To celebrate Hatton Garden Jewellery Week (hattongardenjewelleryweek.com), from June 7-13, London's oldest jewellery quarter is staging a host of jewellery-inspired events and activities.

One of the highlights is a street festival on Saturday June 12, from 11am to 6pm. You'll be able to watch jewellery being made, and produce your own in flash workshops. There'll be the chance to enter competitions with prizes worth up to £3,000, plus lots of other offers - not to mention the chance to shop for a sparkler.

While you're there, head to Nicholas James (www.nicholasjames.com) to check out the world's most precious bridal gown. The dazzling dress is created from a fabric containing microscopic threads of platinum. A snip at £100,000!
