AMMOLITE FROM CANADA
PARCEL
This is a natural parcel of specimens from Canada that is now ready for polishing or it can be kept as specimens.We have taken the photo with the stones wet. They have been treated to stabilize them-refer to the notes below.You also have the option to treat with opticon or liquid glass-it can be a challenge to get a good finish so you need to spend some time and experiment also but the results can be stunning.

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.
