The three-stone setting, also referred to as the trilogy setting, is a versatile setting that can be chosen for engagement, anniversary, or any occasion rings. It is popular amongst those that like to attribute meaning, be it religious, romantic or personal. For example, the three stones can represent the Father, the Son, and the Holy Ghost. Or the past, present, and the future. Another example, in the case of a first-born child, it can represent the baby and the parents. However you choose to interpret this setting, it can hold beautiful meaning.
The stones can either be all the same size or, as is often the case, the centre stone larger than the two side stones. The most popular diamond shapes for this setting are the round brilliant and the princess cut. However, various gemstones, such as emeralds, rubies, and sapphires, or other birthstones, make for a good addition of colour. A popular choice is a diamond in the centre and two blue sapphires either side.
