British designer Kiki McDonough is a favourite of Kate Middleton, the Duchess of Cambridge. She has a pair of her topaz and diamond stud earrings and has been photographed several times, most recently at a function for the London 2012 Olympics) wearing these hoop earrings.
I’m a fan of the blog http://whatkatewore.com/, as they break down Kate’s various looks and, as it turns out, many come from affordable chain stores and designers. I really like that Kate recycles what she wears because it shows a sense of confidence and style to pair things with different outfits and always look polished. I’m sure if I had access to some of the jewels she can borrow, it would be tempting to go overboard, even at occasions which may warrant more. But she appears to stay true to the style she had before marrying William.
These earrings are not on McDonough’s web site, but many other blue topaz and diamond pieces are, and the prices are reasonable.

“But she appears to stay true to the style she had before marrying William.”
This is why I like her. 🙂
One day she is going to have to deal with wearing a lot showier bling, though. Good thing there is a ton from which to choose! And even Diana modernized some of the older pieces – the emerald choker she used as a headband, for instance.
