Pink
One of the most popular shades of gemstone behind white and black is pink. With an elegant and classy look, the pink gemstone holds a sense of femininity, flirtiness, and pizazz. The pink gemstone never seems to go out of style, and big sectors of consumers desire this stone as much (if not more so) than the white gem. Earring studs are especially high in demand for the pink gemstone. Not adding these to your inventory would be detrimental for any jewelry business, as pink gemstones are sought after in just about every occasion from graduation to wedding to anniversary and beyond.
