Setting height, measured
Setting height is the distance from the top of your finger to the top of the diamond. Nobody at a counter will say it that way. They will say a ring sits high or sits low, and both of those are opinions until somebody puts a gauge on it. So here are four settings around the same stone, drawn to one millimetre scale.
Four profiles, one stone, one scaleMeasured at our bench on a 1.25 ct round brilliant, about 7 mm across and 4.3 mm deep from table to culet. That stone accounts for most of the lowest column here, which is the point: no setting can go below the depth of the diamond it holds. Individual rings run a millimetre either way, and a halo or a deeper cut adds to every figure. We know of no published Australian data on setting heights; these are our own measurements.
Two things fall out of the drawing. The first is that the stone sets the floor. A 4.3 mm deep diamond cannot sit less than 4.3 mm off the finger, so the lowest setting on the market is mostly stone and hardly any metal. The second is that the gap between the ends of the range is bigger than it sounds. Six millimetres does not read as a large number until you know that a plain wedding band is about 1.5 mm thick. The gap between the lowest column and the tallest is four of those, stacked.0 mm

The number to ask forAsk any jeweller for the profile height in millimetres before you commit to a design. It is a measurement, not a matter of taste, and a maker who cannot give it to you has not thought about how the ring will be worn.
What a low setting is
A low setting is one where the stone is brought down as close to the finger as its own depth allows. In practice that means a total profile of roughly 5 to 6 mm on a one to one-and-a-half carat stone, a little less on something smaller, and it is achieved in one of three ways: the head is dropped into a seat cut in the shank rather than perched on top of it, the pavilion is allowed to pass through the band into the space above your finger, or the stone is bezelled, with a rim of metal wrapping the girdle and no basket underneath at all.What you notice wearing one is the absence of things. It does not catch. It does not rotate much, because there is no weight up high to swing. It slides under a glove and under a shirt cuff, and when you close your fist it does not press into the finger beside it. People who wear low-set rings tend to stop thinking about them, which for a ring you never take off is the whole point.The trade-offs are real and worth naming. The underside of the stone is close to skin, so less light gets in from the side and the pavilion picks up the colour of the finger behind it. It is harder to clean, because a brush cannot get to the part that most needs brushing. And the stone reads slightly smaller, partly because a bezel rim covers the outer edge of the girdle and partly because nothing sitting flat casts a shadow.
In one sentenceA low setting is a stone brought down to within a millimetre or two of the finger, usually 5 to 6 mm of total profile, chosen for comfort and for not catching on anything.
What counts as high set
There is no standard, and anyone quoting you an official threshold has invented it. What the trade means by high set is a ring where the metal deliberately lifts the stone well clear of the band, and on the stone sizes most people buy that starts at about 8 mm of profile and runs past 12 mm. Three designs get you there: a tall basket on a long peg, a cathedral where arches sweep up from the shoulders to meet the head, and a halo on a raised head, which adds the height of the halo to everything else.
Same stone, three profiles
The cathedral is the one people get wrong. It is not automatically taller than a plain raised head. Its arches are a shape rather than a height, and you can have a low cathedral. What the arches change is how much metal you see from the side and how the ring meets a wedding band, which we come back to below.The other thing worth knowing is that carat weight raises the floor on its own. A three carat round is about 9.3 mm across and 5.7 mm deep, so a setting that would count as low on that stone is taller than a raised setting on a one carat. When someone tells you a large ring sits high, sometimes the setting is doing it and sometimes it is just physics.Raised solitaireThe head sits on top of a plain band, lifting the girdle clear of the finger. Light enters from the sides; the ring stands proud of the hand.
CathedralArches sweep up from the shoulders to meet the head. Similar height, more metal on show, and the arches shade the lower half of the stone.
Low-setThe stone drops down towards the band. Snags less on jumpers and gloves, sits flatter under a wedding band, catches less light from the side.
In one sentenceHigh set means the metal lifts the stone clear of the band on purpose, generally 8 mm or more of profile, whether by a tall basket, cathedral arches or a raised halo.
