Bracelet and Ring
When Posthumus and Imogen say goodbye to one another, they express their love by giving each other tokens: Imogen gives Posthumus a ring while Posthumus gives Imogen a bracelet. These tokens symbolize the love and trust that exists between them, and tokens of love were a common occurrence in Shakespeare's plays (they also, notably, tended to serve as a catalyst of misunderstandings among characters that often lead to tragedy). When Iachimo takes both the ring and the bracelet after "winning" the wager, it is symbolic of how he has intruded on and destroyed the love between Imogen and Posthumus – so much so that Posthumus orders Imogen to be killed.
Imogen's Mole
In order to win the wager against Posthumus, Iachimo must provide some type of proof that he was able to seduce Imogen. Iachimo sneaks into Imogen's bedchamber while she is asleep, and memorizes the details of the room in order to convey the message to Posthumus. One of these details is a mole on Imogen's breast (which Iachimo sees after uncovering her). The mole symbolizes both Imogen's privacy (violated by Iachimo) and her virginity, as anyone who has seen such an intimate part of her body would, in the eyes of the men in the play, have certainly slept with her.
BIrds
Birds are an important motif in the play, as they appear in a number of instances to symbolize certain characters' personalities. Imogen is, for example, compared to a phoenix: virtuous and benevolent, with the added ability to rise from its own ashes (which she does by the end of the play). Imogen also compares Posthumus to an eagle and Cloten to a puttock, suggesting that Posthumus is strong and noble while Cloten is a self-interested "scavenger." Finally, the prophecy at the end of the play is rife with bird imagery, as the oracle compares Rome to an eagle (strong, powerful, noble) and Britain to the sun, ultimately suggesting that Britain will one day overtake Rome in terms of power and longevity.
Apparel
Clothing is a central motif of the play, as its use addresses one of the play's major themes related to appearances. Through characters' clothes, the play raises the question of whether outward appearance reflects one's inner qualities. Certainly, Posthumus and Imogen believe that appearances are unimportant, while Cloten places immense value on how one dresses. When Imogen insults Cloten by saying Posthumus's "meanest" garments are more valuable to her than Cloten himself, Cloten responds by dressing in Posthumus's clothes – completely missing the argument that Imogen was trying to make.
The Sun
The sun symbolizes Britain. Throughout the play, characters comment both literally and figuratively on the brightness of Britain, comparing it frequently to the sun and remarking that there is no better place. At the end of the play, the oracle, too, suggests that Rome will eventually "dim" in the presence of the sun, hinting at the British Empire of which Shakespeare and his contemporaries were a part.
