    You will get better at knowing over time. But one trick is to go into your modeling software, make two additional copies of your pendant. Center the midpoint of the bail on the Y axis (x=0) in both new models. Create a new cube that is larger than one half of the pendant and completely cover one half of the pendant. Use a boolean join to differ the pendant from the half-covering cube. So now you have a half-pendant split on half the bail. Repeat exactly on the other half model. Load both half-pendants into your models in shapeways. Check the cubic centimeters of each. if they are exactly the same, the pendant should hang straight. If not, adjust a new copy of the full model, split again, etc. until the cubic centimeters mass is the same in both halves.

    Meshmixer can show you the center of gravity.

    The Meshmixer stability tool is excellent. It takes into account the volume and surface area of an object, but keep in mind certain materials will have a differing weight per volume. For example, metal vs plastics vs ceramics.
