How to Specify Edge Profiles for Granite Memorial Work from India
Edge profiles for granite memorial work from India are one of the most frequently under-specified elements of a purchase order — and one of the most common reasons for remakes, disputes, and delayed installations. A mason who specifies the stone variety, dimensions, and finish in careful detail will sometimes leave the edge treatment entirely to supplier interpretation, and what arrives looks nothing like what was intended. The problem is partly terminology: the names used in the UK trade for standard edge profiles do not always match what Indian processors call the same treatment. This guide covers the five profiles most commonly available from Indian stone suppliers, explains exactly what each one means, and sets out how to communicate your specification unambiguously so the edge that arrives matches the edge you ordered.
Quick Answer
The five standard edge profiles available from Indian granite memorial processors are flat polish (sawn edge taken to a polished finish), pencil round (small-radius convex curve on the top arris), bullnose (full half-round convex profile across the full thickness), bevel edge (angled flat cut at 45 degrees), and arris (sharp square edge left sawn or dressed to a fine finish). Each requires explicit specification — including profile name, dimensions, and finish — to be produced consistently. A physical sample or dimensioned drawing is the most reliable communication tool.
Why Edge Profile Specification Goes Wrong
Most edge profile problems in Indian granite memorial orders come from one of three sources: terminology mismatch between buyer and supplier, insufficient dimensional specification within a named profile, or a factory default that differs from the buyer’s expectation. All three are preventable.
Terminology mismatch is the most common issue. An Indian processor may use “pencil round” to describe a radius that a UK mason would call “fine pencil” — a 3mm curve — or they may interpret the same term as a 6mm or even 10mm radius depending on their factory’s established practice. “Bullnose” is understood consistently at its extreme (a full semicircle across the stone thickness), but interpretations diverge for partial bullnose or “half bullnose” profiles. “Bevel” is particularly prone to ambiguity: the angle, the face dimension, and whether the bevel is polished or left matte all need to be stated.
Insufficient dimensional specification is the second source. Even where both parties agree on the profile name, a pencil round without a stated radius produces whatever the factory’s tooling defaults to. A bevel without a stated face measurement produces a bevel of whatever width the factory finds convenient. For memorial work where visual consistency across pieces is commercially critical, these undetermined variables accumulate into visible differences between elements of the same set.
Factory defaults are the third source. A factory producing general export slabs will have a house standard for each profile based on the most common request from their customer base. If that house standard differs from UK trade expectations, you will receive correctly produced material — just not what you wanted. Specifying against the factory default rather than against an explicit requirement is a structural risk in any India purchase relationship.
The Five Standard Edge Profiles: What They Are and How to Specify Them
Each of the five profiles has distinct visual and tactile characteristics that make it appropriate for specific memorial applications. Understanding the intent behind each helps in specifying not just the name but the dimensions and finish that produce the right result.
Flat Polish
Flat polish is a sawn edge that has been taken through the same progressive abrasive sequence as the face — ground flat, honed, and polished to a mirror finish. The edge is square to the face with no radius, no bevel, and no relief. It is the simplest and most common edge treatment for NAMM-compliant headstone blanks, kerb sets, and tablet memorials where a clean, precise square edge is the correct finish.
To specify flat polish unambiguously, state: edge type — flat polish; finish — polished to match face (or state a minimum gloss reading, e.g. minimum 80 GU at 60°); corner treatment — sharp arris (no softening) unless you specifically want the corner broken. If you do not specify corner treatment, the factory may lightly break the arris with a coarse abrasive as a handling measure — which is generally acceptable but worth confirming if the sharp corner is important to the installation.
The faces to which flat polish applies also need stating. A headstone blank might have flat polish on the top and both side edges, with a sawn back and sawn base. State each face by name: top, left side, right side, front face, back, base. Do not rely on the factory to infer which faces are polished from a general instruction.
Pencil Round
Pencil round is a small-radius convex curve applied to the top arris of a slab or the front top edge of a headstone blank. The name refers to the approximate scale of the radius — comparable to the curved surface of a pencil — though in practice the radius varies between factories from approximately 3mm to 10mm unless specified.
Pencil round serves a practical purpose on memorial headstones: it removes the sharp corner that would otherwise be a chip risk during transit, handling, and cemetery installation, and it produces a cleaner visual transition between the polished face and the top surface when viewed from the front. It is standard on many UK memorial headstone styles and is widely understood by Indian processors producing for the UK market.
