Confetti Gemme. The “main attraction” of the Confetti Gemme Collection are luminous semi-precious stones such as blue topaz, amethyst, rose tourmaline, lemon citrine, and peridot. These bright and luxurious gems are shaped exclusively for Marco Bicego in the smoothest of “Tumble” cuts and are accompanied by his signature hand-engraved golden pebbles. With its beautiful combination of colors and gold, Confetti Gemme evokes youth, femininity, and elegance all in a glance.
