Three stone rings, also known as trinity or trilogy rings, are associated with love and marriage. The symbolism of the rings may vary according to the wearer. Some may say that they wear three stone rings to represent their past, present and future with their beloved, while others associate a religious value to the jewels. They’re becoming increasingly popular for engagement and wedding bands.
The most popular style of three stone rings is three diamonds in a row of the same cut, with the center stone larger than the side jewels. Round brilliants are usually the cut of choice, though princess, oval and rectangular diamonds may also be used. Another variation on the three stone ring is to have the side jewels be a different cut from the central diamond, such as triangular stones flanking a princess cut.
