Tune in and take advantage of the Gem Hunter’s unrivalled knowledge and expertise.<br /><br />After scouring the four corners of the globe in search of the finest, rarest and most exotic gemstones on the planet, the Gem Hunter returns to London with exquisite gemstone jewellery not to be missed. Key highlights are the launch of a special selection of Paraíba Tourmaline at 8pm Friday and Pirineu Tourmaline 8pm Saturday.<br /><br />Unearthed just under 20 years ago, Paraíba Tourmaline is the pop sensation of the Tourmaline family and a true gemstone superstar. In the relatively short time since its discovery it has not only redefined the perception and appeal of Tourmaline, but also gemmological beauty. While the deposit in the Mavuco (pronounced: Ma-Voo-Co) area of Mozambique initially helped fulfil the demand for this hugely popular gemstone, there is currently nothing commercially significant being pulled from the ground. It’s virtually impossible to purchase any rough Paraíba Tourmaline crystals on the open market. Faceted by some of Brazil’s best lapidaries, every Paraíba Tourmaline in this collection has been personally selected by Tony and comes with an ownership booklet guaranteeing its authenticity. A modified version of this booklet is available online as an e-zine at <a href="http://www.rocksandco.com">www.rocksandco.com</a>, simply click on the banner above.<br /><br />Rare and beautiful, Pirineu Tourmaline is the best Blue Green Tourmaline Tony has ever seen. Named for Brazil’s Pirineu Mine (pronounced: Pi-Ri-New) located near Taquaral in the state of Minas Gerais (Portuguese for ‘general mines’), Pirineu Tourmaline is prized for its stunning bluish-green ‘peacock’ hues. The Pirineu Mine is Brazil’s most famous source for quality Blue Green Tourmaline, but only has a very limited and sporadic output. Understandably, this rare and unusual Tourmaline colour is striking, beautiful and highly collectible. There will be more surprises so make sure you’re watching the Gem Hunter as he gives you accurate and fascinating insights into the background of each gemstone.<br /><br />With over 12 years international experience sourcing and dealing in gemstones, Brazilian Tony Diniz has many achievements under his belt. He was one of the first people involved with Mozambique Paraíba Tourmaline; he found significant quantities of some of the world’s finest Kunzite while on adventures in Afghanistan’s Kunar Valley; and was the first to present Blue Fire Opal to the world, right here on Rocks & Co.<br /><br />Don’t miss Tony Diniz this weekend on Sky channel 642 (8am - 2am) and Freeview channel 49 (8am - 10pm), where he’ll give you the story behind the gem.
