Ammolite is a vividly iridescent, fossilized shell derived only from certain ammonites in southern Alberta, Canada. The lead article in this issue explores the history, occurrence, and properties of this unusual gem material. Since significant commercial production began 20 years ago, Ammolite has been used to produce hundreds of thousands of pieces for the gem industry, primarily as assembled stones. The 18K gold pendant shown here was designed by Margo Searn of Jewels by Design (Calgary, Alberta). The triangular Ammolite (4.6 × 3.3 cm) is courtesy of Santo Carbone, Calgary; the three ovals, all Ammolite triplets, and the pendant are courtesy of Korite International, Calgary.
