition what you are working on. And this bonds strong like super glue. It is good to use for sealing knots, it is water proof and temperature resistant.
Experiment with your glues first, before you use them on your final project. No one glue works with every project. You will probably have to use more than one type of glue to use with all your different types of projects
