Choosing the perfect diamond shape is one of the most exciting — and sometimes overwhelming — parts of buying an engagement ring. Among the most popular options in Canada and the USA are Oval Diamond Engagement Rings and Round Diamond Engagement Rings. Both shapes offer unique beauty, sparkle, and style, but understanding their differences can help you choose the ring that perfectly reflects your personality and love story. 

Why Shape Matters in a Diamond

The shape of a diamond affects more than just its appearance. It influences:

  • Brilliance: How much the diamond sparkles.
  • Perceived size: Some shapes appear larger than others at the same carat weight.
  • Style compatibility: Certain shapes pair better with specific ring settings.
  • Finger appearance: Elongated shapes can create a slimming effect.

For couples in Canada and the USA, selecting between Oval Diamond Engagement Ring designs and Round Diamond Engagement Ring designs often comes down to a mix of sparkle preference, style, and practicality. 

Round Diamond Engagement Rings: Classic and Brilliant

Round diamonds are the most popular diamond shape worldwide and have remained a top choice for engagement rings for over a century.

Why choose a round diamond?

  • Maximum brilliance: With 58 expertly cut facets, round diamonds reflect light exceptionally well.
  • Timeless style: Perfect for solitaire, halo, pavĂ©, or vintage settings.
  • Versatile design: Fits all finger sizes and works with almost any band style.
  • Proven popularity: More than 70% of engagement rings in North America feature round diamonds.

đź’ˇ Tip: Round diamonds are ideal if you want a classic, sparkling look that never goes out of style. 

Oval Diamond Engagement Rings: Elegant and Elongating

Oval diamonds are a variation of the round brilliant cut, shaped into an elongated oval. This shape combines elegance with modern appeal, offering a unique twist on traditional engagement rings.

Why choose an oval diamond?

  • Illusion of size: Oval diamonds appear larger than round diamonds of the same carat weight.
  • Elongating effect: The elongated shape can make fingers look longer and slimmer.
  • Modern elegance: Offers a distinctive look while maintaining classic brilliance.
  • Versatile settings: Works beautifully with solitaire, halo, and side-stone designs.

đź’Ž Fun fact: Oval diamonds have a “bow-tie effect” — a subtle dark area across the center — which adds character when cut correctly.
