Purchased in-store at Kanda. This is the most expensive one, with ceramic processing. Stone: Cubic Size: 42cm (no adjuster) Inspired by a crescent moon floating in the night sky. The cubic zirconia inside sways, shining on the chest like sparkling stars. The machine-cut cubic zirconia shines as brilliantly as a diamond. Each piece is carefully crafted by skilled jewelry artisans. The earring posts use K10, so those with allergies can use them with peace of mind.
