This 18k gold Le Marche de Merveilles ring by Gucci is a timeless snake/serpent design, set with a diamond. I’m personally a fan of Victorian snake pieces and something with a little less polish and shine to it.
Gucci describes it this way: Our pink gold serpent ring with a star cut diamond on the head and brilliant cut diamonds for the eyes.
They go on to note it has hand-set diamonds and engraved texture detail; no price is given but it appears it can be purchased online. I am guessing it’s meant to be worn on a non-ring finger as the smallest size is a 10 and it’s showing in the women’s category.
