If the leaves are still fresh and green you can leave them on. Otherwise strip the leaves off. (They'll be decorated with ribbon anyway.)
Push a 2-inch lollipop stick into the top of each of the strawberries, leaving an inch or so showing.
Melt the chocolate:
Heat water in the bottom of a double boiler and place the dark chocolate chips and vegetable shortening in the top. (You can also place a large heatproof bowl over a saucepan of water.) Heat the water to a simmer, and stir the chocolate chips until they are smooth and melted.
Cover the strawberries:
Dip the strawberries one at a time into the chocolate, as deep as you can while holding onto the stick in the top. Allow excess chocolate to drip off and then set each dipped strawberry into the waxed paper-lined dish.
Add the sparkle:
While the chocolate is still wet, sprinkle the strawberries first with a bit of the pearl dust, and then with some of the sanding sugar. Continue this way until all of the strawberries are decorated.
Loosely cover the dish with plastic wrap, being careful not to disturb the surfaces of the strawberries. Allow the strawberries to set for several hours in a cool place away from the heat of the kitchen, but do not refrigerate them.
Add the ribbon:
Shortly before serving the strawberries, cut short lengths of silver and gold ribbon and curl the ends. Tie ribbon around the sticks on each strawberry.
Transfer the berries to a platter or festive dish and set them out for your guests. (Preferably in a spot where a little light will hit them and set the glitter sparkling!)
Give the berries enough time to air-dry after washing them. They need to be dry before they are dipped, as any water on the surface would cause the chocolate to seize.
I recommend lining a casserole pan with wax paper to hold the berries after they're dipped. The sides of this pan will be high enough that you can cover the pan with plastic without it touching the wet berries.
It's best to prepare these the day of your event, perhaps in the morning if you are planning an evening party. I don't recommend refrigerating your dipped strawberries: not only can the berries begin to get slimy, the chocolate is prone to grayish streaks when it goes in and out of temperature extremes. Instead, dip your strawberries then give them several hours to set in a cool, room-temperature place.
