In the early days of rockhounding in America it seemed like there was an endless abundance of wonderful agates and jaspers. The hobby of making cabochons grew so large that it was second only to woodworking as the most popular hobby in the US. During that time the great agate discoveries were exploited freely and many were quickly exhausted. Beautiful material was usually cut into slabs and the slabs were used to produce cabochons. It is still possible to find slabs that were set aside by collectors or were never cut into cabochons but it was uncommon to cut a rock in half and polish the face. Toward the end of that period I was making my living cutting cabochons but I was also a collector and a painter and when I saw a slab that was highly artistic I rarely cut it into cabs, it went into my slab collection.
Those who wish to collect the fine early materials should recognize that for the moment it is still possible to collect fine slabs and they offer many advantages to a collector. They are easy to store and display and they are reasonably priced given their rarity and beauty. Slabs and half nodule specimens can be combined in a display with the heavier specimens in the foreground and slabs mounted on stands above and behind them.
A few dealers at today’s rock shows still offer fine polished slabs of the rare early materials but it is not often that one sees a specimen of great beauty that is a saw cut rock with a polished face.
Precision polishing of a flat surface requires special equipment and knowledge and that may have further lessened the interest in flat lapping during the cabochon era.
