Sources of parti sapphires:

The mines from Montana, Kenya, and Australia are the primary ones where parti sapphires are found. Being the source with the most abundant supply, Australia is one of the most important and well-known parti sapphire suppliers, especially yellow ones. One of the major sources of sapphires has been in the eastern parts of Australia, which is where basaltic rocks that formed due to volcanic activity are present.

Montana parti sapphires come in blue, purple, and lavender zones. The parti sapphires from Kenya are found in a greener shade that seems to be going toward the color yellow. 

Colors of parti sapphires:

Parti sapphires are famous and unique because of their rare colors that have come about naturally. The iron imparts the yellowish brown color, while the blue tones are due to a higher concentration of titanium than that of iron. The green sapphire color is achieved if there is more of iron than titanium in the sapphire. Yellow and green parti sapphires are quickly becoming the most popular ones.

Parti sapphires in Australia are igneous in type meaning they contain iron in significant amounts. These iron levels lead to a darker hue in the gemstones. Parti sapphires from Australia will sometimes have all three colors of yellow, blue, and green, and sometimes a combination of only two of those colors.

There are distinct partitions (“parti”) among the multiple colors the gem has, thus giving you a stone that displays more than one color in a very clear way. Each parti sapphire stone is different from the other. Nature makes sure that no two parti sapphires will have the same color zoning. The color distribution is in such a way that they are complementary to each other.

Since darker tones in parti sapphires might dull down the effect of the color banding, consumers often go for medium-toned ones that show the multi-colored hues of the gem in just the right way. 

Teal sapphires vs Parti sapphires:

Teal sapphires have a blend of colors in them whereas parti sapphires have clear color zoning. Zoning happens primarily due to trace minerals interacting with the elements in the gemstone’s structure during its formation stage.

The main difference between a teal sapphire and a parti sapphire is that the colors in a parti sapphire will have specific zones with partitions. If there are clear partitions between two to three colors in the sapphire, then it is categorized as a parti sapphire. If a bi-colored sapphire from Australia is yellow colored, then it is almost immediately considered a parti sapphire.

Cuts you should go for: 

It is important to know which cut will ensure that you get the best out of the color zoning in your parti sapphire. Cuts should be made with precise and purposeful angles. Custom cuts are the way to go in the case of parti sapphires. The high level of iron in parti sapphires from Australia leads to a dark shade, so to reduce the intensity of the darkness, many of them are low heat treated. 

The parti sapphires from Australia are known to show their best form when cut at shallow angles. This makes the gemstone’s colors appear lighter and more brilliant. The gem cutter can get precise and creative to find the best way to enhance the different colors of this gemstone.

Mechanized mining operations make sure the sourcing of the sapphires is well organised. The working conditions for the miners are ensured to be fair. The mere mention of Australia guarantees that the sapphires will be mined ethically and with traceability.
