Abstract: A method of making jewelry in which liquid gold is shaped into the desired hollow configuration using centrifugal/gyroscopic motion. The gold is liquidified either before application to a mold or melted after it is deposited into the mold. A centrifugal force is applied to the mold to press the gold against the interior walls of the mold and the gold is allowed to solidify. Once solid, in the preferred embodiment, the gold is “hardened” using a pulse of air pressure applied to the interior of the mold.

Abstract: An improved method of constructing jewelry and other ornamental items in which the wall construction is significantly reduced due to internal envelopes or packets of pressurized gas. The packets of pressurized gas provide structural support for the surrounding walls permitting the walls to be thinner than the prior art. Manufacture of the jewelry is accomplished by creating the envelopes and sealing them either in raised pressure environment or later. Pressurization of an envelope is accomplished through different methodologies including: the insertion of a needle through the envelope's wall, pressurization of the interior of the envelope, removal of the needle, and then sealing of the hole created by the needle; through the use of pressurized spheres which are placed within the envelope during manufacture and then rupturing of the pressurized spheres after the envelope has been sealed; or using and then sealing a channel for pressurizing the internal envelope.
