Why Diamond Shape Matters
Diamond shape impacts:
- How large the diamond appears
- How much it sparkles
- The overall style of the ring
- How it looks on your finger
Some shapes appear bigger, some sparkle more, and others feel more unique.
This is why choosing the right shape matters just as much as the diamond itself.
Your diamond shape also plays a big role in how much your ring costs — something we break down in our guide on how much to spend on an engagement ring in Toronto.

Which Diamond Shape Sparkles the Most?
If sparkle is your priority:

- Oval diamonds = strong sparkle + size

A well-cut diamond matters more than shape alone.
How to Choose the Right Shape for You
Choosing a diamond shape comes down to personal preference.
Ask yourself:
- Do you want something classic or unique?
- Do you prefer maximum sparkle or a softer look?
- Do you want the diamond to appear larger?
- What style does your partner typically wear?
Once you’ve narrowed down your preferred shape, the next step is choosing the right diamond — including deciding between lab-grown and natural diamonds.
