Accessories were the Apple Watch Series 2 (42mm Rose Gold Tone Aluminum with Pink Sand Sports Band, Her Majesty has already got one with the silver band.) For shoes Her Majesty had on the Casadei Barbella pumps in Pink from their Casadei Chain Mini-Collection (Thanks to fellow royal fashion blogger and friend on Twitter Heaven for informing me). Update there seem to be an exact similar design to the Casadei pumps with that of the Christian Dior Wired Pointed Toe Pumps
 She also had on the H-Stern Celtic Dunes Ring in 18K textured yellow gold, Ferrari Firenze “Spettinato” Yellow Gold & Diamonds Handmade Earrings(I.D by the Italian House on Instagram)

I think Queen Rania might have been wearing Casadei shoes yesterday and on the cover of Sunday Times magazine earlier this year pic.twitter.com/FJcMw03ZeS

Yesterday's event was not the first time she wore Emilia Wickstead. For Her brother's wedding in May 18th, Her Majesty also wore Emilia Wickstead dress. This wore the Emilia Wickstead The Thais Pleated Shift Lace Dress (Thanks to Passion_4_fashion) with  Apple Watch "Series 2" silver aluminum case in 42mm

The designer is a staple in other royal ladies wardrobes. You may have seen her designs a lot of times on HRH Catherine, Duchess of Cambridge and HRH Sophie Countess of Wessex
