The pear cut is one of the most expressive shapes in fine jewellery. Sometimes called the teardrop, it pairs the rounded brilliance of a round cut at one end with a tapered point at the other, giving a single stone both softness and direction. That same individuality is what makes the pear worth understanding before you choose one. Two pears of identical carat weight and clarity can look quite different in the hand, and the difference almost always comes down to proportion, symmetry, and how light moves through the stone. This guide walks through what to look for in a pear cut lab-grown diamond, with particular attention to the bowtie, the length-to-width ratio, the symmetry of the point and shoulders, and the curve of the wings. Each of these is a practical, observable thing you can assess for yourself.
Why the Pear Cut Rewards a Closer Look
Round brilliant diamonds are cut to a tightly defined formula, which makes them easy to compare. Fancy shapes such as the pear are graded on more open criteria, so cut quality varies far more from stone to stone. This is not a drawback. It means a well-chosen pear can show real character and brilliance, but it also means the buyer benefits from knowing what separates a considered cut from an average one. Because every lab-grown diamond we offer is independently certified by IGI, GIA, or an equivalent laboratory, you have a documented reference point for clarity, colour, and carat. The certificate tells you a great amount, but the visual qualities discussed below are best judged with your own eye alongside the report.
It also helps to remember that the pear belongs to the family of brilliant cuts, sharing its faceting logic with the round and the oval. That faceting is what gives a well-cut pear its lively return of light, and it is also what produces the bowtie. Understanding the four qualities that follow, the bowtie, the ratio, the symmetry, and the wings, gives you a practical framework you can apply to any pear you are considering, whether you are choosing a centre stone for a ring or a stone for a pendant.
Understanding the Bowtie
The bowtie is the single most asked-about feature of the pear cut, and it is the reason the query "pear cut lab grown diamond bowtie" comes up so often. A bowtie is a darker shadow that runs across the centre of the stone, roughly perpendicular to its length, resembling a bow tie or a propeller. It appears because light entering that part of the diamond is reflected back towards the viewer rather than returned as brilliance, leaving a dim zone.
Almost every pear cut diamond has some degree of bowtie. It is a natural consequence of the shape and the way its facets are arranged. The question is never whether a bowtie exists, but how pronounced it is. A faint bowtie that shifts and disappears as the stone moves is considered normal and is rarely a concern. A heavy, fixed bowtie that reads as a solid black band across the centre will dull the stone and draw the eye away from its brilliance.
How to Assess a Bowtie
- View the stone face-up in even, indirect lighting rather than a single bright spotlight, which can exaggerate or hide the effect.
- Tilt and rock the diamond gently. A mild bowtie will flicker and break up with movement, while a severe one stays dark and static.
- Compare the centre to the wings. The body of the stone should still return light around the shadow. If the centre is consistently lifeless, the cut is working against you.
- Trust your eye over the grade. Bowtie severity is not captured by a single number on a certificate, so a visual review, or clear imagery, matters here.
Because bowtie intensity comes down to cut proportions rather than the material itself, it is something to evaluate on each individual stone. This is where viewing high-quality images or video, or asking us directly, is worthwhile.
Length-to-Width Ratio
The length-to-width ratio describes the outline of the pear, measured by dividing the length of the stone by its width. It is the clearest lever you have for choosing the silhouette you prefer, and it is a matter of taste rather than right or wrong.
- Around 1.45 to 1.55 is widely regarded as the classic, balanced pear outline. It reads as a recognisable teardrop without looking either stubby or stretched.
- Below about 1.45 gives a rounder, fuller shape. These pears can look larger across the finger and feel softer.
- Above about 1.55 produces a longer, more elongated pear. The slender outline can flatter the hand and create a sense of length on the finger.
None of these is more correct than the others. A longer ratio suits someone drawn to an elegant, drawn-out line, while a fuller ratio appeals to those who want the shape to read as broad and generous. The key is to choose the ratio deliberately rather than by accident, and to view the stone as a whole rather than relying on the number alone.
Symmetry of the Point and Shoulders
A pear has one rounded end and one tapered point, joined by two curved sides. Symmetry is what holds this asymmetric shape together and makes it look intentional and refined.
The Point
The point should sit precisely on the central axis of the stone, in line with the apex of the rounded end. Draw an imaginary line down the middle of the diamond, from the tip of the point to the centre of the curved end. The two halves on either side of that line should mirror each other. A point that leans even slightly to one side gives the whole stone a tilted, off-balance appearance that is hard to ignore once noticed.
