10K white gold. 1/2 carat total weight of diamonds, each earring features a single shimmering diamond artfully set to enhance size in the middle. Each stud earring shine with two round diamonds per side (4 sides per stud earring). These post earrings secure comfortably with friction backs. These have been worn and need a professional clean. I have cleaned them with soap and water, but that’s it. Comes with original box and price tag.
