His personal collection of 6000 minerals came together after travelling to Australia, Germany, China, the USA and England.
Mr Blakemore said he loved coming to the shows because he was friends with the other dealers and showing and selling the customers his beautiful gems and minerals was satisfying.
Georgia Atkinson, 21, said the only downfall of collecting gems and crystals was she always wished she had more money to buy more.
"I love coming to shows to look at the beautiful things. My favourite is purple amethyst."
Punters at the show learnt about geology and got to see world class crystals, gems and fossils.
