What Is A Trilogy Engagement Ring?

At Diamond Heaven, we’ll guide you through everything you need to know, from the meanings behind the three-stone design to the customisation options that make each ring uniquely yours. Plus, explore our handpicked selection of standout trilogy rings to find the perfect three-stone ring.

What is a Trilogy Engagement Ring?

Trilogy rings consist of three stones set into a ring, and are also referred to as three stone rings. This type of diamond ring is extremely versatile, as trilogy rings can be used not just as an engagement ring but also as an eternity ring, anniversary ring or push present. 

There are many different styles of trilogy rings. For example, you could have a trilogy engagement ring with all round cut equal-sized diamonds or two smaller side stones with a larger center stone. You can choose a trilogy ring with diamonds or gemstones and choose which one is the perfect centerpiece for your ring. The centre stone of a trilogy ring can be a completely different shape to the side stones. It can be an elongated shape such as an oval, pear, radiant or emerald cut, these are all very popular shapes in trilogy rings on the market today. 

What does a Trilogy Ring mean?

Traditionally, these stones represent your past, present and future together, making trilogy rings a deeply meaningful choice for engagement rings. Alternatively, you may choose a trilogy ring to tell your unique family story as they are popular push presents. For example, the three stones may represent you both and your first born child creating the start of your family and future together. It can also represent having three children together, or the central gem might honour a mother, with the side stones representing two children. These are just a few of the personal, family-focused meanings you can express with a three-stone design.

Why Shape and Cut Matter When Customising your Trilogy Ring

Choosing the right shape and cut for a trilogy ring directly influences both the ring’s overall look and how it interacts with light. Here’s how to customise your trilogy ring taking the shape and cut into account for the right combination and sparkle. 

The best way to start customising your trilogy ring is to consider the center stone first. The center stone can give a traditional look to your ring or a more modern twist depending on the shape and if you choose a diamond or gemstone center. Once you have made your decision you can search all trilogy designs with this center and find the ring with side stones that complement that shape the most. Once you have found your favourite designs it is time to visit the jewellers and try them all on as each shape and combination can give a different look on the hand. This will help you narrow it down to your final choice and help you customise the carat weight. Choosing the perfect carat weight is key to getting the ring right as you want it to complement your hand, every day routine and still make a bold statement, especially if it's an engagement ring. You can tailor the total carat weight of the ring all the way up to 5.00ct in most of our designs in natural and lab grown diamond.

We still recommend viewing the rings in person if you are shopping without your partner and planning the big surprise as this can help you choose the right design confidently, whilst getting all questions answered about the diamond. 

Once you have the shape, the ring design and the perfect carat weight, you are ready to start looking at the quality differences in the diamond or gemstone. Our experts can help you choose between a natural or lab-grown diamond and take you through the colour and clarity diamond grades and select your preferred diamond colour (G-H are near-colourless or D-F for a bright, colourless diamond) and clarity grades (from SI2 up to IF) see the price difference each step of the way for more sparkle and choose what is right for you. 

Then the final stage is deciding on the cut grade, which determines how well the diamond was cut to reflect light. This is based on the diamond's dimensions and facet angles/arrangement, this grade will affect how much fire and brilliance your diamond has. Depending on your budget we recommend an Ideal, Excellent or Very Good grade, compare the price differences as this is the final stage of customising your diamond and the higher you go the sparklier the diamond will be. If you have selected a gemstone our experts will take you through the different options and compare different stones so that you get the perfect colour and quality in your gemstone trilogy ring. 

Once you have finished your trilogy ring diamond customisation, you can choose from our in-house Diamond Heaven certificate or upgrade your diamond to an IGI or GIA certified center stone. We offer a wide selection of loose GIA and IGI certified diamonds instore and online and our Experts in store or on live chat can help you each step of the way in your customisation process.
