Broken Carnelian Teardrop Pendulum

Hello.

My pendulum got washed. It broke when I pulled out my laundry. It's in pieces: stone, chain, and top (stone was glued to top). The stone is chipped at the tip.

My questions are:
Can I still keep the stone even though it's chipped? (In my culture if my jade bracelet is broken, cracked, or chipped; it's bad luck to continue wearing it.)

Has it lost it's powers? Healing properties?

Thank you for your time.
