More than one enchantment? Simply put, yes. However, doing multiple spells on an Amulet-to-be is a little futile. If you plan on having multiple purposes for an amulet, then you should include this into your spell.
If you wanted a pendant for love and beauty, as well as protection, this all should be included into your spellwork and intent. If this is difficult to do, perhaps you are not ready for such a task.
Yes you can but it`s generally a bad idea to do so if it`s one solid piece, but if its a lets use expression composite jewelry(like pearls or something similar) then there should be no problem, because you can place one enchantment per composition(as long as enchantments don`t clash in any way).
To add and to kind of include what the person above me was saying:
Think simplistic, concise. If you are wanting 1 thing for everything that you could need from an enchantment, then thats a lot of energy being thrown around. This is hard on people to produce such energy in conjunction wtih diety (should this be your route). So, try and think simple. Being simple is very clear to the powers that be as well as yourself, and it will ultimately benefit your amulet and the effectiveness of the whole process.
I like that idea though, composite jewelry. This is where charm bracelets and the like come in handy.
Can you have more than one enchantment on a piece of jewelry? Yes. Should you have like many many many of them on the one piece? You could but it isn't recommended.
You should always limit the number of enchantments if they aren't somehow related. Like love, beauty and happiness could all go together. Prosperity and good luck could go together easily. However, you wouldn't want to enchant one item with protection, beauty, love, good luck and balance for your life...you get the point, right?
A charm bracelet, however, can allow you to enchant several pieces each for a different purpose. I had one that I did like this years ago. Worked out real well.
And of course, before you try to enchant a piece of jewelry, you need to study about magick. You need to master all the basics before taking on any enchanting of items or casting spells. Otherwise, you wont have a clue as to what you are doing or how it works.
