DUNCAN POPPY JASPER

Rock&Gem Magazine

|

September 2025

Every year comes the chance to find something new, whether in the field or the marketplace. This year, a new type of jasper appeared in the rockhound community on Facebook, catching quick attention for its bright variety of colored poppy jasper.

DUNCAN POPPY JASPER

Duncan poppy jasper is found along the Arizona/New Mexico border and is a brand-new find by journeyman Tim George. On one of his adventures hiking across old volcanoes, he discovered a small deposit of this cranberry-colored poppy jasper. In his recollection, he realized he missed the first deposit by 50 feet.

This bright new material contains various colored poppies, prominently deep reds and oranges, with one variety being pastel purple and pink flowers too. Often, you will find many quartz crystal pockets and agate veins running through, making for great fun designing shapes to cab.

WHERE TO PURCHASE SLABS

Though it’s limited because it’s a recent discovery, you can obtain some by contacting Tim George on Facebook, where he posts weekly sales of his many finds.
