Selected study unit - Gems-Minerals-Jewelry Study Unit

It is possible that the earliest collections that were ever assembled may have been rocks that were picked up from around the collectors' homes. The rocks could have formed interesting shapes or had unusual colors. As technology improved, the ability to identify and use the rocks that were collected also improved, pushing technology itself even further through the use of smelted metals. Other rocks would have been saved for their aesthetic qualities and set into intricate patterns of metals forming jewelry. The Gems-Minerals-Jewelry Study Unit examines the appearance of these items in philatelic materials. Membership in this study unit includes a subscription to the quarterly Philagems International journal.
