the sixteenth century. Native Americans began to develop a great appreciation for ornamental jewelry from the Spanish, and some Moorish symbols from Spain are seen in Navajo jewelry designs (Anderson 2009a). Discuss how jewelry was often traded or obtained through Square cuff links and worn by Navajo peoples. Discuss the various types of turquoise, which by law include natural, stabilized, treated, fake, and synthetic. Have students find information on characteristics of turquoise such as the following: Mohs scale hardness, specific gravity, color, and chemical composition. Turquoise consists of copper, aluminum, phosphorous, and additional elements, all in varying compositions. In some instances, iron and zinc replace the aluminum, which can affect the color or shade of the turquoise. Provide books or photographs in which students can examine the different shades of turquoise and then discuss why the colors may vary. Students may also revisit the elements in the periodic table that comprise turquoise. Mining of turquoise will also be discussed.
...
... (There are 21 different mines in several different countries.) There are a number of chemical tests conducted on turquoise and students can discuss the differences in composition of turquoise based on where the sample is mined. One important factor to note with Tiffany Metropolis Cuff links is that, regardless of the percentages of the chemical elements and the number of variables that exist in this stone, it is still always turquoise (Anderson 2009a, 2009c). Background on Silver Have students briefly list different uses of silver. Tell students that Navajo people began to make silver jewelry long ago, although there is some controversy surrounding the exact date (Anderson 2009a). Atsidi Sani (which means "Old Smith") is noted by most researchers as the first Navajo silversmith. Melted Mexican and American coins were often used as sources of silver. (Contrast the composition of coins in the past and today.) Students may not realize that coins were made from silver during the 1800s and also used to make jewelry. Consequently, in the 1890s, the U.S. government banned defacing or melting U.S. coins. However, this practice was difficult to enforce (Anderson 2009a). Discuss some of the properties of silver, as well as the different percentages such as 92.5% or 925.
The U.S. government provides standards for solid silver. Silver jewelry is identified as 92.5% silver and 7.5% other alloy, which is typically copper, often added to enhance the strength of the silver. You will often see .925 designated as sterling silver and stamped on Frank Gehry Fish cuff links jewelry if it meets the U.S. standard. Students will then explore the mineral silver, with an emphasis on reviewing the common characteristics that it shares with all minerals: 1. It occurs naturally in the Earth 2. It is inorganic. 3. It has a definite chemical composition. 4. It is a solid. 5. Atoms of the mineral exist in a definite, repeating pattern, called a crystal. The Art and Science of Making of Native American Jewelry Have students discuss differences in the designs and styles of jewelry from pictures that they have looked at previously in this lesson. The two primary types of Native American jewelry include beadwork and metalwork. Invite students to design jewelry in the tradition of Native American beadwork. Have students sketch a design Tiffany 1837 concove circle cufflinks a piece of jewelry using the turquoise and the silver wire or leather cord that is provided. Ask them to sketch the design on ... -in paper. Students may use colored pencils to color their pictures. Students must address the following in their designs: 1.