The point is also the most vulnerable part of a pear. In a finished piece it should be protected by a setting, most often a V-shaped prong that cradles the tip and guards it from knocks. This is a practical consideration to raise when the stone is being set.
The Shoulders
The shoulders are the rounded sections at the wider end, where the curve turns back towards the point. Well-cut shoulders are even and gently rounded on both sides. If one shoulder is higher, flatter, or more sharply curved than the other, the stone looks lopsided. Hold the diamond with the point facing away from you and check that the two shoulders are balanced as a matched pair.
Wing Curvature
The wings are the two long, curved sides that run from the shoulders down to the point. Their shape has a large effect on whether a pear looks graceful or awkward, yet wings are easy to overlook because there is no single grade for them.
- Even, gradual curves on both wings give the classic, flowing teardrop. The curve should ease smoothly from the widest part of the shoulder towards the point.
- Wings that are too flat create a shape that can look narrow and tense, sometimes described as resembling a marquise rather than a true pear.
- Wings that bulge too much push the widest part of the stone outward and can give a heavy, rounded look that loses the elegance of the taper.
As with the shoulders, the two wings should mirror each other. A stone where one wing curves more than the other will sit unevenly in a setting and on the finger. Viewing the outline of the pear on a plain background, with nothing distracting around it, is the simplest way to read the wings honestly. A short tip is to look at the pear in silhouette, ignoring the facets for a moment, and ask whether the outline alone would read as a balanced, flowing teardrop. If the shape feels right before you study the brilliance, the wings and shoulders are most likely doing their job.
How to Wear a Pear Cut
One of the qualities that makes the pear distinctive is that it has direction, and how you orient it is part of how you wear it. There is no single rule, only conventions and personal preference.
- Point towards the fingertip is the most common orientation in rings. Many find that it lengthens the appearance of the finger and gives a slimming line to the hand.
- Point towards the wrist is a deliberate alternative chosen by some wearers, and it is entirely valid. The orientation is set when the ring is made.
- Pendants and drop earrings traditionally hang with the point downward, which is where the teardrop association is strongest. The pear is a natural fit for these pieces because the shape leads the eye along its length.
Because the point is the most exposed corner, day-to-day wear benefits from a protective setting and a moment of care around hard surfaces. A pear set with a V-prong at the tip is well suited to everyday rings, while pendants and earrings face fewer knocks by their nature.

Bringing It Together
Choosing a pear cut lab-grown diamond comes down to a short, repeatable checklist. Look at the bowtie under even light and judge whether it flickers or sits as a fixed shadow. Decide on a length-to-width ratio that suits the silhouette you want. Confirm the point sits on the central axis and the shoulders are an even pair. Check that the two wings curve smoothly and mirror each other. Then consider how the stone will be worn and set, with attention to protecting the point. Each lab-grown diamond we source is independently certified and held to a minimum clarity of VS1, so the documented quality is consistent. The visual character of the pear, by contrast, is yours to choose. To understand how each stone reaches you, read about how we source.
Frequently asked questions
Does every pear cut diamond have a bowtie?
Most do to some degree. The bowtie is a natural result of the pear's facet arrangement, so the realistic goal is a faint bowtie that breaks up with movement rather than no bowtie at all. A pronounced, fixed shadow across the centre is the one to avoid, and it is best judged by viewing the stone face-up under even lighting.
What is the best length-to-width ratio for a pear cut?
There is no single best ratio, as it depends on the look you prefer. A ratio of roughly 1.45 to 1.55 gives the classic balanced teardrop. A lower ratio reads fuller and rounder, while a higher ratio reads longer and more elongated. Choose the outline deliberately and view the whole stone rather than relying on the number alone.
How do I protect the point of a pear cut diamond?
The point is the most exposed part of the stone, so it is usually set with a V-shaped prong that cradles and guards the tip. This is the standard approach for rings worn every day. Pendants and earrings face fewer knocks, though a secure setting is still worthwhile.
Are lab-grown pear cut diamonds the same as mined ones?
Yes. A lab-grown diamond is chemically, physically, and optically identical to a mined diamond. The same grading criteria for cut, colour, clarity, and carat apply, and the stones we offer are independently certified by IGI, GIA, or an equivalent laboratory.
