Classic Diamond Jewellery:
The Three Stone ring

After the royal engagement of Meghan Markle and Prince Harry, Meghan Markle’s engagement ring has been a source of inspiration to couples looking for the perfect ring to celebrate their union. 

Meghan Markle Three Stone Engagement Ring

The three stone engagement ring presented to Meghan by Prince Harry is comprised of one centre stone from Botswana and two from Princess Diana’s personal collection. With its winning combination of tradition and newness, as well as the embodiment of the royal couple’s unique love story, the three stone engagement ring is a much-loved classic piece of diamond jewellery.

What is a three stone ring?

Three stone diamond rings, also known as trinity rings or trilogy rings, are rings with three diamonds set horizontally in a row. Popular as both engagement rings and anniversary rings, there are several different styles of three stone diamond rings to choose from. 

History of the three stone ring

Although the three stone ring has long been a staple piece of jewellery, it was the launch in 2001 of the Trilogy campaign by De Beers that transformed the three stone diamond ring into a true icon. Depicted as the “Past, Present, and Future Ring”, the ring is rich in romantic symbolism.

What do the three stones symbolise?

The three stones tell a story of romance, commitment and the passing of time. The first diamond represents a couple’s past, when and how they met as well as their shared memories. The centre diamond symbolises the couple’s present together, whilst the third diamond reminds them of their future and the milestones still to come.

Choosing a three stone engagement ring versus a solitaire engagement ring

A diamond solitaire ring, another classic piece of diamond jewellery, is timeless, versatile and practical for day-to-day wear. It is also a very popular engagement ring and a wonderful choice for those looking for a more classic option.

However, with three stunning diamonds, trilogy rings are a sensational way to express the wearer’s unique personality through the choice of shape, size and setting etc. These really are statement rings.

Selecting your three stone diamond ring

There are many different elements you may want to consider before selecting your perfect three stone ring.


In order to enhance their continuity, it is traditional for all three diamonds to have the same shape. Popular shapes include round, square and emerald because they sit well together. The cushion-shaped central diamond of Meghan Markle’s ring is certain to inspire a trend for rings that feature this striking shape.


The traditional graduated trilogy ring features a larger central diamond whose carat weight is equal to the total of the two diamonds that are either side of it.

If you are looking for a more contemporary and unique ring choice, you may want to consider a three stone ring where the three diamonds are of identical size and carat weight – either set in a line or a less formal cluster arrangement.


Whether you opt for a prong or bezel setting, all three diamonds should be mounted in the same type of setting to emphasize their connection.


Gold, yellow gold, white gold and platinum are all popular metal choices for three diamond rings. Since the three diamonds comprise a significant portion of any trilogy ring, avoid mixed metal colours which might distract from the diamonds’ beauty.


As these rings already feature three spectacular diamonds, care should be taken when choosing a ring that features additional details. Be sure to select details that enhance your ring. A halo of smaller diamonds, or a line of pavé diamonds along the shank, are both excellent choices.

Styling your three stone ring

Since trilogy rings often feature a slightly curved silhouette they pair beautifully with a wedding band. They also make a great foundation around which to build a stacked look which could include other treasured rings such as a plain band, eternity band or a chic solitaire.

When pairing with other rings, avoid inadvertently scratching them by ensuring the diamonds on your trilogy ring don’t extend far beyond the band’s edges.

The past, present and future ring

Symbolising your past, present and future, a three stone diamond ring represents your commitment, devotion and dedication whether it’s to a loved one or to yourself. A romantic and classic piece of diamond jewellery, a three stone ring will be cherished Forever.
