Ammolite is Classified as a True Gem

One of only three named in the last 300 years

Ammolite originates from prehistoric marine fossils that date back 71-million years. Tectonic pressure, heat and mineralization formed the gemstone, almost exclusively harvested by KORITE.

KORITE discovers and hand cuts the ammolite gem to maximize the inherently bright colours. The luminous colour in each gem is unique. Multiple layers of the natural gemstone material create a beautiful array of colour.

This rare, natural expression of the spectacular gem is believed to awaken positive energy with its joyful beauty and ancient heritage. Wearers and collectors call them gems of enlightenment.
