This bangle was her engagement present from QMII. QMII used to wear this bangle too.
I don't think so. The drop length of the earrings don't correspond to the length of Princess Mary's earrings.It looks like that mary wearing new earrings (from Day 4, concert) from jewlscph: http://uk.jewlscph.com/products/3-earring/....specials.p-03/
But they are not really the same ?!?
