Often when people begin their hunt for a diamond engagement ring, they come across a common term, SOLITAIRE. And this makes them wonder, “What is a solitaire diamond”? So, without further ado, let’s know more about what a solitaire ring is. 

Diamond Solitaire Rings

A diamond solitaire is any jewellery that has only one diamond. Hence, a solitaire ring has a single diamond (or any gemstone) without any diamonds or pave diamonds on the ring band or the sides of the shank of the ring

Diamond Solitaire rings have symbolized engagements for many years. No matter what’s trending, their style stands strong. And why not? These are an epitome of classic beauty, simplicity and elegance that you won’t find in any other ring setting. 

What is the difference between solitaire and diamond?

There has always been a confusion when Jewellers use the terms, solitaire and diamond interchangeably. However, the two have distinct meanings. While the term ‘Solitaire’ refers to the gemstone setting, ‘diamond’ is a type of gemstone. Putting them together, diamond solitaire is a single diamond gemstone set into a ring (or earring, necklace). An interesting thing to note here is that a solitaire setting can have a diamond. But, not every diamond is a solitaire.

History of Solitaire Rings – What’s a solitaire ring

Solitaire diamond rings have been popular for as long as rings have existed.  Diamonds studded in plain gold bands were popular in Ancient Rome. The trend remained high until a boom in the 1940s made solitaire sales skyrocket. 

After the Great Depression and World War II, troubled diamond professionals decided to boost diamond sales in America. Since diamonds had been popular among the rich before, diamond producers began to produce smaller diamonds that they could sell to more people. 

In 1948, De Beers, who was the industry leader then, decided to boost diamond sales amongst the American middle classes. During this time, De Beers launched their marketing campaign with a 4 words slogan “A Diamond is Forever”. Soon, it started catching the eyes of people. Sales boomed and solitaire rings were an instant hit. And.. the rest is history!

Diamond Solitaire Rings Features

Let us take a look at what are the features that make diamond solitaires a desire of every fashionista and brides-to-be.

Diamond Size

It is a misconception that diamond in a solitaire engagement ring must be big to enhance its overall look. However, this is not the case. There are certain other considerations that make your centre stone look big adding to the overall look of your solitaire ring. This brings us to our next characteristic -brand size.

Band Size

A smaller diamond paired with a thinner band makes the diamond appear big. Further, to add intricacy and depth, one can use a two-toned or etched band. This solitaire ring design will draw attention to the ring as a whole rather than just the gemstone or diamond. 


Solitaire rings aren’t just made in round shape.  Although, it is the most preferred shape among the ring buyers. There are many other diamond shapes that can create a beautiful solitaire ring with just a single stone. For instance, 

  • Emerald, oval-shaped, pear, and marquise-shaped stones elongate the central diamond making it appear larger than it actually is.
  • A trillium-shaped or heart-shaped stone is eye-catching because of its uniqueness. It highlights the shape by minimizing the stone’s size.


To add elegance and beauty to the diamond solitaire ring, you can create a two-tone ring. Besides, you can also use a higher-quality metal than the standard 14-karat gold. It will emphasize the band as a part of the ring just like the stone. Thus, you can choose: 

  • Higher grades of gold, such as 18K.
  • White gold and platinum – for a monochromatic look. 
  • Copper or brass for two-toned rings 
  • Rose gold

It is one of the most famous solitaire ring settings. As the name suggests, the famous Tiffany & Co are the designers of this setting. It uses a special six-prong design, which increases the amount of light reaching the centre diamond. The Tiffany setting uses a knife-edge along with the six thin prongs, which expose the diamond giving it the brightest possible sparkle. However, Tiffany & Co. have trademarked the original prong design. This means that the only place you can buy a “Tiffany” solitaire ring is from one of their stores.  

Four and Six-Prong Solitaire Settings

The centre diamond remains at the place because of several small prongs. These prongs extend out from the ring band. 


When it comes to buying a solitaire ring, one looks for a ring that matches the style of your significant other. You consider their lifestyle and that the diamond is relatively easy to maintain while buying a solitaire ring. To make your job easier, here we have listed the pros and cons of a solitaire setting you must consider before making your final decision.


  • Having a single diamond in the centre makes the ring more noticeable.
  • The solitaire setting allows a significant amount of light to pass through the centre stone. This, in turn, increases its fire and brilliance. 
  • A solitaire setting complements a variety of diamond shapes and sizes.
  • Provides a classic, timeless look.
  • These are usually easy to clean and maintain. 


  • Diamonds in a solitaire setting can snag on clothing, furniture, and other materials, particularly if the diamond is set high. Hence, we suggest buying a lower-set prong for the wearer with an active lifestyle.
  • Though not often, prongs in this setting may loosen over time. Hence, we suggest you get the prongs inspected every two years (at least) to ensure diamond safety.
