Pear Buying Guide
The pear shaped diamond, which has 58 facets, boasts a unique droplet-like silhouette that merges elegance with brilliance. While not the most traditional choice, its elongated shape can enhance the slender appearance of the fingers.
Cut
The ideal length-to-width ratio for pear-shaped diamonds is 1.5 to 1.6.
The ideal length-to-width ratio for pear-shaped diamonds is 1.5 to 1.6. Ratios that exceed this range may cause the pear shape to appear distorted, resembling a deformed marquise. Pear-shaped diamonds often display a bow-tie effect, which can vary from barely visible to quite pronounced; this effect cannot be determined from the diamond's certificate or dimensions and must be evaluated through visual inspection.
Additionally, some pear-shaped diamonds feature a keel line, where the culet is integrated into a line extending down the diamond's length where the pavilion facets meet. This keel line should be equidistant from both sides of the diamond, just like the culet.
Colour
Pear-shaped diamonds are among the shapes where colour is most apparent.
To ensure that your diamond appears white, we recommend a colour grade of D, E or F, particularly if the stone will be set in white gold or platinum.
In larger pear-shaped diamonds (over 1 carat), the colour may appear slightly darker at the point. Therefore, it may be advisable to select one colour grade higher than what is typically chosen for other diamond shapes.
Recommended · D to F
Clarity
For the best value, select diamonds with SI1 to VS2 clarity. Pear shapes, like round brilliant diamonds, are effective at concealing inclusions. This means you can often find an eye-clean diamond even within the lower clarity ranges.

What to look for in the stones below
The other thing these images show is the bow-tie — a dark contrast pattern affected by cut, lighting and viewing position, including light blocked by the observer. Some moving contrast is normal. Judge whether a dark band remains distracting as the stone moves, using clear video or an in-person view under more than one light source. Measurements alone cannot settle that judgement.
GoodBlended bow-tie, eye-clean, clean point
AvoidHeavy bow-tie, inclusions in the table or point
Pear diamond size chart
What a pear's measurements mean in carat weight. Every row from 0.30ct up is the median of real certified pears in our own inventory, with the sample size beside it; the smaller sizes come from our diamond supplier's book, because we don't stock loose stones that small and quoting inventory we don't have would be dishonest.

Rows from 0.30 ct up are the median of our own GIA and IGI certified stones, with the sample size shown and the typical range being the middle 80% of that bucket. Smaller sizes come from our diamond supplier's own book where it carries the shape, and are calculated from the trade weight formula where it does not. Covers 2.0 mm to 19.0 mm. Snapshot 2026-08-30.
Length and width give an indicative weight range. Depth, girdle thickness and other proportions also affect weight, so this table is an estimate. Use the individual grading report or a measured loose-stone weight for an exact figure. For every other shape, and a converter that works both ways, see the full diamond size chart.

Common questions
Which way does a pear cut point on the finger?
The convention is point-toward-the-fingertip — the taper leads the eye down the finger, enhancing the elongating effect. Some wearers prefer point-toward-the-hand for a more contemporary look. Both orientations are correct; the choice is aesthetic. The setting must be built accordingly since the metal supports differ between orientations.Do pear cuts show colour more than round?
Yes — the tapered point concentrates body colour more than a round brilliant does. On stones over 1.00 carat we recommend going one colour grade higher than you would for a round of the same size. D to F is where we aim for pear cuts, particularly in white gold and platinum, where any warmth in the stone shows against the metal.Which setting protects the tip of a pear cut?
A V-tip prong is essential — it wraps the point, protecting the diamond's most vulnerable corner from chips and knocks. Halo settings also work well, adding both physical protection and visual size. Avoid open bezels that expose the tip; the point needs metal contact to survive daily wear.Which finger shape suits a pear?
The pear shaped diamond elongates the finger, which flatters shorter fingers particularly well. The taper draws the eye along the length of the hand. For longer fingers, staying at the lower end of the 1.5 to 1.6 range preserves the pear character without stretching the visual too far.
