Another item that will attract the attention of bidders is a jadeite bead necklace (pictured above) with an estimate of $3.2 million - $4.5 million. “Evenly and strongly saturated, each of the jadeite beads featured in this necklace exhibits the optimal combination of color, translucency and texture,” Christie’s says. “The beads display a vivid emerald green color with a desirable tone that is neither too dark nor light. Their fine texture and excellent glass-like translucency only bolsters the rareness of such high-quality material, resulting in one of the most anticipated jewels offered at auction this year.”
