Yet another reason I need to get back over to the UK!
From The Telegraph:
Prepare to be dazzled – after years in storage the V&A’s jawdropping collection of jewellery from the past 3,000 years is about to go on permanent display.
…
On 24 May the William and Judith Bollinger jewellery gallery will open at the V&A, displaying 3,500 items from the museum’s collection, which is one of the finest and most comprehensive in the world and tells the story of European jewellery over the past 3,000 years.

Chadour-Sampson pulls out another drawer and places in the palm of my hand a small locket, the Armada or Heneage jewel made about 1595, a gift from Elizabeth I to her vice-chamberlain, the poet and secret-service agent Sir Thomas Heneage. The locket depicts a profile portrait in gold of the queen up to her neck in a giant gold ruff, her head weighed down by wig and pearls, encircled by diamonds and Burmese rubies. Turn it over and there is a gold and enamelled portrait of an ark, representing the English church, riding through stormy seas, a cloud above raining down lightning on the frail vessel. Open it up and there’s a portrait of a much younger, more girlish Elizabeth, the real woman behind the symbol, or how she wanted to be seen – a wistful love token sent by an old woman.

And here are some images of the Elizabethan jewel described in the article (from the V&A website…. you can see larger images if you go to their image collection page and search for “Armada jewel”):
