Ammolite : What is it?
Ammolites are rare and valuable organic gemstones usually found along the slopes of the Rocky Mountains in the USA and Canada. Made from fossilized shells, these stones are made up of aragonites, the minerals found in nacreous pearls.
Also known as calcenites, korites, and aapoaks, ammonites were discovered in 1981. They were given official stone status in that same year by the World Jewellery Confederation.
Kinds of Ammolites include the following:
- Ammolite doublets have free form colors.
- They consist of minerazoled fossil shells.
- They usually have slight curves where color flashes roll off with movement.
- They usually come in green, orange, and yellow.
- They naturally have light refractive and dichromatic shift properties that provide color changes under natural daylight and fluorescent light.
- Ammolite triplets consist of a bottom usually made from the dark, gray layer of shale and a cap made with natural optical quartz or synthetic spinel.
- The top layer protects the entire stone from external factors and helps project its brilliant color.
- The bottom layer provides thickness and protection.
- They are sturdier and more durable for jewelry production than ammolite doublets.
- AA ammolite stones are graded with double A.
- They exhibit three or more brilliant colors in roughly equal proportions.
- A+ ammolite stones are graded with A+.
- They exhibit two to three brilliant colors.
- A ammolite stones are graded with A.
- They exhibit two or more light colors.
- Standard ammolite stones are usually gradeless.
- They exhibit one or more distinct colors.
- They are the dullest ammolites, having one comparatively dull, dominant color.
|Durability: For durability, choose red or green ammolites. Those in other colors are prone to scratching and breakage.|
Rarity: If you want rare ammolites, look for those with a crimson, violet, or gold color.
