Mare Tranquilitatis or Sea of Tranquility it's an area on the Moon, a lunar sea. When I first came across this name I fell uner its spell. I waited for the right stone and the right design to use it - such a charming name deserves a very special piece of jewellery.
And this is it: this large Labradorite, flashing with heavenly azure-blue shades brings to mind a place of calm, quiet and magical atmosphere: a lunar ocean, sea on the Moon. I know in reality it's not blue, I know there is no water in it but it doesn't matter. It is blue in my dreams.
