Ammolite Stone Grading Quick Reference Guide 

See below for our standardized quick reference guide for ammolite grading – reviewing this material prior to making your ammolite gemstone purchase is key in helping understand what sort of colours, matrix lines, and brightness you can expect. Given the unique nature of ammolite gemstones, especially if you are shopping online, our recommendation is to opt for the finest gemstone within your budget – this way you will avoid disappointment. Please note that due to the extremely rare nature of AAA grade stones, KORITE’s dedication to upholding the finest quality possible, and the fact that it takes a long time to find the quality ammolite rough material – we tend to only build AAA grade stones upon request. Contact the KORITE Customer Service team to inquire about custom ordering a AAA Grade Stone.

Standard Grade Ammolite Stone

Standard grade ammolite stones are the starting point for our grading system. These stones typically display 1-2 colours and may include matrix lines. While they may not have the same vibrant colouration as higher-grade stones, standard grade ammolite stones can still make beautiful pieces of jewellery or collectibles. At KORITE International, we ensure that even our standard grade stones meet our high standards for quality and authenticity.

A Grade Ammolite Stone 

A grade ammolite stones are a step up from standard grade stones, displaying 2 or more colours in brighter tones than standard. These stones may also include matrix lines, but they still offer a vibrant and eye-catching display of colour. As with all of our ammolite stones, we carefully select only the best quality A grade stones to include in our inventory. 

AA Grade Ammolite Stones 

AAA Grade Ammolite Stones 

The highest grade of ammolite stones available, AAA grade stones display 3 or more vibrant colours from any angle and may have fine matrix lines that are barely visible. These stones are incredibly rare and valuable and represent the pinnacle of quality in the world of ammolite. At KORITE International, we are proud to offer a selection of AAA grade ammolite stones that are truly one-of-a-kind. To inquire about a AAA Grade Stone please Contact us as supply is very limited.

Colours in our Ammolite Stones 

Each ammolite stone is as unique as a fingerprint, displaying a wide range of colours that vary in intensity and hue. Standard grade stones typically display 1-2 colours, while A grade stones feature 2 or more colours in brighter tones. AA grade stones boast 3 or more bright colours, and AAA grade stones display 3 or more vibrant colours from any angle. These colours can include a stunning array of hues, from fiery reds and oranges to deep greens and blues.  

The occurrence of different colours in ammolite can vary depending on the specific deposit, but as a general rule, at lower grades, greens tend to dominate, along with possible reds and oranges. As the grade increases, you will begin to see a wider range of colours, including blues, violets, and other rare and vibrant hues. This is because higher-grade ammolite stones tend to exhibit more vibrant and saturated colours overall, with a greater range of hues and tones. At KORITE International, we offer a wide selection of ammolite stones across all grades, ensuring that our customers can find the perfect stone to fit their unique style and preferences. 

We hope this guide has provided you with a better understanding of our unique grading system and the beauty of ammolite stones themselves.
