Bottom Line Recommendation:

Three-stone settings offer both personality and additional sparkle. With the ability to create an original design, a three-stone ring is a beautiful, unique choice. This Round Cut engagement ring, for example, is a timeless design, while this diamond and emerald ring is modern and colorful. 

No matter which style you choose, be sure to purchase your ring from a reputable vendor. Based on our experience in the industry, we recommend Blue Nile, James Allen and Brian Gavin Diamonds.

What is a Three-Stone Engagement Ring Setting?

Indicated by its name, three diamonds or gemstones are set closely together in this type of setting. The stones can be the same size or the center stone may be the largest. This three-stone setting uses colored stones for the side accents, while this ring incorporates baguette diamonds.

You can design three-stone settings with any type of precious metal: white gold, yellow gold, platinum or rose gold. You can also pair a three-stone design with another type of setting, like a pavé band or a channel setting. The numerous options available with three-stone rings make them a popular choice for engagements.

Why Choose a Three-Stone Engagement Ring?

The three-stone setting is a unique and versatile setting. The three stones, set closely together, are said to symbolize the couple’s past, present and future. Not only are you creating a ring that’s beautiful, but meaningful as well.

Many people choose a three-stone setting because they can personalize it.  You have the option to choose similar-sized diamonds, diamonds of different shapes and sizes, or colorful side stones like emeralds, rubies and other birthstones.

Three-Stone Settings For Every Shape

Three-stone settings can be created with any Diamond Shape, but work best with Round Brilliants, Radiant Cuts, Cushions, Princess Cuts and Emerald Cuts.

When designing a three-stone ring, it’s important that the stones compliment each other, rather than clash. The styles below can be used as inspiration for designing your own three-stone ring.

Pros and Cons of a Three-Stone Setting

A three-stone setting is a beautiful choice. There are, of course, advantages and disadvantages to every ring style. Review the pros and cons below to determine if a three-stone engagement ring is right for the one you love.


  • Offers a large amount of sparkle and brilliance
  • Allows for multiple larger stones (including ones of different colors)
  • Enhances the appearance of the center stone when paired properly with side stones
  • Can achieve a greater surface area of gemstone or diamonds than a singular setting
  • Gives options for personalizing the ring


  • Requires more cleaning and maintenance than a single stone design
  • When stones are poorly paired, the side stones can overpower or distract from the beauty of the center stone

Where to Buy Three-Stone Diamond Engagement Rings

Throughout our years in the industry, we’ve closely vetted diamond sellers to determine the best and most reliable in the business. Choosing where you’ll purchase your engagement ring is extremely important. Both brick and mortar stores and online vendors can overcharge you—all while offering you inferior beauty and value. We don’t want that to happen to you, or any of our readers.

We recommend looking for an engagement ring through the diamond dealers below. They are reputable and maintain high-quality collections of diamonds and settings. All diamonds come with an AGS or GIA certificate—allowing you to trust what they’re selling you. If you have any questions about these vendors, please email us.

Evaluating a Diamond Ring for Beauty and Value

At Diamond Pro, we want you to find the best diamond for the best price. We have an extensive collection of diamond educational resources to help you select the most beautiful ring for your budget.

  • Diamond Shape: Choose a shape based on your personal style and preference. Be sure to match your stone with a setting that offers safety and security.
  • Diamond Cut: More than any other quality, Cut plays the biggest role in a diamond’s beauty. Only consider Excellent and Ideal cut diamonds.
  • Diamond Color: To the naked eye, diamonds in the G to I Color range will appear colorless, but cost far less than diamonds in the D to F range. Be sure your diamond looks white in relation to its setting.
  • Diamond Clarity: Always choose a diamond that’s eye clean, but remember you don’t need a diamond that’s flawless under magnification. Inclusions and blemishes often cannot be seen with the naked eye at a VS1 or VS2 Clarity grade. While you can pay more for higher Clarity, it will likely go unnoticed.
