Source: The provisions of this part 301 contained in standards for Navajo, Pueblo, and Hopi silver and turquoise products, Mar. 9, 1937, unless otherwise noted. § 301.1 Eligibility for use of Government stamp. Subject to the detailed requirements that follow, the Government stamp shall be affixed only to work individually produced and to work entirely hand-made. No object produced under conditions resembling a bench work system, and no object in whose manufacture any power-driven machinery has been used, shall be eligible for the use of the Government stamp. § 301.2 Specifications of material. Silver slugs of 1 ounce weight or other silver objects may be used, provided their fineness is at least 900, and provided further that no silver sheet shall be used. Unless cast, the slug or other object is to be hand hammered to thickness and shape desired. The only exceptions here are pins on brooches or similar objects; ear screws for earrings; backs for tie clasps and chains which may be of silver of different fineness and mechanically made. § 301.3 Specifications of dies. Dies used are to be entirely hand-made, with no tools more mechanical than hand tools and vise. Dies shall contain only a single element of the design. § 301.4 Application of dies. Dies are to be applied to the object with the aid of nothing except hand tools. § 301.5 Applique elements in design. All such parts of the ornament are to be hand-made. If wire is used, it is to be hand-made with no tool other than a hand-made draw plate. These requirements apply to the boxes for stone used in the design. § 301.6 Stone for ornamentation. In addition to turquoise, the use of other local stone is permitted. Turquoise, if used, must be genuine stone, uncolored by any artificial means. § 301.7 Stonecutting. All stone used, including turquoise, is to be hand-cut and polished. This permits the use of hand- or foot-driven wheels. § 301.8 Finish. All silver is to be hand polished.
