These sort of green pearls are known as 'Yemengzhu,' and they've long played a role in Chinese legends. Some people even believe that touching one will "bring great fortunate and prosperity."

  The stone, formed mostly of a fluorite mineral, glows green in the dark and is prized more highly than diamonds in China.

   The first ever modern Yemengzhu, however, was discovered in China only 20 years ago. The unique gem is indigenous to China, and cannot be found anywhere else in the world.

   A collection of more than 200 pieces of natural artwork and natural gems were also displayed and open to the public for free.

   The luminous stones, sometimes known as a Chintamani, are a wish-fulfilling jewel within the Buddhist religion.
   Fluorite is well known for the amazing colours it can give out, so much so that it has been given the nickname of 'the most colourful mineral in the world'.
   Its unique properties mean that the characteristic of fluorescence, when a material emits light, is named after fluorite itself.

According to Guinness World Records the world's largest cut diamond is an unnamed Fancy Black, containing small red diamond crystals. It weighs 555.55 carats and was polished into 55 facets over several years .

 Guinness World Records also recognized the largest carved sapphire, which is a multi-coloured (blue, gold, grey) polished rock that weighs 80,500 carats (16.1 kg, 35.49 lb).

The Guinness World record for the Largest Gold Coin weighs 100 kg (220 lb 7 oz), measures 50 cm (19.6 in) in diameter, 3 cm (1.1 in) in thickness and is made from bullion with a purity of 99.999 per cent; it was introduced by the Royal Canadian Mint with a face value of CAN$1 million (US$900,375).
