The Megalodon Shark was the biggest predatory shark to ever live. Reaching lengths of 70 feet or more, these monstrous sharks ruled the oceans for more than 10 million years. They were so large they fed on whales. Some believe the Megalodon shark could still live in the depths of the oceans, but most scientists agree that Megalodon went extinct about a million years ago. Why is a mystery, but some possible explanations are climate change, changes in its primary food source, and competition for food from rivals such as killer whales and the modern great white shark.

Astro West is owned and run by Marc Tanjeloff a 3rd Generation Mineral dealer. Once Vice President of  Astro Gallery which is still family owned and operated since its founding in 1963. Its founder, Julio Tanjeloff, was a successful businessman in Buenos Aires, Argentina. By 1961, Julio had emigrated to New York City with his family and having become infatuated by minerals. In this vision, he opened the spectacular Astro  Minerals in 1963. The operation quickly grew into a stunningly lavish 16,000 square foot establishment that drew mineral collectors, gem collectors, celebrities, politicians, interior decorators, architects, and designers. In 1970, he began publishing Mineral Digest to promote minerals and his business, which still ranks as the most extravagant mineral periodical of all time. This new venture is a tribute to Marc's Grandfather with a more in depth concentration of Mineral collecting.

 Blue Zoisiste - Tanjeloffite

Blue Zoisiste - Tanjeloffite

Around 1967, gem grade blue zoisiste was discovered in Tanzania, and Julio was the first person to bring the crystal into the United States. Calling his new find Tanjeloffite, Julio proudly displayed his eponymous rock for sale throughout his stores. In a famous dispute with retailer Tiffany & Company, rather than use the name Tanjeloffite for the stone, Tiffany & Company marketed the rock under the moniker Tanzanite. The latter name stuck. It wasn’t until 2008, when the mineralogical record was amended to include the lesser known name, Tanjeloffite, as an official name of the stone, that Julio Tanjeloff was properly honored.
