An iconic and timeless gemstone, blue sapphire captivates with its rich colour, ranging from light blue to deep, velvety shades. Part of the corundum family, it is distinguished by its exceptional hardness, durability and brilliance. A symbol of fidelity and commitment, blue sapphire offers an elegant alternative to diamond and brings distinctive depth to each creation.
Origins and characteristics
Some of the finest blue sapphires come from Sri Lanka, Madagascar, Kashmir and Myanmar. Their colour is primarily due to the presence of iron and titanium in the corundum. With a hardness of 9 on the Mohs scale, sapphire is one of the most durable gemstones, making it particularly suitable for everyday wear while retaining its brilliance.
How to choose a blue sapphire
Choosing a blue sapphire is primarily about its colour, intensity, saturation and colour distribution within the stone. Sapphires with a vivid, deep and even colour are particularly sought after. Untreated stones are rare and highly prized, while heat treatment is commonly used to improve the colour and transparency of some sapphires.
The value of a blue sapphire depends on factors including the intensity and quality of its colour, its clarity, cut, carat weight and whether it has been treated. Untreated sapphires with exceptional colour can be extremely rare, especially in larger sizes. Each stone is selected for its balance, brilliance and the distinctive character it brings to the creation.
