Madagascar star sapphires from Ankarana frequently display excellent asterism. Our photographs are taken with a fiber optic light above the stone. The stars will look like this in sunlight or under a spotlight. The denim blue color of Madagascar Star Sapphires can be quite even except for the crystal growth lines which prove that the stone is natural.

A great stone for a man's or women's ring, natural star sapphires are never clean. It is the silk inside them that accounts for the asterism and clean stars do not exist.

In terms of price and quality, blue star sapphires from Madagascar are incomparable in value. Ceylon and Burma both produce limited quantities of blue stars but although they may occasionally be better in quality, their prices are normally substantially higher.
