Following up on the previous post, this is the matching bracelet to the necklace, also worn at the Sun Military Awards in 2011.
Here is the closeup:
Echoing the design of the necklace, the bracelet is made of white gold and features two lines of small round diamonds encircling the wrist. In between the two lines are smaller lines of diamonds running perpendicular to them, creating “cells” for the rubies and diamonds to be set inside them. Small circles studded with diamonds and flower-shaped rubies with diamond centers alternate between each cell, creating a diamond circle/ruby flower/diamond circle motif. I believe this has a fluid link (fold over clasp).
This is believed to be a part of a set Kate received when she married William.
