Additional pictures of the engagement. Aimee and Anita are flashing those rings to the cameras, but not a close enough look at them. In the third picture of Floris and Aimee the ring does look very shiny though. I'm sure the van Vollenhoven boys didn't skimp on their girlfriend's engagement rings!
From the Benelux Royals MB:
Anita and Pieter-Christiaan met each other in London. Being both employed at a bank they soon became a 'bankstel' according to PC. A 'bankstel' is Dutch for lounge suite (sofa plus chairs). But a 'bank' can also be Dutch for bank and a 'stel' is Dutch for a couple. Pieter-Christiaan proposed to Anita on the roof of Het Loo Palace.
Floris met Aimée in Leyden. First time he saw her he thought that she was IT. Love at first sight? Dad Pieter said that the family was 'sold out' now...