Why rings got set so high
It was an argument about light, and it was won in 1886. Before then, fine stones were commonly set in closed-back mounts, sometimes over metal foil, with the back of the gem sealed away from daylight. Tiffany & Co. dates its six-claw solitaire to that year, and the pitch was exactly this: lift the diamond off the band on a slender head so light can reach it from every direction. The design was copied by every jeweller on earth and is still the default shape of an engagement ring, which is why so many rings sit high without anyone having chosen it.How much of that light argument still holds is worth being honest about. Most of what you see in a well-cut diamond is light that went in through the table and came back out the same way, and that happens whether the back is open or not. Where an open, lifted setting genuinely helps is at the edges of the stone and underneath it. A pavilion resting against skin reflects skin. Lift it a few millimetres and the same facets have daylight behind them instead. The effect is small on a deep, well-cut round and much more noticeable on a shallow stone or a step cut.
A raised head is also easier to make. The setter can get a graver and a loupe underneath it, and so can whoever retips the claws in fifteen years.The rest of the answer is less romantic. A raised head is faster to set and cheaper to repair. An open basket is the only version of a ring you can properly clean at home. A lifted stone throws a shadow and picks up a light source from more angles, so it photographs bigger, and rings have been sold from photographs for twenty years now. And a head lifted clear of the band is the one shape that lets a plain wedding band sit flat against it, which matters more to most people than anything about light.
Height, weighed both ways
What the height buys
A pavilion that is not pressed against skin. Light reaches the sides of the stone and the underside reflects daylight rather than the colour of a finger.
An open back you can clean. A soft brush and warm water reach the underside, which is exactly where the film that dulls a diamond collects.
Room for the setter. Seats get cut and claw tips get closed with the shank out of the way, and the same is true when the ring comes back for a retip in ten years.
Presence. A lifted stone catches a light source from more angles and reads larger in a photograph than the same weight sitting flat on the hand.
What the height costs
Claw tips at the highest point of the ring, which is the part that finds jumper sleeves, hair, upholstery and the lining of a bag.
Leverage. A knock a low ring would shrug off arrives at the end of a lever instead, and that is how claws bend and girdles chip.
A top-heavy ring. If your knuckle is much wider than the base of your finger, a tall head will spend the day drifting round to the side.
Pressure under anything tight. A glove, a barbell, a steering wheel and a sleeping hand all press on the tallest point first.
What a tall ring catches on
Nothing about a high setting is dangerous. It is just that the highest point of a ring is a set of claw tips, and claw tips are small, hard and slightly hooked. Over a few years they find wool, hair, car upholstery, the inside of a handbag, the pocket of a pair of jeans and the cuff of a jumper. Most of those encounters cost you nothing. A few of them bend a claw, and a bent claw is how a stone eventually goes missing.The bigger risk is leverage rather than snagging. A ring on a hand gets knocked against door frames, car doors, kitchen benches and gym equipment, and the taller the head, the longer the lever arm the knock is working through. That is why claws on high settings need checking more often and why chipped girdles turn up on tall rings more than short ones. We would put a high-set ring in front of a jeweller once a year and a low one every second year.There is also the spinning problem, which is nothing to do with damage and everything to do with irritation. A ring has to pass a knuckle, so it is always a little loose at the base of the finger. A tall head is weight sitting well above the axis of the finger, and weight above an axis rotates. If your knuckle is much wider than your base, a high setting will spend the day sliding round so the stone faces your palm.
The Australian version of thisWarm weather is the part people underestimate. Fingers swell in summer, so the ring goes on tighter and comes off harder, and hands are out of pockets and into salt water, sunscreen and gardens for months at a time. None of that argues for one profile over another on its own, but it does mean a ring here is worn on a bare, active, slightly swollen hand more of the year than a ring in London is. We are not aware of any Australian study that measures this. It is simply what we see.
