Just back from the Faberge exhibition at the V&A museum in London, if you're in London & can get tickets it's a must see. They say it's sold out, but they're working to make more tickets available (whatever that means). Sadly no photography allowed but the catologue is now heavily discounted. Try for 'returns' if you can.
This time I booked tickets about two months ago, normally I leave it until the last minute & then lose out .
