Pear-Shaped Diamond Ratios: Choosing the Perfect Proportions

The pear-shaped diamond is instantly recognisable for its teardrop silhouette - rounded at one end, pointed at the other - and its proportions have a huge impact on how the stone looks and sparkles. The right ratio can make the diamond appear more balanced, elongated, or chunky & bold, so understanding these subtle differences is key when choosing the perfect pear.

Pear Shape Ratios in Practice

A diamond ratio is the length in millimetres divided by the diamond’s width in millimetres.

 

 

Fatter Pear (lower ratio, ~1.40 – 1.50):
Broader body, more width through the center, giving them a fuller, chunkier look.

Balanced Pear (sweet spot, ~1.55 – 1.65):
That classic teardrop shape without looking overly wide or too elongated.

Skinnier Pear (higher ratio, ~1.70 – 1.80+):
Longer and narrower, creating an elegant, elongated teardrop effect. Watch out for more prominent bow-ties* though!

*Bow-tie effect: all pear shaped diamonds will have some bow-tie (a darker area across centre), but you want one that’s minimal and doesn’t detract from sparkle. Always view images/videos from different angles and light.


Other Proportion & Practical Considerations

1. The girdle thickness matters: too thin, especially near the tip, and the stone is more fragile; too thick can make it look dull or reduce light performance. 

2. Tip protection: because the point is vulnerable, settings that use a V-prong or extra prong there, or even partial/bezel protection, are highly recommended. 

3. Colour visibility: The tip and narrow parts of a pear often show colour more noticeably than broader parts; you may want to choose a slightly better color grade (or a setting metal that enhances the look) to compensate.
