About TJC

TJC is associated with the jewellery industry worldwide – we are affiliated with The British Jewellers Association (BJA), the Thai Gem & Jewellery Traders Association, The Jewellers Board of Trade and the International Coloured Gemstone Association. TJC is also one of only 8 site holders to the "Tanzanite One" mine in Africa, meaning we can offer these rare and highly sought-after precious gems at prices which competitors would find virtually impossible to rival.
