This ring is a CAD design, using Matrix. It is constructed from 6 cast pieces in sterling silver. It is soldered together, then the seams are laser sintered and filed back for accuracy. The ends of the spray and the ring interior are stopped off to protect the surface, while the rest of the ring is sandblasted, then rhodium plated. The sandblast gives a great surface, that sparkles, and the rhodium plate gives the colour of platinum, and wont tarnish. There are earrings and pendant also.
