Historically, the colour teal referred to a common teal or Eurasian duck, and it referred to the blueish-green color around the bird's eyes. So, it comes as no surprise that when sapphires with a dark cyan-like hue were discovered, they were named Teal Sapphires

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 stones 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 gemstones, 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.

teal Sapphire Care

Teal sapphires have a hardness of 9 on the Mohs scale, so there are durable. The best way to clean them is with a soft toothbrush, warm water, and mild soap, free of abrasives. We recommend cleaning your teal sapphire in a bowl on a table; this way, you minimize the risk of dropping the stone in the sink or on the floor. Ultrasonic cleaning can be used on teal sapphires. Once your stone is clean, dry it with a soft towel.

If your stone is set in a piece of jewelry, remember that the materials holding the gem are softer than the stone, so clean them with more caution.

The best way to ensure the safety of your stone or jewelry is to get them cleaned by professional jewelers.
