Indigo and green flashing 20.10ct Mosaic Ammolite

The mosaic effect of this Canadian ammolite is simply gorgeous! Each window of color shifts between rich indigo and vibrant greens and teals creating an almost stained glass effect. This all natural play of color flows like water over the gems face and really shows the rare beauty of fossilized opal. Measuring 19mm x 17.8mm x 5.4mm this piece has amazing size, and its protective cover has been polished to a liquid luster.

To protect the delicate nature of ammolite opal, most cabochons receive a protective resin coating, but this high quality piece has been coated with a two-part epoxy, providing it with superior protection and giving it a Mohs hardness rating of approximately 8 out of 10 making it incredibly durable. This means that your ammolite is perfect for setting and daily wear, and can be polished if needed.
