This cocktail Jewelry trend is presented by Piaget, the renowned Swiss luxury watchmaker and jeweler. Their “Limelight Paradise” collection reinvents the cocktail ring to actually look like cocktails.The tropically colored gemstone rings in green tourmaline, amethyst, and blue topaz are adorned with straws, lemon slices, and even diamond salt on the rim. These cocktail rings differ from the classic work that Piaget has done in the past, in that the rings are designed to actually look like thirst-quenching alcoholic beverages.
