The Shape of Matter: Through An Artist's Eye
Jewelry by Paula Crevoshay

October 21, 2021 - April 20, 2022

The works of internationally renowned jewelry designer Paula Crevoshay have captivated hearts for decades, from jewelry connoisseurs to celebrities and amateur gem buffs. On display are approximately 70 of her nature-inspired pieces, including a world museum debut, Sea Star. Paired with loose gems and minerals, all are displayed within their respective crystal systems. The exhibition illuminates the link between minerals, gems and jewelry while providing a path to learn more about intricate crystal structures. Come explore the art of the jewel and the science of crystal formation!


Dragon's Lair Gold

Take a rare glimpse at approximately 921 troy ounces – or 63 pounds – of gold! It is one of the largest and most remarkable finds to come out of Western Australia.

The gold was initially encased by a large boulder of quartz, but through the painstaking work of expert technicians, the Dragon’s Lair emerged. Taking place over hundreds of hours, the process involved several cycles of incising, acid etching, and iron removal.

Come see it for yourself!

Ausrox Gold

Plus, don't miss Ausrox Gold! In 2010, three miners armed with a metal detector and a small tractor discovered Ausrox out in the Eastern Goldfields of Australia. It weighs approximately 748 troy ounces – or 51.3 pounds – of gold!

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

Unearthed 10 years ago by a miner in Namibia, the enormous and intensely beautiful specimen had an interesting beginning. When the miner realized his discovery was incredibly rare, rather than sell it right away, he toted it around in the trunk of his car. As word spread, two collectors spent days searching for this infamous mineral-toting Mercedes. Once they tracked down the miner, the car, and the mineral, they made a deal to acquire the piece, shipping it back to the U.S. protected by 400 diapers!

Compare different minerals

Halite and calcite may look exactly the same, but taste completely different. Pyrite and gold are easy to confuse, but when you look closely pyrite has cubes all over it! Look closely to find the unique differences in minerals that seem to masquerade as something else.

Understand the origin of minerals

Minerals are like a recipe that comprises different elements found right here on Earth. Each mineral isn't just one element — it's a special recipe of elements that help form colors, shapes, and hardnesses.
