Jewelry design is the art or professional of creating, crafting, fabricating, or rendering designs for jewelry. This is an ancient practice of the goldsmith or metalworker that evolved to a billion-dollar industry with the odyssey from ancient cultures into the machine age. Jewelry design falls under the category of what is commonly known as "functional art", being art that can be worn or used.

Before an article of jewelry is created, it is typically rendered by a jewelry designer, a professional who is trained in the architectural and functional knowledge of not only metallurgy but also design elements such as composition and wear ability.

Once the article is rendered, the design is then constructed using the necessary materials for proper adaptation to the function of the object. For example, 24K Gold was used in ancient jewelry design because it was more accessible than silver as source material. Before the 1st century many civilizations also incorporated beads into jewelry. Once the discovery of gemstones and gem cutting became more readily available, 2.the art of jewelry ornamentation and design shifted. The earliest documented gemstone cut was done by Theophilus Presbyter (c.1070 - 1125). who practiced and developed many applied arts and was a known goldsmith. Later, during the 14th Century, medieval lapidary technology evolved to include cabochons and cameos.

Early Jewelry design commissions were often constituted by nobility or the church to honor an event or as wearable ornamentation. Within the structure of early methods, enameling and repouss?became standard methods for creating ornamental wares to demonstrate wealth, position, or power. These early techniques created a specific complex design element that later would forge the baroque movement in jewelry design.

925 Sterling Silver Jewelry:

Sterling silver is an alloy of silver containing 92.5% by weight of silver and 7.5% by weight of other metals, usually copper. The sterling silver standard has a minimum millesimal fineness of 925.

Fine silver (99.9% pure) is generally too soft for producing functional objects; therefore, the silver is usually alloyed with copper to give it strength, while at the same time preserving the ductility and beauty of the precious metal. Other metals can replace the copper, usually with the intent to improve various properties of the basic sterling alloy such as reducing casting porosity, eliminating firescale, and increasing resistance to tarnish. These replacement metals include germanium, zinc and platinum, as well as a variety of other additives, including silicon and boron. A number of alloys, such as Argentium sterling silver have appeared in recent years, formulated to lessen firescale or to inhibit tarnish, and this has sparked heavy competition among the various manufacturers, who are rushing to make claims of having the best formulation. However, no one alloy has emerged to replace copper as the industry standard, and alloy development is a very active area.
