The "La D de Dior" embodies the spirit of Dior jewelry. This collection is a stunning fusion of bold creativity, combinations of different materials and colors, and Swiss watchmaking expertise. 19mm diameter case: Steel, yellow gold, mother-of-pearl, and diamonds. I purchased this in the past, but I'm selling it because I haven't had the opportunity to wear it since I replaced it with a new one and have kept it stored away.
