The above-listed elements of the eyewear device are preferably composed of one of a plurality of precious metal alloys. In certain aspects, the frame may be composed of the same precious metal alloys as the plurality of temple elements; in alternate aspects, the frame and temple elements may be composed of different precious metal alloys. The eyewear device may be or comprise a plurality of precious metal alloys, including but not limited to gold, silver and/or palladium. Further presented is a joining apparatus, wherein the elements of the joining apparatus are composed of a precious metal alloy which is harder and/or has a higher specific gravity than that of the frame and temple elements. ## Claims ### Claim 1 An eyewear apparatus comprising: a frame adapted to house an optical element, the frame substantially comprised of a first precious metal alloy;
