Blue Sapphire price and value
How much the blue sapphire worth? The value of Blue Sapphire is very variable. It depends on a number of criteria: its color intensity, clarity, weight, origin and rarity. It is important to note that the price of sapphire increases exponentially with its weight. This is because the larger the gemstone, the rarer it is. For example, a good quality 1ct heated blue sapphire will cost about $1100/ct (€1000/ct) while a 3ct blue sapphire of the same quality will cost about $2100/ct (€2000/ct).
Another factor that contributes greatly to the price of blue sapphires is the heat treatment. Indeed an unheated stone will cost about 30% more for stones of 1 to 2ct, and can be multiplied by 10 or more if you exceed a certain weight.
Today the most expensive and also the rarest blue sapphires are those from Kashmir. The most beautiful of them are traded at several tens of thousands of dollars per carat. In 2021, a 27ct Kashmir Blue Sapphire was sold at auction for 2.1M€ ($2.25M).
Other blue sapphires in high demand and much more affordable are those from Sri Lanka and Madagascar, which are in very good quality. In this case, for the same quality stone, a Sri Lankan blue Sapphire will be more expensive than a Madagascar blue Sapphire.

Blue Sapphire origins
Blue sapphire is mined in many countries. Some are more famous than others:
Sri Lanka: Sri Lanka still provides the majority of blue sapphire on the market today. This gemstone has been extracted there for centuries. One of the most famous blue colors is even called "Ceylon Blue".
Madagascar: This is now the second largest source of sapphire. Madagascar is known for providing very good quality sapphires. But the supply is sometimes difficult due to the moratorium of the authorities on the exports.
Kashmir: This is probably one of the least known origins of the public and yet it is in this region that some of the most beautiful sapphires in the world have been extracted. These mines hardly produce sapphires anymore, which is why these stones are so rare.
Australia: They are extracted mainly from the region of New South Wales and Queensland.
Blue sapphire is also found in Burma, Thailand and Montana in the USA.
Blue Sapphire colors
Blue sapphires come in a variety of hues.
One of the most popular colors on the market today is the Cornflower color which is a deep blue color that is neither too light nor too dark.
Royal Blue is also a classic, the hue is a deep blue comparable to Navy.
The light blue shade characteristic of Sri Lanka, Ceylon Blue is also very popular.
Finally the color Blue Kashmir, typical of blue sapphires from this region are a deep, silky blue with a slight hint of purple.
Each color has its specificities and are not negotiated at the same price.
Blue Sapphire characteristics
Blue sapphire can contain inclusions like all colored gemstones, but it is easier to find them with few inclusions than emeralds or rubies. Pure blue sapphires with a magnifying glass are however very rare.
Like ruby, its hardness is 9 on the Mohs scale, which makes it particularly ideal for mounting in jewelry.
Blue sapphires are often heated. Although this does not have a negative impact on the quality of the gemstone, it does have an impact on the price of the gemstone.
