Cut a quarter of the orange into 2 wedges. Use the wedges to wet the edge of the glass and then dip into the sugar to create a sugar rim. Then squeeze the orange wedge into the glass, it will only be abut 1 to 2 tablespoons of juice.
Take the cranberries and roll them around in the remaining sugar.
In a small pitcher or measuring cup mix the pomegranate juice, agave, and a few pieces of rosemary together.
Divide the juice between the two cups. Fill the rest with the seltzer. Drop in the cranberries.
Put 3 cranberries on a toothpick and lay them on the glass as garnish along with rosemary and a slice of orange. Enjoy.