To specify: state the profile name (pencil round), the radius in millimetres (e.g. 6mm radius for a standard pencil round), the location (top front arris only, or top front and both side top arrises if appropriate), and the finish (polished to match face). If your preference is for a finer or larger radius than a standard pencil round, state the radius explicitly — “pencil round, 4mm radius, polished” is unambiguous. “Pencil round” alone is not.
Bullnose
Bullnose is a convex half-round profile running across the full thickness of the edge. Where a pencil round addresses only the top arris, a bullnose replaces the entire edge with a continuous curve from one face plane to the other — a semicircle whose diameter equals the thickness of the material. On a 30mm thick headstone blank, a full bullnose produces a rounded edge with a 15mm radius.
Full bullnose is less common on standard memorial headstones than pencil round, but is used on certain memorial styles, on kerb set capping stones, and on some tablet and ledger formats where the designer or client has specified a more finished, rounded edge profile. It requires CNC profiling tooling and adds to the processing time and cost relative to flat polish or pencil round.
Partial bullnose — sometimes called “half bullnose” or “demi-bullnose” — applies the same curved profile to one arris only rather than the full thickness, producing a convex round on the top face that transitions to a square on the side. Specify which variant is required: full bullnose (entire edge profiled) or partial bullnose (top arris only, with the stated radius). Finish is almost always polished to match face for memorial applications; state this explicitly.
Bevel Edge
Bevel edge is a flat angled cut — typically at 45 degrees — applied to one or more arrises of the slab. It removes the square corner and replaces it with an angled flat face. On a memorial headstone, a bevel on the top front arris produces a small angled chamfer that reflects light differently from the main face and can give the stone a more refined, finished appearance.
Bevel specification requires three parameters: the angle (45 degrees is standard, but other angles are possible and should be stated if they differ), the face measurement of the bevel itself (i.e. how wide the angled cut is measured across its face — common measurements are 5mm, 10mm, or 15mm for memorial work), and the finish (polished bevels are standard for memorial applications; sawn or honed bevels are sometimes used for contrast).
A common source of bevel disputes is the face measurement. An unspecified bevel will be cut to whatever the factory’s tooling produces, which may be wider or narrower than the buyer’s expectation. A 15mm polished bevel on a headstone face is a prominently visible design element; a 5mm bevel is a subtle detail. These are not interchangeable. State the face measurement in millimetres in every bevel specification.
Arris
Arris refers to the sharp meeting line between two faces of a stone — in practical specification terms, a “square arris” or “sharp arris” means the edge is left without any rounding, bevelling, or profiling. This is the natural result of cutting without any subsequent edge treatment. For sawn faces, the arris will have minor tool marks and a fine edge texture consistent with the saw blade. For faces taken to a polished finish, the arris is crisp and precise.
Specifying a sharp arris is relevant when you want the edge to remain absolutely square — for example on the back edge of a kerb set where it meets an adjacent stone, or on the base of a headstone blank that will be mortared into a base. In these situations, any rounding or chamfering would affect the joint and the installation.
An “eased arris” or “broken arris” is a minimal treatment — a very light pass with a coarse abrasive or hand file — that removes the very edge without producing a visible profile. It is a handling protection measure, not a design element. If you want a completely sharp arris, specify this and state that no easing or breaking of the arris is permitted without prior approval.
How to Communicate Edge Profiles to Indian Suppliers
Verbal descriptions and profile names alone are insufficient for quality-critical memorial production. The most reliable communication methods are dimensioned drawings and physical samples — used together where possible.
Dimensioned Drawings
A cross-section drawing showing the stone thickness, the profile shape, and all relevant dimensions (radius, bevel angle and face measurement, location of the profile on the edge) removes almost all ambiguity from edge specification. It does not need to be an engineered drawing — a clear hand sketch with dimensions noted in millimetres, transmitted as a PDF or image with the purchase order, is sufficient for a competent factory to produce the correct edge profile. The NAMM technical guidance on memorial stone specification provides a useful reference framework for the level of detail appropriate for UK memorial orders.
Include a note on finish for each edge face — “polished to match face finish” or “honed” or “sawn as cut” — as part of the drawing annotation. If the same stone has different edge profiles on different faces, note each separately. A headstone blank with a pencil round on the top front arris, flat polish on the side edges, and sawn back and base should have each of these stated individually, not summarised.
Physical Reference Samples
For profiles that are used repeatedly across a programme — a standard pencil round radius for a yard’s entire NAMM blank stock, for example — a physical reference sample is worth requesting from the factory and retaining. When the sample matches the required profile, confirm it formally and reference the sample in all subsequent purchase orders. This converts a verbal agreement into a physical standard that both parties have approved.
