Do any bees have any ammolite jewellery? I’m seriously loving this gemstone! Here are some examples…
What do you guys think? I think the history is cool and apparently they are pretty rare. I know its a little “mood ringy” but I like it. Here’s some info…
Ammolite is formed from an ancient marine fossil called ammonite. Although sources of ammonite exist in other locations around the globe, it is only in one isolated region of Southern Alberta, Canada, that this deposit produces the gemstone Ammolite. Seventy-one million years of tectonic pressure, heat and mineralization have resulted in the formation of this geological wonder.
The supply of Ammolite is extremely limited and with only one area for mining, Ammolite truly is one of nature’s rarest gems. Korite’s eco-friendly Ammolite mine produces over 90% of the world’s supply of this incredibly rare gem. At current production levels supplies of high grade ammolite are expected to be completely exhausted in approximately 20 years. See photos of Korite’s mining operation here.
The color present in Ammolite is caused by light interference during refraction into the many layers of the gemstone. Each color in Ammolite represents a different layer of the gem material. So, depending on the number of fine layers in the rough, everything from one color to the full visible spectrum will be displayed. Since the play of light varies, every Ammolite gem shows a unique array of color. See photos of different Ammolite gems here.
The natural hardness of Ammolite is 3.5 to 4.0 on the Mohs scale. However, Korite International caps the Ammolite gem layers with a protective spinel crystal, increasing the hardness to an exceptionally durable 8.0. These assembled gemstones are known as triplets and, when set in gold jewellery by Korite International, are covered by Korite International’s conditional lifetime guarantee.
Ammolite comes from the fossil shells of the Upper Cretaceous disk-shaped ammonites Placenticeras meeki and Placenticeras intercalare, and (to a lesser degree) the cylindrical baculite, Baculites compressus. Ammonites were cephalopods, or squid-like creatures, that thrived in tropical seas until becoming extinct along with the dinosaurs at the end of the Mesozoic era.
The ammonites that form ammolite inhabited a prehistoric, inland subtropical sea that bordered the Rocky Mountains—this area is known today as the Cretaceous or Western Interior Seaway. As the seas receded, the ammonites were buried by layers of bentonite sediment. This sediment preserved the aragonite of their shelled remains, preventing it from converting to calcite.
