Canadian Ammonite - 33(B100)

Placenticeras costatum measures 52 cm (20.5 in) and weighs 11.5 kg (25.3 lbs).

This extraordinary Ammonite is adorned with some of the rarest and most coveted colours found in gem-quality Ammolite—deep blues, rich purples, and striking indigos ripple across its surface, revealing the essence of Canada’s national gemstone in its most exceptional form.

Unlike most fossilized Ammonites, this specimen’s chambers remained unfilled during preservation, resulting in a uniquely thin layer of nacre. This rare geological phenomenon intensifies the brilliance of the iridescence and makes this one-of-a-kind fossil even more precious.

Sourced from the top of the Bearpaw Formation at the KORITE mine in Alberta, this Ammonite is a stunning example of the natural transformation that occurs over millions of years. Here, in the only region in North America where gem-quality Ammolite is found, ancient marine life has become radiant works of art.

KORITE’s expert craftsmanship and ethical mining practices ensure that the natural beauty and integrity of each specimen shine through. This Ammonite showcases not just colour—it embodies the legacy of our land and the allure of Ammolite as a globally recognized treasure.

This specimen comes with a handcrafted wooden display stand, a certificate of authenticity, and all necessary permits and customs documentation for international shipping. KORITE is not responsible for any import duties or taxes that may apply.
