STORIES - The History and Meaning of the Solitaire Ring

One stone, one setting, nothing more. The solitaire ring is, in many ways, the simplest form a ring can take and yet it has become the most recognised symbol of commitment in the world. In this blog, we look at where the solitaire ring came from, and how it grew into the design we know today.

What makes a ring a "solitaire"?

The term solitaire refers to a ring featuring a single gemstone, almost always a diamond, set on its own without accompanying stones. The word comes from the French solitaire, meaning "solitary" or "alone." The design draws its power from restraint: without smaller stones to share the attention, the single gem becomes the entire focus of the piece.

Early origins

Rings set with a single stone have existed for centuries, but they weren't always associated with engagements. In ancient Rome, rings were exchanged as a symbol of ownership and intent to marry, though these were typically simple bands, often made of iron, without stones at all. The idea of marking a proposal with a ring featuring a gemstone developed gradually over time, largely among European nobility, where elaborate cluster settings (many small stones grouped together) were the fashion for centuries.

The shift to a single, prominent stone

The solitaire as we recognise it today began to take shape in the late 19th century. A key turning point came with the development of the six-prong setting, patented by Tiffany & Co. in 1886. Known as the "Tiffany Setting," it lifted the diamond above the band on six delicate claws, exposing more of the stone to light than earlier bezel or cluster settings allowed. This wasn't just an aesthetic choice, it was engineering in service of brilliance, letting light enter the diamond from more angles and maximising its sparkle.

This innovation shifted the emphasis away from elaborate settings and toward the stone itself. A single, well-cut diamond, given room to catch the light, no longer needed smaller stones around it to make an impression.

Why the solitaire became the engagement ring

Several things reinforced the solitaire's position as the definitive engagement ring through the 20th century:

• Diamond mining expansion — the discovery of major diamond deposits, particularly in South Africa in the late 1800s, made diamonds significantly more available than before
• Marketing — a well-known 20th-century De Beers campaign linked diamonds directly to engagements and lasting love, cementing the diamond solitaire as the expected choice
• Design philosophy — as jewellery design moved through the Art Deco period and beyond, the clean lines of a single stone suited changing tastes toward simplicity and clarity

By the mid-20th century, the diamond solitaire had become the default engagement ring across much of the Western world, a position it still holds today.

What the solitaire represents

Beyond its history, the solitaire carries meaning in its very simplicity. A single stone, undivided and unaccompanied, is often read as a symbol of a singular, undivided commitment; one person, one promise. Its minimalism also gives it a certain timelessness: unlike more elaborate or trend-driven designs, a well-proportioned solitaire rarely looks dated, which is part of why it remains such an enduring choice generations later.

A design that still evolves

While the classic round brilliant solitaire remains iconic, the style has continued to develop. Today's solitaires appear in a wide range of cut shapes (oval, emerald, pear, cushion) and settings, from the original raised prongs to sleeker, low-profile designs. What hasn't changed is the core idea first refined over a century ago: one stone, given the space to speak for itself.
