Thought they were real until one peeled!

Thought these were real (clasp marked 14k) until today when one peeled (the much lighter one)… can someone please tell me what these are? Glass? Thank you in advance for any help

Well that's disappointing!
Most imitation pearls that feel heavy like real pearls are glass. Very cheap lightweight ones are plastic.
The clasp may not be real gold either.
