They measure about 36mm long, please see the photos. I wore them on a few special occasions including a cruise and a wedding, but with a baby arriving in a few weeks, I know I will not get to wear them much anymore. They are in overall excellent condition and come with a pouch. Marked DY 925 on both the earrings and the backings (although that is hard to see on the backs).