Where the wedding band goes
This is the part that surprises people, and it is the strongest practical argument for height. A plain wedding band wants to sit flat against the shank of your engagement ring. Whether it can depends entirely on what is hanging over the shank in the bottom millimetre and a half.
One plain band, three engagement ringsSchematic cross-sections at the same scale, drawn from the geometry rather than measured from photographs. The finger runs left to right and both rings are cut through, so the wedding band appears beside the shank rather than behind it.
A raised head is the friendliest thing you can pair a straight band with, because everything wide about the ring is up in the air where the band is not. A low bezel is the hardest, because the rim is wider than the shank and reaches down to where the band wants to be, so you either notch the band, curve it, or accept a visible gap. A cathedral sits in between: nothing blocks the band, but the arch rises past it and leaves a step, which is why cathedral rings so often come with a contoured band designed alongside them.None of this is a reason to rule anything out. Contoured and notched bands are ordinary work, and a good maker will cut one to your ring rather than sell you a stock curve that nearly fits. But it is worth knowing before you choose, because the wedding band is the second ring and it is easier to design the pair together than to solve it two years later. If you are choosing a design from scratch, our guide to how settings work covers the other choices that sit alongside height.Head lifted clearNothing overhangs the shank below the height of a plain band, so a straight wedding band slides all the way in and touches along its whole edge. This is the easiest pairing there is.
Low bezelThe rim is wider than the shank and reaches down to within a millimetre of the finger. A straight band stops against it and stands off by two or three millimetres, so the band gets notched or curved to fit.
Cathedral shoulderNothing blocks the band here. The arch simply rises past it, so a straight band leaves a step where the two meet. The gold line is the contoured band that follows the arch instead.
Which one is for your hand
The question is not which setting is better. It is how much of your week the ring spends on a hand that is doing something. Here is how we would answer it for the hands people describe to us most often.
Six hands, and the profile we would steer each towardsOur own view from fitting, sizing and repairing rings, not a study. We know of no Australian data linking setting height to damage or loss, and we would be sceptical of anyone who quoted you a figure.
Go low
Nurses, carers, and anyone in and out of glovesNitrile finds a claw tip immediately, and a torn glove at work is a problem rather than an annoyance. A bezel or a low four-claw head ends the argument.Go low
Weights, climbing, and the monkey barsLoad on a band presses it out of round, and a raised head takes the blow first. The honest answer for a barbell is to take the ring off. A low profile is the fallback for the days you forget.High is fine
Desk work, with the ring off for the gardenNothing in that week punishes height. If the ring lives on a hand that is mostly typing, buy the profile you like looking at.High is fine
Long fingers, or a stone over two caratsHeight is what stops a large stone reading as a slab lying on the hand, and a deep pavilion has to go somewhere. Dropping a big stone right down usually looks heavier, not daintier.Go low
A knuckle much wider than the base of the fingerThe ring is going to rotate, and a tall head turns rotation into a stone that spends the day facing sideways. Keeping the weight low and close is the only fix that does not involve resizing.Either works
A stone under a carat, on a small handThe pavilion is shallow enough that a low setting costs almost no light, and a raised head keeps a modest stone from disappearing into the finger. Choose this one on looks.What we would actually recommendFor an everyday Australian wearer, a moderately low profile: a head dropped onto the band rather than perched on a peg, a compact basket, short claws, and a total profile around 6 to 7 mm on a one to one-and-a-half carat stone. It keeps almost all of the light and nearly all of the cleaning access of a raised setting, and it loses the snagging and most of the spinning. If your hands work hard, go further and bezel it. If the ring is coming off for anything physical anyway, ignore all of this and buy the cathedral.
Whatever you choose, try the height before the design is final. Wear a sample for ten minutes, put a hand in a pocket, pull a sleeve over it, and make a fist. That is more informative than any drawing on this page, including ours, and a maker who will not let you do it is the wrong maker.Not sure which way to go?Tell us what your hands do in an ordinary week and we will give you a profile height in millimetres, a setting that hits it, and an honest answer about what a wedding band will need to look like next to it.
