Just take a cutting, or use the cuttings left from when you prune your jade for shape.
You can also just use a leaf. Just put the end that was attached to the plant into the soil a bit and it will grow roots and start a whole new plant.
Welcome to the forum! We're glad to have you with us! It would be nice if you posted some pictures for us to share the success you have with your jade starts.
