In a small saucepan, heat the water, pomegranate juice, and sugar over medium heat until the sugar dissolves and starts to simmer. Stir occasionally. Turn the heat off and add in the pomegranate seeds. Let the syrup cool for at least five minutes before adding it into the cocktails.

You can serve this two ways. The first way is to pour the syrup into the bottom of a pitcher. Pour the sparkling water and lemon in and then stir. Add ice. Pour into individual glasses and garnish with more ice, lemon slices, and a few pomegranate seeds.

The second way you can serve this, which is pictured, is to add a tablespoon or two to each individual glass. Mix the lemon juice and sparkling water together in a pitcher. Pour the lemon water over the syrup, add ice, lemon slices, and a few pomegranate seeds to each glass and then serve. The pomegranate syrup will stay on the bottom of the glass until mixed in.
