When we think of blue gemstones, most people picture sapphire first.
But for those who truly love blue, deep, vivid and full of light, blue spinel is an exceptional option!
While sapphires are often heated to enhance their colour, fine blue spinel is almost always unheated. Its colour is completely natural and due to trace elements like cobalt and iron in the crystal structure.
And it’s not just about colour. Spinel has a very high refractive index, which means it reflects light beautifully!
That brilliance gives it a lovely, sparkly appearance that is rare in darker toned gems.
