Leave the left over on a mixing paper

 

Leave the left over on a mixing paper or plastic, whatever is used to mix the cement and place the mixer(toothpick, paper clip or other handy object) into the unused part. When the object is cemented hard on the unused portion of the cement, you know the jade is also cured and may be handled.

Excess if any may be carefully trimmed with a razor edge or left alone. Trimming of extruded cement will often leave a white and easily seen line. Sometimes it is best to leave the cement as is.

If you have way too much cement and way too much is pushed from the joined edges, clean in acetone or nail polish remover. Clean well as you can. Then start again with a new mix of the epoxy. Do not use "super glue" since this will not hold strongly for a long period of time.

If you want to try to do the work, I believe you can. The first try might be messy and you might have to try a second time. If you want someone else to do it, a jeweler should be able to cement the pieces together for your repair depends on the sort of break in the bracelet. If the jade is broken and the ends of the break fit fairly well, a jeweler (or you if handy with such) may use a good epoxy cement to join the ends. A recommended epoxy is Hughes 330, recommended because it cures water clear and is quite strong with gemstone materials. In any case, epoxy cements have no strength when first mixed. The cure brings the strength. If you try it yourself, dry fit first to find a way to support the pieces during the 2 hour cure time.

If the break is jagged and the ends do not fit, the best solution is to have a jeweler make a metal tube, either of silver or gold, to go over the broken ends and bring all together as a jade bangle with "metal fittings". The tube will need to have two ends angled to fit the curve of the jade pieces at each break.

I do hope the break is clean and will fit back together. If so, with a good cleaning to remove all traces of oils, etc., the epoxy solution to the fix will work quite well. If done carefully, there will be little to show obviously at the break line.
