Which Natural Sapphire Colour Is the Rarest?
By Clint Casmiro, Co-Founder, Smiro Studio, Toronto · Updated October 6, 2026
Short answer: From most affordable to rarest, natural sapphires go roughly yellow, then green and teal, then blue, then pink, and the rarest colour of all is padparadscha, a mix of pink and orange. Two sapphires can be the same weight and the same shape and still be thousands of dollars apart. In our video, one is about $1,000 and the other is $37,000. Colour and where the stone comes from make that difference.
Make sure you know this before you pick a natural sapphire for your engagement ring. Sapphires come in almost every colour, from mines all over the world, and the price follows how rare the colour is.
Why can two sapphires of the same size cost so differently?
Sapphire is priced on colour first. The more saturated and the rarer the hue, the higher the price per carat. The source matters too: some regions are known for a colour that buyers pay a premium for. That is how a stone of the same weight and shape can be a few hundred dollars per carat or tens of thousands.
Which sapphire colour is the most affordable?
Yellow. Most yellow sapphires come from Sri Lanka, with more from Thailand and Madagascar. A good yellow can be a couple of hundred dollars per carat, which makes it the easiest way into a natural sapphire.What about green, teal and Montana sapphires?
The next step up is green and teal, including bi-colour stones that shift between the two. Montana sapphires come mostly in that blue-green teal and have been getting much more popular, especially in North America. Australia and Nigeria also produce greens.
How rare are blue sapphires?
Blue is the colour most people picture, and it covers a huge range. Sri Lanka gives brighter, lighter blues. Australia gives deeper, darker blues. Madagascar can rival the classic sources, and Burma is known for rich royal blues. The most expensive blue of all is from Kashmir in northern India: a soft, velvety royal blue that can sell for over $100,000 per carat. Very few Kashmir stones ever come to market.
Are pink sapphires rarer than blue?
Pink sits above most blues. Pink sapphires come from Madagascar, Sri Lanka, Mozambique, Tanzania and Burma, and the more intense the pink, the rarer and more expensive the stone. You can see real stones in our natural pink sapphires collection, and compare them with lab pinks in pink lab diamonds vs natural pink sapphires.
What is a padparadscha sapphire?
Padparadscha is the rarest sapphire colour you can get: a soft blend of pink and orange, often compared to a sunset or a lotus flower. Sri Lanka is the classic source, with stones also found in Madagascar and Tanzania. True padparadscha needs both colours in balance, which is why so few stones qualify. We have one in stock, a 3.34 carat oval padparadscha.
How do the colours rank?
| Colour | Main sources | Rarity |
|---|---|---|
| Yellow | Sri Lanka, Thailand, Madagascar | Most affordable |
| Green and teal | Montana, Australia, Nigeria | Next tier up |
| Blue | Sri Lanka, Australia, Madagascar, Burma, Kashmir | Wide range; Kashmir is the top |
| Pink | Madagascar, Sri Lanka, Mozambique, Tanzania | Rarer as the colour deepens |
| Padparadscha | Sri Lanka, Madagascar, Tanzania | Rarest |
Which sapphire should you choose for an engagement ring?
Pick the colour you love first, then the budget. If you want something truly rare as a centre stone, padparadscha or a strong pink is the way to go. If you want colour without the price of the top tiers, a teal Montana or a bright Sri Lankan blue gives you a natural stone with a lot of character. Sapphires are hard enough for everyday wear, so any of them can be an engagement ring. We source stones for you and show you real videos before you decide.

What is the rarest sapphire colour?
Padparadscha, a balanced mix of pink and orange. Kashmir blue is the most valuable blue, but padparadscha is the rarest colour.
Are natural sapphires good for engagement rings?
Yes. Sapphire is very hard and stands up well to daily wear, which is why it is one of the most popular coloured centre stones.
Why is a Kashmir sapphire so expensive?
The mines produced for only a short time and very little has come out since, so stones with that velvety royal blue are extremely scarce.
Can you set a natural sapphire in a tulip basket?
Yes. Any of our settings work with a sapphire centre, and sapphires can also go inside the petals. See sapphires in tulip basket petals.
