This is a whimsical fun seed pearl, Japanese akoya saltwater cultured pearl and 18K yellow gold bicycle tie tac.

The pearls range from 1-5.00mm.They have fantastic luster with rosy overtones.

The bicycle and stem is made of solid 18K yellow gold and is stamped "K18" for 18K. It is bright yellow gold. The front wheel also spins freely! Stamped "Taihei" on the front for a bicycle seat manufacturer in Japan. The back of the tie tac and button loop is not gold as is common. Total length is just under 1 inch. 

All pearls are truly vintage and have only been lightly cleaned.
