Pear diamond size chart
A teardrop: round at one end, pointed at the other. A pear combines a round's brilliance with a marquise's point. It looks large for its weight and lengthens the finger, and it's traditionally worn with the point toward the fingertip.

What to know about pear diamonds
Protect the point
The tip is the most delicate part of the stone. A V-shaped prong folded over the point protects it, which is why a pear is usually set with five prongs: the V at the tip and four around the curve.
Watch for the bow-tie
Like ovals and marquises, pears can show a dark bow-tie across the middle. A faint one is normal; check photos of the actual stone.
Ratio and symmetry
Popular ratios run from about 1.45 to 1.75. Look for shoulders that match on both sides, so the point sits straight down the middle.
Length-to-width ratio
Two pears of the same weight can look quite different. These three all weigh 1 ct; only the ratio changes — from 8.1 mm long at 1.45 : 1 to 8.9 mm at 1.70 : 1. It's a matter of taste, not quality.
Pear vs round
The dashed line is a 1 ct round. A 1 ct pear covers about 2% more area from above.

0.25 carat pear
How big is a 0.25 carat pear diamond?
About 5.3 × 3.4 mm, and it looks about as big as a 0.26 ct round. Laid on a US dime (17.91 mm), it would cover about a third of the coin's width lengthwise and a fifth of it across.
Small and delicate
A quarter carat reads as a bright point of sparkle rather than a statement. It's a lovely size for minimalist and stacking rings and for anyone who wants something that sits close and never catches, and it leaves room in the budget for a better cut or color. As a pear, it covers about the same area from above as a round of the same weight, so it reads true to its carat.
Want it to look bigger?
A halo of small diamonds around it takes the face-up width from 3.43 mm to about 4.7 mm — 38% wider — for much less than a bigger center stone would cost.
The same size in other shapes
To cover the same area from above you'd need about 0.26 ct in a round, 0.23 ct in an oval and 0.30 ct in a cushion.

0.5 carat pear
How big is a 0.5 carat pear diamond?
About 6.7 × 4.3 mm, and it looks about as big as a 0.51 ct round. Laid on a US dime (17.91 mm), it would cover about two-fifths of the coin's width lengthwise and a quarter of it across.
Petite and practical
Half a carat is a classic petite size: noticeable without being showy, comfortable for everyday wear, and easy to set low so it doesn't snag on gloves or knitwear. As a pear, it covers about the same area from above as a round of the same weight, so it reads true to its carat.
Consider 0.45 ct
Prices tend to step up at round weights like 0.5 ct. A 0.45 ct pear measures about 6.47 × 4.17 mm — only 0.15 mm narrower, with 7% less area on top. That's very hard to see on a hand.
Want it to look bigger?
A halo of small diamonds around it takes the face-up width from 4.32 mm to about 6.0 mm — 38% wider — for much less than a bigger center stone would cost.

0.75 carat pear
How big is a 0.75 carat pear diamond?
About 7.7 × 4.9 mm, and it looks about as big as a 0.77 ct round. Laid on a US dime (17.91 mm), it would cover about two-fifths of the coin's width lengthwise and a quarter of it across.
Just under the milestone
Three-quarters of a carat gives a good share of the look of a one-carat stone, and on a slim finger the difference can be hard to see. It's a sensible size if the budget is better spent on cut quality or the setting. As a pear, it covers about the same area from above as a round of the same weight, so it reads true to its carat.

1 carat pear
How big is a 1 carat pear diamond?
About 8.4 × 5.4 mm, and it looks about as big as a 1.02 ct round. Laid on a US dime (17.91 mm), it would cover about half of the coin's width lengthwise and a third of it across.
The milestone size
One carat is the size many people picture when they think of an engagement ring. It's clearly a center stone without being heavy, and it suits almost every setting style. As a pear, it covers about the same area from above as a round of the same weight, so it reads true to its carat.
Consider 0.9 ct
Prices tend to step up at round weights like 1 ct. A 0.9 ct pear measures about 8.15 × 5.26 mm — only 0.19 mm narrower, with 7% less area on top. That's very hard to see on a hand.
Turned east–west
Set across the finger instead of along it, its 8.44 mm length spans 48% of a size 6 finger instead of 31%. A modern look that reads wider.

1.25 carat pear
How big is a 1.25 carat pear diamond?
About 9.1 × 5.9 mm, and it looks about as big as a 1.28 ct round. Laid on a US dime (17.91 mm), it would cover about half of the coin's width lengthwise and a third of it across.
A step past one carat
A quarter carat over the milestone. It reads as noticeably substantial on most hands while still sitting comfortably in standard settings, and it avoids the round-number weights where prices tend to jump. As a pear, it covers about the same area from above as a round of the same weight, so it reads true to its carat.
Turned east–west
Set across the finger instead of along it, its 9.09 mm length spans 51% of a size 6 finger instead of 33%. A modern look that reads wider.

1.5 carat pear
How big is a 1.5 carat pear diamond?
About 9.7 × 6.2 mm, and it looks about as big as a 1.54 ct round. Laid on a US dime (17.91 mm), it would cover about half of the coin's width lengthwise and a third of it across.
A clear statement
At a carat and a half, the stone is the first thing people notice about the ring. It's still easy to wear every day, but cut quality starts to show more, because there's more stone to see. As a pear, it covers about the same area from above as a round of the same weight, so it reads true to its carat.
Consider 1.4 ct
Prices tend to step up at round weights like 1.5 ct. A 1.4 ct pear measures about 9.44 × 6.09 mm — only 0.14 mm narrower, with 4% less area on top. That's very hard to see on a hand.
Turned east–west
Set across the finger instead of along it, its 9.66 mm length spans 55% of a size 6 finger instead of 35%. A modern look that reads wider.
Five prongs or six
A pear is usually held with five prongs: a V over the point and four around the curve. A sixth at the rounded end adds security for a stone this size.

2 carat pear
How big is a 2 carat pear diamond?
About 10.6 × 6.9 mm, and it looks about as big as a 2.05 ct round. Laid on a US dime (17.91 mm), it would cover about three-fifths of the coin's width lengthwise and two-fifths of it across.
A large stone
Two carats is big on most hands and is seen from across a room. At this size clarity and color are easier to judge by eye, and a secure head matters more, so ask how it's set. As a pear, it covers about the same area from above as a round of the same weight, so it reads true to its carat.
Consider 1.9 ct
Prices tend to step up at round weights like 2 ct. A 1.9 ct pear measures about 10.45 × 6.74 mm — only 0.12 mm narrower, with 3% less area on top. That's very hard to see on a hand.

2.5 carat pear
How big is a 2.5 carat pear diamond?
About 11.5 × 7.4 mm, and it looks about as big as a 2.56 ct round. Laid on a US dime (17.91 mm), it would cover about two-thirds of the coin's width lengthwise and two-fifths of it across.
Very large
Two and a half carats is a very large stone for everyday wear. Setting height starts to matter: a lower head snags less, and a sturdy one protects a stone this valuable. Many owners have it appraised for insurance. As a pear, it covers about the same area from above as a round of the same weight, so it reads true to its carat.

Dramatic
Three carats is a show-stopping size. It dominates all but the broadest fingers, so seeing it on your own hand before buying matters more here than at any other size. Look for a head made for a stone this size, and insure it. As a pear, it covers about the same area from above as a round of the same weight, so it reads true to its carat.
