Men's Marte ring in silver, perforated flat-top dome

Above the finger the ring rises into a wide dome, and the dome is not solid: it is a silver shell pierced with round and oval voids of different sizes, held together by the ribs of metal that run between one and the next. At the top, though, the shell does not end in a point or a cap — it is cut flat, in an oval plane, and that plane is the first thing you see when the hand is still. From below you look inside and there is nothing: the wall stands alone, and the light that comes in through the voids on one side leaves through those on the other. The band that carries all this is narrow and smooth instead, and passes under the finger without bulk. Outside the metal is re-polished on the ribs, inside and in the recesses it stays dark.

Twelve grams forty-five of silver at nine hundred and twenty-five thousandths, and it is all in the shell and the band: the dome is tall and wide but does not weigh what it seems to, because it is hollow. It is the reason a ring of this bulk can be worn, and at the same time the reason it is difficult to make — behind the wall there is nothing holding the metal up while it is being opened, and the solid that remains between one void and the next is all the structure the ring has. The flat top is stated by the company and it is what separates it from the other silver Marte pieces, which are the same design with a round dome or with a straight band. The company states it as a man's ring. The presentation box is included, and on request the same model is made in gold.
