Vintage Clip On Earrings Unusual Star? Snowflake?

These earrings measure about 7/8". Really unusual, not sure of material, is a pearlescent cream tone. Some marks, signs of wear and glue reside to rear. Small tarnish spot to rear.

Preowned vintage earrings, sold as shown - I am unsure of material type(s) because of this. Pictures show different angles for you to review - while I attempt to note any defects, some tarnish/signs of wear may be visible that are not otherwise stated.

Earrings are tested and photographed on a thin/smooth earring stand (not included) to show that the clips are in working order.

If you have any questions please feel free to drop me a message.
