While at a ball held at the Southern Cross Hotel in Melbourne (1985), Princess Diana was wearing what looks to be an emerald cabochon and diamond ring instead of her engagement ring. The two stones are not aligned but are at an angle to one another, very similar to a style of a bypass ring. She also wore this ring on 11 November 1993 while attending a state banquet hosted by The Yang Di-pertuan Agong of Malaysia at The Dorchester Hotel in London.[1][page needed][2][page needed][3]
