This petite, delicate necklace lights up with diamonds and a centre set emerald. By Japan’s Kataoka, specs are “emerald 0.25 ct., diamond (total) 0.10 ct., chain: adjustable, 45 cm (18″) maximum length; pictured: 18k beige gold chain.” I’m not quite sure what beige gold is but it looks like it’s lighter than yellow gold but not as pale as white gold.

This sells for USD$2,980.
