What is a Montana Sapphire?

If you have been looking for a unique engagement ring or a right hand ring for yourself that is not mainstream, chances are, you have come across “Montana sapphires”.

But what exactly are they?

The term "Montana" refers to a location, Montana US, which produces a gorgeous variety of green, blue-green and teal sapphires.

Many clients are now using “Montana Sapphire” as a colour reference rather than the source, which can get a little confusing.

For example: “Irina, I am looking for a Montana sapphire, but it doesn't actually have to be from Montana”, what they are looking for here is a blue-green or a teal sapphire.

Basically, some sapphires from Montana are blue-green, however not all blue-green sapphires come from Montana.

What other colours do Montana sapphires exist in?

Montana also produces a variety of blues, pink, yellow and green sapphires. The majority of sapphires from this location are less than a carat in size, so if you are looking for a larger stone in the 1 carat+ range, of a specific shape, be open to other locations.

No two Montana sapphires are alike, that’s the unique and exciting thing about them!

Are Montana sapphires the same as Teal sapphires?

The colour “teal” refers to a dreamy and mysterious combination of blue and green colours. A relatively new trend, teal sapphires are quickly making their way to the top of the wish list for many brides-to-be as well as trendy fashionistas.

You might also hear other inventive and fancy names like “mermaid sapphires” and “peacock sapphires”.

So, yes, some teal sapphires do come from Montana.

What about “parti-sapphires” ?

Other recent jewellery trends include “bi-colour sapphires” and “parti-sapphires”.

They show two or more distinct colours, for example blue and yellow (as in, the stone is partially blue and partially yellow, referring to colour zoning).

These, however are different to teal or blue-green sapphires, which show a combination of blue and green colours, rather than two or more distinct hues like below.

There are some "parti" sapphires that originate in Montana, others come from locations around the world.

Do Sapphires show "colour change"?

Sapphires can look slightly different in different lights, for example when you are sitting at home by a warm, yellow light lamp and when you in the bright sunshine outside.

This should not be confused with the “colour change” phenomena seen in rare alexandrite (below). This unique stone is green in daylight and red in warm candle light.

Other Sources

Blue sapphire and fancy sapphires (any colour other than blue) are found all over the world.

Sources of blue-green sapphire other than Montana, include Nigeria, Madagascar, Ethiopia and Sri Lanka. I recommend not focusing on the origin as much as the colour itself.

For example, if you are determined to find the perfect teal sapphire that comes specifically from Montana, your options could be much more limited.

Ethical Sourcing

Although Montana sapphires are often advertised as “ethically sourced”, you might be paying a premium, just for the name.

Ethically sourced materials are of utmost importance to me and I take pride in working with companies who supply responsibly sourced diamonds and gemstones from all over the world.

Are Montana sapphires expensive?

Although the prices for blue-green, teal and Montana sapphires are on the rise due to higher demand and rising popularity, they are still a less expensive option, compared to traditional blue sapphires.

And since you are getting a truly one-of-a-kind colour, when you choose one of these unique sapphires, it is a win-win situation!


I am predicting that prices of these gorgeous blue-green combos will only increase with time, so NOW is the perfect time to invest in one!

Heat treatment is an industry standard, in fact, almost 99% of sapphires are heat treated to enhance and stabilise the colour, it is a permanent process.

Non-treated sapphires are more rare and difficult to find.

The gorgeous sapphire I selected for Serena Ring is an exception. It has not been heat treated and has been graded as such by a third-party appraiser.
