Protective necklace ??

Most necklaces, especially ones in magical shapes like pentacles or ankhs have natural Protective energies and potential. Normally Charging it should be enough. Otherwise, you need to imbue it with several shielding spells depending on what you want to protect from.

What you would probably want to do is program it much like you would program a crystal. Cleanse it by washing in salt water or by smudging with sage or sweetgrass, ect. and then charge it either by holding it in your hand and visualizing white light flooding it, or by leaving it under the full moon. Then you can program it by holding it and, basically, telling it what you want it to do.

search for a spell that makes a necklace

the best thing i honestly would do, wear amethyst, hematite and carnellian they all serve me well,
i hope it helps :D

Hold/cup the necklace in your hands then imagine protective energy (meaning energy specifically for protecting) pouring from your body up down through your arms and out to in your hands and into your necklace. When you think you've poured enough energy into it, "cut off" the energy flow and finish it off. (like when cut off a piece of string and use the rest of it.) Then wola!
see if that works.
