Three Stone Lab Diamond Engagement Rings

A three stone lab diamond ring is a type of ring that features three main gemstones, typically diamonds, arranged in a row. The three gems in a three stone lab diamond ring can be of equal size or have a larger centre stone with two smaller stones on either side. This style is very often used as an engagement ring when the centre diamond is larger than the flanked side stones or as a right hand ring or eternity ring if the stones are all the same size. Three characteristics of three stone, also known as trilogy engagement rings are:

1. Symbolism: The three stones in a three stone ring are often said to represent the past, present, and future of a couple's relationship. Each stone carries its own meaning and significance, creating a sentimental message within the design.

2. Design versatility: Three stone rings offer a wide range of design possibilities. The gemstones can be of the same size or different sizes, and they can be set in various configurations such as prong, bezel, or channel settings. Additionally, the stones can be diamonds or other gemstones like sapphires or emeralds, allowing for personalisation and customisation.

3. Enhanced brilliance: The presence of multiple gemstones in a three stone ring enhances its overall sparkle and brilliance. The combination of three stones creates a captivating focal point, drawing attention and adding glamour to the ring. The extra gemstones can also make the centre stone appear larger and more prominent.

Amongst a few examples of celebrities who have chosen to wear trilogy diamond rings as an expression of their commitment and love include Jennifer Aniston, Meghan Markle and Reese Witherspoon.

Frequently Asked Questions

What is the history of the three stone diamond ring? 

The history of trilogy diamond rings can be traced back to ancient times when the concept of using gemstones to symbolise different aspects of a relationship was prevalent. However, the modern trilogy diamond ring as we know it today gained popularity in the late 19th and early 20th centuries.

During the Victorian era, sentimentality and symbolism became important in jewellery design. A three stone ring symbolised the sentiment of "yesterday, today, and tomorrow" or "I love you" and was often given as an engagement or anniversary ring. These rings were often adorned with diamonds, which represented durability and everlasting love.

In the 20th century, trilogy diamond rings gained further popularity, particularly during the Art Deco era. With the rise of industrialisation and mass production, diamond jewellery became more accessible and desirable. The clean lines, geometric shapes, and symmetry of the Art Deco style suited the trilogy diamond ring design, making it a popular choice for those seeking a unique and glamorous engagement ring.

Today, trilogy or three stone diamond rings continue to be a popular choice for engagement rings, offering a meaningful and sentimental symbol of love and commitment. They can be found in a variety of designs and settings, allowing individuals to choose a style that suits their personal taste and preferences.

Is a trilogy ring a good engagement ring?

As the three stones in a trilogy ring can symbolise the past, present, and future of a couple's relationship, it can add a meaningful sentiment when gifted as an engagement ring. This symbolism can make the ring even more special and significant.

Additionally, a trilogy ring offers a unique and eye-catching design. The arrangement of the stones in a row or with the larger centre stone slightly elevated can create a visually interesting and balanced look. The stones can be diamonds or other gemstones, allowing for personalisation and the inclusion of birthstones or favourite gemstones.

From a practical standpoint, a trilogy ring can offer more sparkle and brilliance compared to a single stone ring. The presence of multiple stones can enhance the overall appearance and make the ring stand out. The side stones can also make the centre stone appear larger and more prominent.

Ultimately, the choice of an engagement ring is a personal one and should reflect the individual's taste and style. If a trilogy ring holds sentimental value and resonates with the couple, it can make a beautiful and meaningful engagement ring.

Are there any disadvantages of choosing a trilogy diamond ring?

While a trilogy ring can be a beautiful choice for an engagement ring, there are a few risks or considerations to keep in mind:

Ring Size: The addition of multiple stones in a trilogy ring can sometimes make the ring feel bulkier or wider on the finger. This may not be a suitable choice for individuals with smaller hands or those who prefer a more delicate and streamlined look.

Maintenance: The setting of a trilogy ring can require additional maintenance compared to a solitaire ring. With multiple stones, there is a higher chance of them becoming loose or damaged over time especially if the prongs are exposed. Regular inspection and maintenance is recommended to ensure the stones are secure. Ethica offers a not for profit - link - [Ring Maintenance Service] helping you keep your halo diamond ring in perfect condition.  

Cost: Depending on the size and quality of the chosen stones, a trilogy ring may be more expensive compared to a solitaire ring with a single larger stone. The cost of three stones and the additional craftsmanship involved in setting them may increase the overall price.

Design Consistency: Finding three stones that match in terms of quality, colour, and size can sometimes be challenging. At Ethica, we make this process very easy for you as we carefully select the flanked stones that are a matching pair and a centre stone that is of a similar colour and clarity if you are choosing the same gemstones or diamonds.  However, it can be a little more tricky especially if you wanted coloured gemstones or fancy diamonds on the sides. Simply put, as there are more options and possibilities, there are more decisions to make!
