NoteA fine jadeite bead necklace has always been considered one of the most classic and rarest connoisseur jewellery items. To assemble a considerable number of jadeite beads, a huge jadeite boulder is required to provide enough quality beads for selection. On average, two-third of theses beads are rejected in the process, so only beads of the best matching colour and translucency are chosen. This very necklace is a fine example resulting from such a highly selective procedure. It is composed of 108 jadeite beads of superb quality, carefully selected from a pool of 500 beads originating from a boulder that weighed almost 5 kilograms. Each jadeite bead is scrupulously hand-picked to ensure well-matched colour, texture and translucency.
