The six photographs to the right show examples of different stone setting methods. A and B are loop settings, C and D are channel settings, and E and F are prong settings. Differences in the width and thickness of the bars, or in the size of the prongs, are the result of an overall consideration of the style, durability, and wearability of the jewelry. The loop setting is an effective method of setting several gemstones in a row. A is set with ruby cabochons, and B is set with diamonds. The loops hold the gemstones securely in a characteristically neat fashion. Channel setting is a variation of bar setting, one that is especially elegant when the rails are made slightly high and the inner edges are smoothly finished. Prongs that are especially large, as in F, can help prevent jewelry from catching on clothing, and also serve to harmonize the strongly brilliant round diamonds with the somewhat less brilliant marquise diamonds. In this way, prongs can bring balance to an arrangement of diamonds with different personalities, and may serve as the focal point in the creation of a unique style.
