Amid all the royal engagement excitement, the Duchess of Cambridge stepped out in London on Tuesday morning for an engagement of her own at the Foundling Museum.

Kate reached into her jewelry box for a favorite pair of earrings for the visit: her sapphire and diamond cluster drop earrings. You can learn more about this pair over here.

She also wore her usual trio of rings: her engagement ring, her wedding ring, and her slim diamond eternity band.

Here’s a look at Kate’s entire ensemble for the day. Unusually, she made a point to speak with members of the press about Harry and Meghan’s engagement, expressing her excitement over having a new sister-in-law.

The Duke and Duchess of Cambridge stepped out in London on Friday night to attend the annual Royal Variety Performance, and Kate chose head-to-toe sparkle for the event.

Her earrings were almost impossible to see through her hair in most images from the occasion, but this view shows that they’re the diamond chandelier earrings on loan to her from the Queen. She’s been wearing these since 2011; more on them over here!

Kate’s only other accessories were her usual trio of rings: her engagement ring, her wedding ring, and her eternity band.

With a dress like this spangled Jenny Packham number, Kate was wise to keep the accessories to a minimum!

The Queen and the Duke of Edinburgh threw a party for their platinum anniversary at Windsor Castle this evening, and we got a glimpse of a new piece of borrowed jewelry on the Duchess of Cambridge.

During her arrival with William and Harry, photographers snapped Kate wearing pearls. She donned her late mother-in-law’s Collingwood Pearl Earrings with an exciting new borrowed jewel: the Queen’s Four-Row Pearl Choker.

The choker has been in the Queen’s collection for decades; above, she wears it in 1983 in Bangladesh with the Girls of Great Britain and Ireland Tiara. (You can read my previous post about the necklace over here!)

Diana wears the pearl choker in 1982

HM also previously lent the necklace to Princess Diana. Above, Diana wears it at Hampton Court Palace during the Dutch state visit in 1982, pairing it with Queen Mary’s Lover’s Knot Tiara and the large sapphire brooch that she would later use as the clasp of her own pearl choker necklace.
