There are dozens of famous diamonds and other gemstones at the Smithsonian National Museum of Natural History in Washington DC, including the earrings of French queen Marie Antoinette, but the most famous bauble is the blue Hope Diamond, weighing just over 45 carats.

All other crown jewels – even those of the Tower of London – fade in comparison with the eye-boggling Treasury of National Jewels lodged in the Central Bank of Iran in Tehran. The kitsch array of tiaras, crowns and necklaces was amassed over centuries by Safavid kings and Persian shahs. There are literally tonnes of plump yellow diamonds, rubies and emeralds. Highlights are the Peacock Throne and a bejewelled world globe. See cbi.ir

There are plenty of extraordinary art museums, but given the craze and auction prices for Impressionists, you could hardly find a better collection than that in the Musee d'Orsay in Paris. It specialises in art from 1848 to 1914 and has iconic paintings from the likes of Monet, Renoir, Degas, Cezanne, Gauguin and van Gogh. The magnificent belle epoque museum building, a former train station, is also marvellous. See musee-orsay.fr

Europe abounds in over-the-top palaces, but no city has as many as St Petersburg, and few are as opulent. The famous Hermitage art collection is almost overshadowed by the splendour of the Winter Palace that houses it; Rasputin was assassinated in the lavish Yusupov Palace; Menshikov Palace showcases 18th-century Russian society. Outside the city, Catherine Palace and Peterhof are weighed down in gold and surrounded by impressive gardens. See visit-petersburg.ru
