Rating: Be the first to rate this gemstone

These lab created blue sapphires match the chemical properties of a natural sapphire, but unlike most natural sapphires, these are flawless.

Chemical Name: Al2O3, Brilliance: 1.77, Fire: 0.18, Hardness: 9, Luster: 9%

There are two levels of colour, top blue and medium blue. Like natural sapphires there are different intensities of blue in each stone ranging from high intensity to medium intensity. Top blue is the range of stones with the most intense blue and the medium range does not have such intense blue.
