The Science Behind the Sapphire
Sapphires, birthed from the belly of the Earth, are crystalline forms of aluminum oxide, embellished with traces of iron and titanium.

Meanwhile, in the Middle Ages, clergy wore blue sapphires as a symbol of heaven, and the common folk believed it brought divine blessings.

Grading Sapphires: Determining Value
The value of a sapphire is judged on the grounds of its color, clarity, cut, and carat weight—collectively known as the 4Cs. Of these, the color holds paramount significance. The most coveted sapphires boast a vibrant, medium-dark blue hue, with excellent clarity and a brilliant cut that showcases the stone’s depth and luminosity.
