Amazing NEW Boulder Opal

In this video from Pulitzer Opal, Sheila introduces two new types of opal, with contributions from Riley Gun of 53Frogs and Zhivago Castro Romalho of Opalas do Brasil. Sheila starts by discussing chunks of Coober Pedy opal from Australia, noting their unique patterns and moderate cost. An arrowhead is made from her opal by her assistant!

She then examines a 390-carat boulder opal from Brazil, pointing out its dark gray base rock and signs of rust. It is considered likely that the base rock for Brazilian Boulder opal is Iron Ore, likely Magnatite and/or Hematite, because of the gray-black color. Sheila decides to cut the boulder opal into a cabochon, highlighting the challenges and steps involved in the process.

Next, Sheila tackles the interesting topic of Mexican "Leopard Opal," detailing its formation in vesicular basalt and its historical use by the Aztecs and Mayans. The video concludes with Sheila showcasing and naming various opal pieces, discussing their characteristics and potential new owners (this sounds like a giveaway to me).

Throughout the video, Sheila blends humor and gemological details, making the topic engaging and informative. -- ChatGPT
