In the jewelry production business there are four basic types of stone settings. The jewelry designers, manufacturers, goldsmiths make their products according to this styles.
The prong is the most popular setting. A prong is a narrow piece of metal that folds over the edge of the gemstone to secure it. A prong setting appears to elevate a stone higher than in other settings, and is used most often with diamond solitaires.
Invisible setting is relatively new. Calibrated stones with slits are placed into a frame with ridges to hold them in place. No metal appears between any stones. This setting only employs baguettes and princess cuts or a combination of both.
Smaller stones are closely set in a row between two metal walls. No metal appears between the stones. Channel settings often include square and baguette stones. They are frequently used in engagement bands or as side accents to a center stone.
The word actually comes from the French word to pave because of its paved look. The round stones are patterned very closely together and the only metal visible is what is actually used to hold the stones in place.
This type of setting is only used with round diamonds. It is a new style of setting in the jewelry market. The jewelers use magnifying glasses to set the stones because the stones are very small 0.01pt. or even smaller than that size. It is similar to pave setting but the stones are much smaller in micro-setting.
