teal Sapphire Sources
Myanmar, Sri Lanka, Kashmir, and Thailand may be the largest and traditional sources for sapphires and other gemstones; however, the leading source for Teal sapphires is Australia.
Purists only consider Australian teal sapphires to be genuine, but other sources have been discovered. Places such as Madagascar, Ethiopia, and Nigeria are new sources and Montana in the United States, which has become an essential gem source.
While purists are still not as devoted to these new sources, the stones mined there can be as beautiful and pure as those mined Down Under.
teal Sapphire Properties
Teal Sapphires, like all sapphires, are very durable. They measure 9 in the Mohs scale, second only to diamonds for hardness amongst natural gemstones. These stones are resistant to scratches and damage; therefore, they make ideal daily wear, such as engagement rings.
Most untreated sapphires will contain silk inclusions. However, these are rarely visible to the naked eye. Most teal sapphires will have internal flaws, but none will distract from the brilliance and shine of the stone.
teal Sapphire Colors
Many people label Teal sapphires as Parti-sapphires, although this is a mistake. The term parti means the colors of the stone are separated into distinct color zoning bands, and this is not the case for teal sapphires. Although, these gemstones do show a gradient of different shades alongside different degrees of blue, green, yellow, and space grey.
The most valuable examples of teal sapphires have an equal, or near-equal, composition of blue and green primary colors. They will also have hints of yellow, depending on the reflection of the light within the stone and the cut of this. The rarest form of teal sapphire has a 50/50 blue and green color composition, creating a mossy aquamarine-like color and hue.
Do Teal Sapphires Change Color?
Teal Sapphires do not show signs of pleochroism or the characteristic of changing color under certain lights. However, the reflection patterns under natural and artificial lights do produce a subtle and partial change. The yellow of artificial lighting does highlight the green tones in the gemstone.
