Grading Criteria for Ammolite
The quality and value of Ammolite are determined based on several key factors: colour, brilliance, clarity, and the extent of the gemstone’s play-of-colour. Let’s break down each of these criteria:
Colour
- Hue: The primary colours in Ammolite are red, green, and blue, with rarer hues like gold and purple being highly prized. The presence of multiple vibrant colours enhances the gem’s value.
- Range: High-quality Ammolite exhibits a wide range of colours. A stone displaying all seven spectrum colours (red, orange, yellow, green, blue, indigo, violet) is considered exceptional.
Brilliance
- Intensity: Brilliance refers to the intensity and brightness of the colours. The more vivid and bright the colours, the higher the grade.
- Movement: The colours should remain bright and change as the stone is viewed from different angles, showcasing the gem’s dynamic nature.
Clarity
- Inclusions: Clarity is assessed based on the presence of natural inclusions or fractures. Fewer inclusions indicate a higher quality stone.
- Surface condition: The surface should be smooth and free from cracks or blemishes that could affect the stone’s durability and appearance.
Play of Colour
- Uniformity: The distribution of colour across the surface should be even and continuous. Stones with patchy or spotty colour distributions are less desirable.
- Pattern: The patterns in which the colours appear, such as ribbon, mosaic, or sheet patterns, can also influence the stone’s appeal and grade.

Why Ammolite Grading is Unique
Grading Ammolite gemstones is distinct from grading other coloured gemstones due to several unique factors:
- Organic origin: Unlike many coloured gemstones that are minerals, Ammolite is an organic gemstone, formed from the fossilized shells of ancient ammonites. This organic origin contributes to its unique iridescence and the variability in its patterns and colours.
- Microstructure of Aragonite: The play of colour in Ammolite is due to the microstructure of aragonite, which is different from the crystal structures found in other gemstones like sapphires or emeralds. This unique structure results in the gemstone’s characteristic iridescence.
- Colour play and pattern: While many coloured gemstones are valued for their single, intense hue, Ammolite is prized for its display of multiple colours and the specific patterns these colours form. This dynamic colour play sets Ammolite apart from other gemstones.
- Rarity and source: Ammolite is found only in specific geological formations in Alberta, Canada, making it rarer than many other coloured gemstones that can be sourced from multiple locations worldwide.
