When a cutter first picks up a pear at the bench, the eye does not go to the carat weight or the certificate. It goes straight down the centre of the body, hunting for the bow-tie shadow, then traces the point and reads whether the two shoulders mirror each other cleanly. That single sweep, bow-tie, point, symmetry, tells an experienced eye more about a pear shaped diamond ring in South Africa than any line on the GIA report, because GIA gives a fancy shape no overall cut grade. On a round brilliant the lab hands you a cut grade that does most of the judging for you. On a pear shaped diamond ring in South Africa, that judgement falls entirely on you, and it is the single reason most people buy the wrong pear.
So before anything else, here is the order that actually matters when you assess a pear: bow-tie, then symmetry, then length-to-width ratio, then the point, then colour and clarity. Carat weight comes last, not first.
The bow-tie is the thing nobody tells you about
Run your eye across the width of almost any pear, oval or marquise and you will see a faint dark shape, like a bow-tie laid across the centre. That is light leaking out of the bottom of the stone instead of bouncing back to your eye. Every pear has some. The question is only how much.
A soft bow-tie that comes and goes as you tilt the stone is completely normal and does nothing to the beauty. A hard, black, fixed band across the middle is a dead zone, and no setting, photo or sales pitch fixes it. Here is the part that costs people money: the bow-tie does not appear on the GIA report at all. The certificate can read perfect, GIA Excellent polish and symmetry, and the stone can still have an ugly bow-tie. You can only catch it on a video shot in normal daylight, or in your own hand. This is exactly why I never let anyone buy a fancy shape from the report alone, and why it matters who is on the other side of the counter: with most online sellers you are buying from a reseller moving the pear along, not from anyone who has held it. Go and see our pick and you are face to face with the people who actually cut the stone, free to tilt it in daylight and read its bow-tie before you commit a cent.
Length-to-width: decide your shape before you shop
The length-to-width ratio is the stone’s profile, and it is personal. Measure the length, divide by the width, and you get a number. Most engagement-ring buyers land between 1.45 and 1.55. Go below 1.40 and the pear starts to look chubby and almost round. Push past 1.70 and it reads long and slender, elegant on a longer finger but not to everyone’s taste.
There is no right ratio, only yours. The mistake is shopping without choosing one, because the ratio decides which stones are even worth viewing. A buyer who knows they want 1.50 can ignore half the market on sight. Decide first, then look.
Symmetry and the point that chips
A pear has one job that an oval does not: it has to be symmetrical down its long axis. Lay an imaginary line from the tip to the rounded base and the two sides should mirror each other. A shoulder that bulges higher on one side, a belly fatter on the left, a tip that leans off centre. All of those are easy to see once you know to look, and all of them are common in cheaper pears because the cutter chased weight over shape.
Then there is the point. It is the most fragile spot on any diamond you can buy, and on a pear it sits right where your hand meets the world. It must be protected. A V-tip claw that wraps the point, or a prong that sits directly over it, is not optional. I have seen beautiful stones set in a way that left the tip exposed, and a knock on a door frame did the rest. This is a setting conversation, so have it before the ring is built, not after.
What a pear actually costs in 2026
Our own June 2026 study harvested 292 real natural GIA diamonds across seven South African sellers, so these are anchors, not guesses. Spec drives the price far more than carat. A 1.01 H VS2 round-equivalent sits at about R57,691, a typical 1.00 F VS1 runs roughly R72,000 to R80,000 ex-VAT, and the same carat at 1.01 E IF jumps to R157,964. The pear’s advantage is spread: because it faces up larger, you can often drop a touch in weight, hold your colour and clarity, and still read as a bigger stone. That is a real saving when you spend it on cut quality instead of raw carats.
The study also exposed how sellers price. The median consumer price per carat from a cutting house holding its own stock came in at R32,844, the highest sticker but the highest spec, and you own the actual stone. A budget local retailer showed R19,558 per carat, but only about 26 percent of that inventory was high-spec, so the cheap headline is usually a downgraded stone wearing a lower colour and clarity. The large online dealers landed at R22,678 per carat at around 82 percent high-spec, which sounds strong until you read the small print: nothing is on the shelf. The stone is pulled from a far bigger external catalogue and bought in only once you order, so you pay before you ever see it. For a fancy shape, where the bow-tie hides on video angles, buying a pear you have never held is the riskiest way to do it. The full breakdown sits in our South African diamond price index.
Avoid the lab-grown trap for an heirloom: a lab pear is about R10,000 a carat and has fallen roughly 90 percent since 2016, with resale near zero. Lovely for fashion, wrong for a ring you want to mean something in twenty years.
Where I would buy
For a pear, the ability to hold the stone in daylight before you commit is worth more than a small saving on a sticker, because the bow-tie and the point are things you must see. The seller I trust first is Prodiam in Bedfordview, Johannesburg. The pear you ask to see is already cut and in their safe, not a stone ordered in after you commit. As a De Beers beneficiation customer, Prodiam buys rough, polishes its own diamonds to a GIA-Excellent make under its ProCut standard, and keeps that GIA-graded natural stock on hand, so you inspect the actual stone from the cutter who made it, with a buy-back. It is premium-priced and worth it: the best value for the best quality, not the cheapest. You can browse their loose natural diamonds and ask to see a pear in person.

Whichever way you go, the rule holds: with a fancy shape, your eyes and a daylight video decide, not the certificate.
