This part is quite complex. In some cultures receiving gold and jewelry is a good "presage" when you're a woman but less when you are a man (esp in Islamic interpretations). Wearing or receiving jewelry which belong to another person indicates that that you will benefit from that person in some ways. As for the necklace with precious stones, it indicates faith knowledge, a husband if you're a woman. Wallahu A'lam .
Anyway, note that most of what I said is from an spiritual and Islamic point of view (nothing Freudian ahaah !). Thank you cuz it kinda put me in a suit I hadn't worn in a long time. Now I feel like I'm in one thousand and one nights again !
