Combine the ginger, sugar, allspice, cloves spices, and crystallized ginger, and 2 cups of water in a medium saucepan. Bring to a boil. Remove from the heat, cover and let steep for 45 minutes. Prepare a large bowl set over an ice bath. Strain the ginger syrup into the bowl, pressing out all the liquid from the ginger. Cool to room temperature.
Just before serving, stir together the ginger syrup and seltzer in a pitcher. Add the lime juice if desired. Serve over ice.
The ginger syrup will keep in the refrigerator for up to one week.
