These are the modern incarnation of a design that I’ve been evolving over 30 years. There’s short video about that process on my blog.
They measure 35mm from top to bottom and the semicircular swinging sections are 15mm across.
The beads are all 9ct gold and there are gold caps to the silver sections as well.
All in all, a very classy pair of earrings that would be suitable for special occasions or every day wear.