Physical samples are also the only reliable way to evaluate polished bevel finish under realistic lighting conditions. A polished 10mm bevel on Absolute Black granite looks quite different from the same profile on Steel Grey, and photographs do not capture the difference accurately. Request a sample piece for any new edge profile combination before committing to a full production run.
Profile Reference Numbers and Factory Standards
Many Indian processors working regularly with UK buyers have developed their own numbered or named profile reference systems based on the profiles most commonly ordered. If your supplier has such a system, ask for their profile reference sheet — it will show the profiles available with the factory’s standard dimensions, and you can either select from that list or request a modification to a standard profile with stated dimensional changes. Working within a factory’s standard profile tooling is faster and cheaper than requesting custom profiles; for most memorial applications, the standard profiles are adequate if properly selected.
The Natural Stone Specialist trade publication carries useful technical reference material on stone processing specification that is relevant to UK buyers communicating with overseas suppliers. For the specific context of Indian processing capability and UK memorial trade practice, StoneCrest International works with processing facilities that understand UK edge profile requirements and can produce to approved sample standard as part of a standard supply programme.
Common Mistakes and How to Avoid Them
Several edge profile specification mistakes recur in India memorial orders often enough to be worth naming directly.
The first is specifying a profile for the wrong face. A bevel is often intended on the top front arris of a headstone — but an instruction that says only “bevel edge” without specifying which edge will sometimes be applied to the front face, the side edges, or all arrises depending on how the factory interprets it. Always name the face: top front arris, top edge, both side edges, front base arris.
The second is omitting finish from edge profile specifications. An edge profile specified without a finish instruction defaults to the factory standard, which may be polished, honed, or sawn depending on the profile type and the factory’s practice. Always state the finish explicitly for every profiled edge.
The third is failing to specify edge profile on the back face. Memorial headstones typically have a sawn back — this is correct and expected. But if the back is to be taken to any other finish, or if the back top arris is to be treated differently from the front top arris, this needs to be stated. Many factories will apply the same profile to front and back unless instructed otherwise.
Frequently Asked Questions
What is the most common edge profile for UK memorial headstones ordered from India?
Flat polish with a pencil round on the top front arris is the most common specification for standard NAMM headstone blanks supplied from India to the UK memorial trade. The flat polish gives clean, precise side and top edges that work with standard UK inscription techniques, and the pencil round on the top front arris is a widely understood convention that provides a small degree of chip protection in transit and a clean appearance from the front. Both profiles are within the standard production capability of any established Indian granite processor supplying the UK market.
How do I specify a bevel to avoid getting the wrong size?
Always state three parameters: the angle (45 degrees unless otherwise required), the face measurement in millimetres (e.g. 10mm face), and the finish (polished to match the adjacent face is standard for memorial work). Include a dimensioned sketch showing where the bevel sits in cross-section if there is any possibility of ambiguity. A 10mm polished bevel at 45 degrees on the top front arris of a 30mm thick headstone blank is a complete specification; “bevel edge” alone is not. If you are ordering from a supplier for the first time, request a sample piece with the specified bevel before authorising bulk production.
Can Indian suppliers produce custom edge profiles not on this list?
Yes, and the range available from well-equipped Indian processing facilities is broad. CNC profiling machines can produce ogee profiles, stepped edges, multiple radii combinations, and other decorative edge treatments beyond the five standard profiles described here. The limiting factors are tooling availability and setup cost. A custom profile that requires a new profiling tool will carry a tooling charge and a longer lead time than a standard profile produced from existing tooling. For memorial programmes using custom profiles in volume, the tooling cost amortises across the order. For one-off pieces, it may be more economical to source the element from a UK stone processing facility rather than producing it in India. Discuss the profile requirement with your supplier before placing the order — most established exporters can advise on what is available in their tooling inventory without additional cost.
Does edge profile affect the lead time of an Indian granite order?
Standard profiles — flat polish, pencil round, and arris — add minimal time to production, as they are within the normal polishing line workflow. Bullnose, bevel edge, and any custom profiles require CNC profiling equipment and additional setup, which typically adds two to four working days to production time. If an order contains both standard and profiled elements, the profiled pieces often determine the production schedule. Build this into your order lead time calculation and confirm with your supplier at order placement rather than discovering the delay during production. For programme orders where the same profile is used repeatedly, the factory setup cost and time are incurred only once — repeat orders to the same profile specification typically run at normal production speed.
