Parti sapphires

Another commonly used terminology when it comes to sapphires is parti sapphire, which basically refers to a ‘partition’ between the colors of these gemstones. These stones occur in a blend of various colors like green or blue with yellow. Unlike teal sapphires, the colors in parti sapphires have a distinct demarcation which forms two different bands known as color zones. Another distinct feature that makes them different from teal sapphires is the consistent display of colors. Parti sapphires appear the same in different lighting conditions, unlike teal sapphires that change their hues depending on the light source. Parti sapphires are just as popular as teal sapphires, owing to their unique esthetics. The buyer’s guide to parti sapphires explains the commercial aspect of these stunning gemstones better.

Bicolor sapphires

Bicolor sapphires include any sapphire stone with two distinct colors. The term bicolor is more popularly associated with tourmalines rather than sapphires. Since tourmalines cost significantly less than sapphires, the term bicolor is rarely preferred while describing the more luxurious sapphires.

A point of difference between these two, is that tourmaline typically has a very neon appearance. This means that they have a much more open color, while teal and mermaid sapphires have a much more saturated tone.

Blue green sapphire

Another name that is widely used to describe teal sapphires is “blue green sapphire”. This merely describes the two-color tones found in these gems and can be used to denote any sapphire that occurs in blue and green hues. For the stone to be considered teal, it should have the combination of royal blue and dark green.

Color changing sapphires

Color changing sapphire primarily indicates any sapphire that exhibits a dominant color change in different lights. For example, bluish green to purple in natural light. Note that teal sapphires do not change their colors in different lighting conditions. However, they may appear different in natural and artificial light due to their reflection patterns. 

Green sapphires/Green teal

The term green sapphires is used to denote sapphires that have a dominant green tone. Any sapphire with more than 90% of green hue can be called as green sapphires. Sometimes, customers use the term ‘green teal’ to refer to any teal sapphire with more green tinge. 

Montana sapphires

Many buyers/traders sometimes refer to teal sapphires as Montana sapphires. However, the term Montana sapphires merely represents the origin of the sapphire stone rather than its nature. While they could be teal sapphires, they may also denote any other sapphire gem mined from Montana.
