Up to this point in time all jewelry was the end product of a small handcraft industry. Now, in the eighteenth century, factory-made ornaments began to appear. As with so many other everyday objects, quality suffered and the jewelry making art went into decline. The changes were not all negative. Jewelry wearing was finally brought to all the people by less expensive mass production; it was no longer considered a social privilege. True, certain kinds of very expensive jewelry are still indicators of economic privilege, but there is beautiful jewelry available for all. The new technology introduced another noble metal—platinum —for use in jewelry. Mechanization, too, allows for rapid changes in jewelry styles to match changes in styles of dress. Oddly enough, the popularization of jewelry has also brought about a strong revival of interest in new jewelry designs and in individually hand-crafted pieces. Each year, for example, awards are made for original designs entered in the International Diamond Awards competition. There are always some very imaginative pieces among the winners, which serve to encourage still more skilled artists and designers to apply themselves to this ancient pursuit.

There is considerable labor and time involved in progressing from design to finished jewelry piece. Casting, where feasible, is a method for reproducing a piece exactly, rapidly, and inexpensively. A mold is made of the model diamond jewelry piece, using a special fine sand mixed with water and glycerine. The mold is divided, the model is removed, the mold is reassembled, and molten metal is poured in through an opening previously prepared for the purpose.

When it cools, the new cast is taken out, excess metal removed, and finishing touches made. This kind of casting can only be done if the model is relatively simple and has no undercuts.
A far better casting process, especially for very accurate reproduction of delicate pieces, or those of some complexity, is the “lost-wax” method of centrifugal casting cushion cut diamond rings. The metal object to be reproduced is first copied exactly by making a rubber mold.  In turn,  the mold is used to make one or several copies in wax.

The wax commonly used is similar to dental wax, with a melting point between 150 and 170 degrees Fahrenheit. Casting waxes are available in blocks or partially formed rings from which a model of a jewelry piece can be created directly by filing, sawing, and carving. The wax is much easier to work with than the metal itself. By either route—rubber mold or direct work in wax—the wax model is prepared, embedded in a plaster-of-Paris and silica mix to form a new, high-temperature mold. This is now heated in an oven to about 1300 degrees Fahrenheit. The mold hardens princess diamond wedding ring, and the wax melts and runs out. To insure complete penetration and casting of every detail when the molten metal is poured in, the mold and its contents are spun in a small centrifugal machine. This packs the metal into every fine detail of the mold made by the “lost wax.” If carefully done, the finished casting requires very little filing or trimming when it is removed from the mold.

The Egyptians and Indians had some appreciation of color in their cheap diamond jewelry. They added manufactured and natural stone and enameling to it, but by and large the best jewelry of most of the ancient world was wrought only in gold. However, by the time of Alexander the Great—about 350 B.C.—gem-stones were more frequently found in Greek jewelry. Rock crystal, agate, sardonyx, carnelian, and even emerald added color. Interest in polychrome jewelry diamond solitare earrings increased, stimulated by contact with Persia. The most riotous use of color in jewelry developed among Indian civilizations along the Indus River. An abundance of colored gemstones in this part of the world, the availability of pearls, and a knowledge of the techniques of colored enamel and glassy paste combined to make it possible.

By the time of the Romans, whose jewelry styles were based on neighboring Greek and Etruscan forms, the various pieces were primarily prized for the massive load of gems they carried. The art of the setting was considered relatively unimportant. When Byzantine jewelry finally evolved, its style was based on those of Greece and Rome but was far richer and more dazzling in color and design because of influences from the east. Tastes in jewelry design by the Middle Ages were governed largely by the ostentation of the display. Enormous and massive creations featuring girdles and large brooches of gems and metal-work were very popular. Later, during the Renaissance, there came along with social, religious, and political changes a revolution in diamond jewelry design. Great artists, such as the Italian sculptor Benvenuto Cellini (1500-1571), the Flemish painter Peter Paul Rubens (1577-1640), and the Florentine sculptor Lorenzo Ghiberti (1378-1455), turned their attention to the design and production of jewelry. Their designs helped so much to enhance the beauty and popularity of gemstones and pearls that, by the late seventeenth century, the craft passed into the hands of the gem cutters and mounters. At the beginning of the eighteenth century there was a sudden surge of interest in highly intricate ornaments of over-enthusiastic design. Reaction was swift and tastes turned back again toward the early classic forms of jewelry. At this time design your own wedding ring , too, there was a great increase in the production of inexpensive jewelry pieces for the new, expanding, more affluent middle class.

The ancestry of the jewelry we know can be traced in large part back to its origins in Mesopotamia. The great early civilizations developed along major river valleys. The Su-merian civilization was born in Mesopotamia between the Tigris and Euphrates Rivers. Egypt rose along the Nile. India ascended from the Indus River and, in the Far East, China developed on the banks of the Hwang. As these civilizations prospered, so did their goldsmiths. It seems certain that Sumerian o;old-smiths had developed the art and craft to a high degree for their own use by 3000 B.C. Remarkable jewelry pieces have been recovered by archeologists during systematic excavations around Ur of the Chaldees, a great city which was the center of Sumerian culture at that time. In one grave—for Queen Shubad —there was an incredible cheap engagement rings treasure trove. The Queen herself had a kind of beaded coverlet made of gold, silver, lapis lazuli, carnelian, and other kinds of chalcedony. By her side were found hairpins of gold with lapis lazuli heads. She wore ornate head ornaments fashioned of gold rings, leaves, and flowers. Her ladies-in-waiting—buried with her along with all her other attendants—wore gold diadems and other jewelry.
