Widely believed to be part of a suite of jewels gifted to her when she got married, Kate debuted this stunning bracelet during the 2014 NYC trip. She paired it with her ink-blue Jenny Packham gown at the St. Andrews gala.
The bracelet is made of two rows of diamonds (white and yellow) strapped to a center stone consisting of a large emerald set in a square-cut diamond setting. I am assuming this has a foldover clasp. This could be set in either white gold or platinum.
Here it is on Kate.
I believe this is a wedding gift. It has a matching pair of earrings and it’s a very extravagant piece (Kate’s taste in jewelry is not extravagant). This has not been identified for a designer yet, but I have a feeling this could be from a Middle Eastern royal. It reminds me a lot of what Princess Diana received when she got married in 1981.
