The telltale sign of a Wendy Yue cocktail ring? The fabulously rendered, almost-overwhelming presence of flora or fauna. Yue’s pieces always seem on the verge of coming to life: Green garnet stems curl down from a cherry blossom; a pink sapphire scorpion crawls across a coral rose; blooms, branches, and vines tangle together in a gem-filled garden. In this frog ring, which retails for $12,500, Yue again features a creature. The pearl, however, is new territory for the Hong Kong–based designer, who’s perhaps best known for her creative use of carved stones such as coral, jade, and agate.
