We all know how unique each stone can be, but the way your stone is set is just as important in terms of showing off it’s good qualities as the stone itself. Do you want a light, flashy look or a heavier, more durable look?
The prong setting is the most common way to set a stone. It has tips that bend around the diamond to closely hold it in place. The most common prong mountings contain 4 prongs, but the popular martini mountings for stud earrings contain only 3 prongs.
It should take no one by surprise that the more prongs there are holding in a stone, the more secure that stone will be. Using too many prongs however, could potentially obstruct the view of the gem or the overall design of the piece.
When a stone is channel set, the edge of the stone is placed in a slit on the band which holds the stone in place. A channel setting is much more commonly used for bands and accent stones, rather than holding in a center stone. The stones in a channel setting are very secure, but their brilliance is slightly less than maximized because they are set partially beneath the metal.
In a bezel setting, the stone is wrapped in a ring of metal which holds the stone in place. This is a very secure way to set a stone, but it is a dangerous route to go with soft stones, because they are more at risk of breaking during this type of setting due to the pressure needed to tighten the bezel. This is the reason you will rarely or never see bezel set opals or pearls.
A tension setting will allow your stone to be showcased fully, because it will not cover up the sides or bottom of the stone at all. Two pieces of metal would press against the stone at the girdle to hold it in place.
This type of setting is good for showing off your stone, but it is more dangerous because if one of the two pieces of metal holding in the stone gets bent, then your stone could potentially fall out and become lost. Sizing is also complicated on rings with this type of setting because the head needs to be reworked during this process to maintain the tight grip on the stone.
A pavé setting incorporates multiple, very visible gemstones held in place by tiny, virtually invisible prongs that circle the ring. This type of setting is very popular for the accent stones in engagement rings. A pavé set fashion ring is also a popular option for making a loud statement without the need to pay for a large stone.
