For rough ammolite visit our sister store MINERAL GEM WORLD under Canadian ammolite.

Ammolite is a rare and valuable opal-like organic gemstone found primarily along the eastern slopes of the Rocky Mountains of the United States and Canada. It is made of the fossilized shells of ammonites, which in turn are composed primarily of aragonite, the same mineralthat makes up nacreous pearls.

An iridescent opal-like play of color is shown in fine specimens, mostly in shades of green and red; all the spectral colors are possible, however. The iridescence is due to the microstructure of the aragonite: unlike most other gems, whose colors come from light absorption, the iridescent color of ammolite comes from interference with the light that rebounds from stacked layers of thin platelets that make up the aragonite. The thicker the layers, the more reds and greens are produced; the thinner the layers, the more blues and violets predominate. Reds and greens are the most commonly seen colors, owing to the greater fragility of the finer layers responsible for the blues.

Treatments Although fully mineralized and containing no water—and therefore not subject to dehydration and subsequent crazing—ammolite is often damaged due to environmental exposure. The thin, delicate sheets in which ammolite occurs are also problematic; for these reasons, most material is impregnated with a clear epoxy or other synthetic resin to stabilize the flake-prone ammolite prior to cutting. Although the tessellated cracking cannot be repaired, the epoxy prevents further flaking and helps protect the relatively soft surface from scratching.

「自動入札」を示すアイコンがある場合、システムが最高入札額に基づいてユーザーに積極的に入札していることを意味します。これは、ユーザーが自分自身を上回って入札しているように見えるかもしれませんが、ユーザーの上限を反映するためにシステムが入札を更新した結果にすぎません。
