star ruby

The ruby is a variety of corundum and derives its name from the Latin ‘rubeus’, meaning red. The term ruby first appeared only in the Late Middle Ages. Before that the stone was known in Italian as “carbonchio”, small piece of coal, on account of its colour, reminiscent of burning embers. Its typical inclusions are very fine rutile needles that intersect to form a lattice known as ‘silk’.
