History of the three stone engagement ring

Despite its classic aesthetic, the three-stone engagement ring is a modern design that is just over 20 years old. 

In the early 2000s, a highly popular marketing campaign for the then-new three-stone ring captured the public imagination with the phrase “Past, Present, and Future”.

The popularity of the three-stone ring has continued to the present day because of the simplicity of the design and its ability to convey multiple meanings. 

This means that the ring can convey a wonderful, lasting sentiment for couples who want to communicate their friendship, love, and fidelity.

Prince Harry’s selection of a custom three-stone engagement ring for his wife, Meghan Markle in 2017 further increased interest and demand for this refined design. 

What to look for in a three-stone engagement ring

Three-stone rings do not have to do much to attract admirers. This iconic design endures, in part, because of these three features:


The proportional relationship between the three individual stones is key to the beauty of a three-stone ring. 

These rings either have a large center stone and smaller side stones or three stones of equivalent size and weight

Desirable size ratios between the center stone and accent stones are entirely the prerogative of the wearer but accent stones that are a third or half the size of the center stone are most pleasing. 


Like a solitaire, the quality of the diamonds imparts the elegance and exclusivity of a three-stone engagement ring. Select the very best stones your money can buy according to color, cut, clarity, and carat weight. The cut is especially important for bringing out the fire and brilliance that makes the three-stone ring so captivating. 

An understated setting

A simple band adds to the refinement of the three-stone ring. A band with a width of under 2 mm allows the stones to speak for themselves and wears elegantly alongside a wedding band or eternity ring. 

Diamond combinations in three-stone engagement rings

Make this engagement ring your own by choosing from a variety of center and accent stones. Asscher, marquise, oval, or cushion-cut diamonds are equally stunning alternatives to the classic prong-set round brilliant diamond.

Options for the paired accent stones that are set either side of the center stones include:

Round brilliant

Trillion diamonds are triangular side stones. This unusual cut has a large table width that makes these diamonds appear larger than their carat size. Trillion diamonds make a distinctive choice and enhance any center stone, following the natural curve of the engagement ring.

Beautiful enhancement of the center stone

Expert jewelers select side stones that enhance the beauty of the center stone. This nuanced grouping is carefully balanced for cut, color, clarity, and carats so that the accent stones do not overwhelm the center stone.

The three-stone ring is not a traditional engagement ring

Did you know that the three-stone ring design was not originally an engagement ring? The strong symbolism and popularity of this ring meant that it became widely adopted as one. Depending on your personal taste, you may prefer a classic solitaire.

Three stone rings require more maintenance
