If you are ever in any doubt about how magical planet earth is, a quick trip to see the mineral collection at London’s amazing Natural History Museum should reassure you. 14,000 specimens are on display, taken from everywhere from the moon to Mexico via South Wales (an area with a surprisingly large array of colourful rocks).

I am something of a crystal geek, so I took a trip to visit the rocks last Friday and this is what I saw - I’m hoping that there are other geeks out there who will appreciate my efforts. These specimens are picked purely on their unusual colours and forms - I am no geologist…although I wish I was.
