Short answer
Choose pear if you want an elongated shape with a clear direction and are prepared to inspect symmetry, bow tie and point protection.
The look
A pear can be worn point-up, point-down or across the finger. Orientation is personal. What matters is that the shoulders flow into the point without one side looking heavier than the other.
Use the measurements
Length-to-width ratios around 1.50 to 1.75 are commonly preferred, but the outline matters more than hitting a number. Use actual length and width for size comparison.
What to inspect on the exact diamond
- Draw an imaginary line from the point through the centre. Both sides should mirror each other.
- Check for flat or overly broad shoulders and an off-centre point.
- Watch for a dark bow tie that remains distracting as the diamond moves.
- Look for inclusions near the point and confirm how the setting protects it.
Plan the setting at the same time
The point needs deliberate protection, often with a V-shaped prong or enclosing bezel. Check that the setting does not pull the diamond visually to one side.
If this shape is not quite right
Choose oval for two rounded ends, marquise for two pointed ends, or round for the most symmetrical and standardised outline.
