THE OPAL MINING CAPITAL OF THE WORLD UP CLOSE AND PERSONAL AS TOLD BY ONE OF THE ORIGINAL MINERS "It took 30,000,000 years for this outstanding opal to show it’s beauty to the world. I think the wait was worth it," says Czech WW2 refugee and Australian immigrant George Cettl, who forsook the safe suburbia of his adopted homeland to make his claim in the wild, outback frontier opal mining town of Coober Pedy. A beacon to a generation to European "boat people", the town and its surroundings soon became the world's premier source for the precious stone opal - responsible for most of the opal jewelry circulating internationally today. But what is this mysterious opal? What legends circulate around it? How was it mined and the jewelry made? Now, from one who did it, who lived it as actual daily life experience comes this authentic memoir dedicated to the unusual rainbow stone.

For most of the past 300 million years, the world’s continents were interlinked as the supercontinents Pangaea and then Gondwana. Around 50 million years ago, Australia tore itself free from Antarctica to become the huge, splendidly isolated island it is today. Over time, its creatures began to evolve in ways not seen anywhere else on Earth, with tree-climbing crocodiles, gigantic venomous lizards, walking omnivorous bats and flesh-eating kangaroos roaming the continent. Prehistoric Australasia: Visions of Evolution and Extinction presents some of the most extraordinary creatures the world has ever seen – all unique to Australia, New Guinea, New Zealand and their surrounding islands. Over 100 meticulously painted panoramas by palaeoartist Peter Schouten are accompanied by descriptions of the unique environments and features of these animals, written by four of Australia’s foremost palaeontologists. This book explores the nature and timing of extinction events in the Southern Hemisphere, considers whether some of these losses might be able to be reversed, and how we can use the fossil record to help save today’s critically endangered species. Through stunning artwork and fascinating text, Prehistoric Australasia brings this globally unique transformation over time to glorious, colourful life.

Elie Wiesel called the genocide of the Armenians during the First World War ‘the Holocaust before the Holocaust’. Around one and a half million Armenians - men, women and children – were slaughtered at the time of the First World War. This book outlines some of the historical facts and consequences of the massacres but sees it as its main objective to present the Armenians to the foreign reader, their history but also their lives and achievements in the present that finds most Armenians dispersed throughout the world. 3000 years after their appearance in history, 1700 years after adopting Christianity and almost 90 years after the greatest catastrophe in their history, these 50 ‘biographical sketches of intellectuals, artists, journalists, and others...produce a complicated kaleidoscope of a divided but lively people that is trying once again, to rediscover its ethnic coherence. Armenian civilization does not consist solely of stories about a far-off past, but also of traditions and a national conscience suggestive of a future that will transcend the present.’ [from the Preface]

Each gem deposit-whether of primary origin in the parent rocks; or secondary as alluvial placers in valley floors, river gravels, or the sand of oceanic shelves presents an eloquent chronicle of the Earth's life story. It reveals to the expert the prodigious processes which formed the present crust of our planet, of which this volume discloses a small but exciting detail. The materials of the Earth's crust are the rocks. In this book, the author expounds on how they were formed, why they altered, why they became the cradles of precious gemstones, how they are categorized, and how they are now exploited by man. What initiates the growth of gemstones? How do they crystallize? Why do gemstones of the same species, originating from different sources, vary? What causes the occurrence of varieties? Why do diamonds, unlike other precious stones, occur not near the Earth's surface in its crust, but deep down beneath it in the upper mantle? These are only a few of the entrancing subjects discussed in this enlightening volume. The reader learns that the Earth is surprisingly alive and altering constantly-sometimes through slow and equable changes and at times by violent and tremendous cataclysms, events from which gemstones issue.

Lightning Ridge gems are opal miners and the women who followed them into the Australian outback where they created a spectacular mosaic of old and new world cultures. Thirty people who came to Australia from twenty four countries tell their heroic and triumphant stories of how they came to be here and how they see life from their perspective.
