History: Today's Minerals27588newicon

In 1992, Marc Wilson took over the management of Hillman Hall. Under Wilson’s stewardship and with the continued support of The Hillman Foundation, the museum’s century-old mineral collection has blossomed. New exhibits have been developed and specimens upgraded to include an abundance of world-class minerals and gems.

Among the hall’s improvements since Wilson’s arrival is the complete makeover of the Pennsylvania Minerals exhibit. Obtaining the best available Pennsylvania specimens has long been a goal of the Minerals section and this exhibit represents the roots of the museum's mineral collection. The exhibit currently displays specimens from the Bryon Brookmyer collection, on loan to the museum.

Also included are two types of a common amber substitute, copal. Amber and copal are shown in their rough forms and as freeform polished specimens and jewelry. Insects embedded in amber demonstrate how life forms become fossilized in the resin.

The developing nature of the hall was evident in late October 1996, when Wilson unveiled a new exhibit of Pseudomorphism in Minerals. One example is the museum’s first world-class mineral, accessioned in 1897—pseudomorph of hemimorphite after calcite, now on display in Masterpiece Gallery. Over the past century, this pseudomorph has not been surpassed, and it remains perhaps the most significant specimen in the collection.

Another addition to Hillman Hall occurred in 1997 with the opening of the Minerals of the Former Soviet Union exhibit—some 30 spectacular minerals from the recently acquired collection of 250 high-quality specimens. Minerals from the former Soviet Union began entering western collections as a result of the fall of Communism.

The year 2000 brought two renovations to Hillman Hall. The Fluorescence and Phosphorescence exhibit received spectacular new specimens and presentation to show how minerals “glow” under ultraviolet light. The Twinning in Minerals exhibit uses beautiful minerals to show how crystals can become doubled.

The year 2002 saw the unveiling of the Quartz exhibit. Because quartz, the most common mineral on Earth, can be classified as a silicate or an oxide, it was decided to take all quartz specimens out of the Systematic Collection and create a standalone exhibit. This display features specimens of quartz with diverse colors, crystal habits, and inclusions from localities around the world.

A proposal was made in May 2004 to expand and improve Hillman Hall, and in 2006 the renovations and expansion project began. Many changes were made to the hall including both additions of and removal of exhibits. Most of the jewelry and gemstones were taken off exhibit for use in their new home of Wertz Gallery: Gems & Jewelry. This new addition to Hillman Hall opened in September 2007 and includes a permanent Birthstone exhibit as well as changing exhibits of gemstone, jewelry, and gem crystals.

When Hillman Hall reopened in June 2007, visitors could enjoy improved exhibits on Lithology (the science of rocks), an expanded Masterpiece Gallery, and new exhibits on locality suites to complement the already existing exhibit on the former Soviet Union. These suites feature minerals from England, Romania, India, and Bulgaria. A beautiful new entrance greets visitors with stunning specimens as they enter and exit the hall. Also displayed near the entrance are Mineral Slices, backlit slabs of beautifully colored minerals and crystals. Look for many of your favorite exhibits which still grace the hall.


The year 2007 also saw the addition of nearly 5,000 Pennsylvania minerals to the collection that were formerly in the Academy of Natural Sciences in Philadelphia. This important acquisition enhanced the historical and scientific value of the museum's Pennsylvania holdings. In 2014 the museum acquired the Pennsylvania collection of over 2,700 specimens from legendary field-collector Bryon Brookmyer. Carnegie Museum of Natural History can now boast of having the most comprehensive Pennsylvania mineral collection in the world.


Still on the drawing board are plans for a computer station in the hall to give visitors access to complete information on any specimen on exhibit. Under Marc Wilson’s expert guidance, Hillman Hall continues to develop to meet the interests and needs of its visitors. Your support in the form of donations, whether monetary or specimens, is always appreciated and helpful in our continuing effort to keep Hillman Hall of Minerals and Gems one of the finest mineral exhibits in existence.

Carnegie Gem and Mineral Show image3icon 

Carnegie Museum of Natural History no longer presents the Carnegie Gem & Mineral Show. At this time we do urge gem and mineral lovers to visit the newly renovated Hillman Hall of Minerals and Gems and Wertz Gallery: Gems & Jewelry. Hillman Hall has undergone a tremendous renovation that allows us to exhibit more dazzling minerals and gems—many of which have never been on display—than ever before. Wertz Gallery is the new permanent home for the sparkling collection of Carnegie gems as well as a space for traveling exhibitions. Wertz Gallery features a dynamic roster of temporary exhibitions, including Pittsbugh Adorned: Classic to Contemporary and Garden of Light: Works by Paula Crevoshay.
