Although citrine may not be the most luxurious of gemstones, the David Yurman Necklace still has refined style. Hanging from an 18-karat yellow gold box chain necklace, the elongated citrine and pavé diamonds shine brightly, making it quite the showstopper. At $3,900, it may feel a bit extravagant to wear casually, but if I wasn`t so nervous about wearing such a luxurious and expensive necklace, I would wear this as much as possible. Stone measurements: 30x15mm.
