Beautifully balanced, the Mathilde necklace features a 1″ concrete sphere suspended below a smaller stainless ball. The piece can slide either up or down to hang the spheres low or high.

Technically referred to as 253, Mathilde is a main-belt asteroid about 50 km in diameter. It has a relatively elliptical orbit that requires more than four years to circle the Sun. It is a primitive C-type asteroid, which means the surface has a high proportion of carbon; giving it a dark surface that reflects only 4% of the light that falls on it. One scientist said the asteroid is “blacker than coal” or twice the darkness of charcoal.
