Look closely – amongst all the mesmerizing purple are white calcite crystals. The Grape Jelly Amethyst Geode was the very first exhibit installed at the Museum – the gallery was quite literally built around it!

The Eyes of Africa and its backstory that includes diapers and a white Mercedes

Discovered by Herold Gariseb in the Erongo Region of Namibia, this two foot tall specimen of quartz (white) and fluorite (green) had an interesting beginning. When the miner realized his discovery was incredibly rare, rather than sell it right away, he drove it around in the trunk of his white Mercedes Benz. As word spread, two collectors spent days searching for the infamous miner and his car. Once found, a deal was made to acquire the piece and ship it back to the U.S. wrapped in 400 baby diapers placed in a plastic barrel inside a steel drum!

A colorful Ammonite donated to the Museum by the Lavinsky Family

Ammonites are a type of shelled cephalopod that went extinct about 66 million years ago. Although ammonite fossils are discovered all over the world, colorful specimens such as this one can only been found on the eastern slopes of the North American Rocky Mountains, in particular the Bearpaw Formation in Alberta, Canada. Although the play-of-color may look similar to opal, it is actually more closely related to pearl! An iridescent layer of nacre, made up of the mineral aragonite, coats the top of the fossil. In the gem trade this is known as ammolite, and is sometimes cut off the fossil and set in jewelry.  This specimen measures almost 2 feet in diameter!

Two exquisite and rare gold pieces originally unearthed in Australia with a combined weight of more than 110 pounds

The larger of the two pieces – dubbed the Dragon’s Lair (right) – tips the scales at 63 pounds making it one of the largest and most remarkable specimens to come out of the richest gold finds in Western Australia.  Its smaller lustrous companion – known as the Ausrox Nugget – weighs in at a whopping 51.29 pounds and is about the size of a basketball.  Three miners armed with a metal detector and small tractor discovered Ausrox in the Eastern Goldfields of Australia.
