Trilogy Engagement Rings

Sometimes referred to as ‘trinity rings’, trilogy rings are set with three gems, a configuration that is said to represent your past, present and future. This seemingly simple design can be configured many different ways, so here are some key decisions you may wish to consider if you think a trilogy engagement ring might be the right choice.

Consider Combining Diamonds And Coloured Gemstones

Many trilogy designs consist of three diamonds, and this is the most popular arrangement. However, it’s not at all unusual to combine diamonds with a coloured gemstone, usually ruby, sapphire or emerald. If a coloured stone is involved, it is usually the centrepiece, flanked by two diamonds, but it is not unusual to reverse this arrangement, with a diamond set between a matching pair of coloured gems. However as diamonds are typically priced higher than coloured gemstones, using a diamond as the centrepiece may well end up being a more expensive option.

Consider Combining Different Cuts












Once you’ve decided on what combination of gems to use, you’ll need to think about your preferred shapes. Aesthetically, designs tend to work best if you combine straight-edged shapes with other straight-edged shapes, while rounded or ‘soft’ shapes work well with other ‘soft’ shapes. For example, a rectangular or emerald cut central stone can look fantastic flanked by two smaller emerald cuts or straight baguette cuts, while a central oval gemstone will often be flanked by two smaller round stones. Certain shapes seem to naturally work well as ‘accent’ stones, offering great versatility – pear cuts (sometimes referred to as tear drops) and tapered baguettes can all look good alongside almost any central gemstone, whether rounded or straight edged.

Two Trilogy Rings

Consider the size of the centre stone versus the side stones You’ll need to think about the relative sizes of the centrepiece and the two accent stones. The two side stones together will often weigh roughly the same as the centre stone – for example, a central half carat diamond might be flanked by two quarter carat diamonds. However, this is just a rule of thumb, and it is possible to create a really distinctive design using either a more even balance between the three stones, or alternatively using a more dominant central stone.

Consider The Overall Design Aesthetic

Depending on your preferred combination of shapes, you may lean either towards a more traditional or a more contemporary look. Three round diamonds is a very traditional configuration, whereas three emerald cuts stones is a combination associated more with the Art Deco era. This will be reinforced by your choice of setting style – traditional rings are often set with claws, while swirl or rub-over settings can create a more contemporary look.
