Place the citrus fruit, pears, and persimmons into a serving bowl. Squeeze the lemon juice over the top and set aside.
Cut the pomegranate in half horizontally. Working over a bowl set in the bottom of the kitchen sink, hold the pomegranate in your hand, cut-side down. Hit the back of the pomegranate with a wooden spoon. The seeds will fall from the membranes into the bowl. Fill the bowl with cool water. Any of the leftover membranes will rise to the top and can easily be separated from the seeds. Drain and sprinkle over the top of the other fruit.
Sprinkle the fresh mint over the top and serve immediately.
