# Natural industrial diamonds, unworked or simply sawn, cleaved or bruted; pumice, emery and other natural abrasives

## 1. Scope and Applicability

Supply of natural industrial diamonds, unworked or only simply sawn, cleaved or bruted, and pumice stone, emery, natural corundum, natural garnet and other confirmed natural abrasives at one declared recovery/preparation/loading gate or explicitly included plant-receipt gate. Natural non-diamond abrasives may be crude, washed, crushed, ground, powdered, sieved or physically concentrated; actual heat-treated natural abrasives are admitted by HS2513 and require declared treatment and retained natural identity. Do not transfer the diamond rough-state restriction to natural abrasive powder, or transfer abrasive powder admission to diamond dust/powder. Every dataset selects one identified whole product and accepted size/performance grade. Actual families have distinct primary quarry/host-rock or placer routes; pumice can use simple surface mining and screening/crushing, emery is a naturally mixed mineral rock rather than pure corundum, natural corundum needs its own ore and supplier identity, and garnet may require actual washing, jigs, gravity/density, magnetic or flotation concentration. Diamond DMS/Xray/grease recovery applies only to an actual appropriate natural-diamond circuit, not to all abrasives. Standalone preparation of externally supplied qualified natural materials is allowed with upstream extraction burdens carried by the supplier. Unworked diamonds do not force sawing/bruting; prepared abrasives do not force washing, flotation, drying or thermal treatment. Additional other natural abrasive varieties require confirmed category/state and a separate atomic mineral/resource/product row; natural novaculite abrasive stone is an example only when its actual category is confirmed, not a license to relabel industrial sand or diatomaceous earth. Synthetic/reconstructed diamonds and manufactured/fused/sintered abrasive minerals are outside this natural category; CPC34560 separately names unworked synthetic/reconstructed precious or semiprecious stones, while CPC38230/HS7105 separately name diamond/gem dust/powder and further worked industrial diamonds. Bonded grinding wheels, coated paper/cloth, abrasive formulations, cleaning preparations, polished gems, jewellery and downstream abrasive use lie beyond this mineral gate. `wco-natural-abrasives-2022`, `wco-diamond-boundary-2022`, `usgs-industrial-garnet-2006`, `epa-natural-abrasives-1976`, `gia-diavik-2016`, `nist-carat`

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| reference_basis | final_product | Mass | kg | D is the positive accepted net gate-output total in kg. Exclude packaging and cancelled internal transfers. cp_output records D; every card uses per 1 kg reference flow. |
| conversion | utility and material rows | Declared row property | kg; m3; MJ | Retain raw readings. Electricity: 1 kWh = 3.6 MJ. Mass/volume conversion requires measured density, temperature and applicable pressure; retain water content and active chemical fraction. |
| category_balance | production | Mass | kg | Reconcile independently measured feed, accepted whole-product D, other accepted grades/co-minerals, waste rock, tailings/fines, dust, saw residue, water/evaporation and opening/closing stock on matched wet and dry-solids bases. kg_dry=kg_as_received*(1-free_moisture_fraction); mineral assay and structural water are separately measured, not subtracted as free water or substituted for whole-product D. Emery retains its natural phase mixture. Thermal treatment changes need actual mass/water/emission evidence, not a universal decomposition factor. Diamond metric carats convert kg=ct*0.0002; grams kg=g*0.001 for the same accepted parcels. Piece count cannot convert without measured paired weights. Measure accepted grade output independently, not as feed minus assumed waste or recovery. |

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| allocation_hierarchy | joint production | Prefer process subdivision or defensible system expansion; otherwise use demonstrated physical causality. Use economic allocation only with consistent period, price, currency and sensitivity when physical causality is unavailable. Retain the unallocated inventory. | `ef-allocation-2021` |
| allocation_product | reference and co-products | Separate industrial/nonindustrial diamond parcels, abrasive size/performance grades and actually accepted co-minerals before reference normalization. Subdivide separately metered stages first; allocate genuinely shared mine/recovery burdens by a documented causal physical relationship when demonstrated, otherwise justified actual economic shares using independently measured quantities and matched observed prices/currency/period, with sensitivity. Retain unallocated totals and output weights. No invented gem price, universal recovery or hardness-based allocation. Unsold reject is waste by actual fate; neither sale nor a co-output name alone creates an avoided-product credit. |  |
| allocation_waste | waste and recycling | Classify each output by physical state and actual fate. A sale does not automatically make a residue a co-product; internal recycling receives no avoided-product credit. Apply treatment burdens once. |  |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| normalization | all cards | Exchange = attributable period quantity / D. Reconcile inventories and cancel internal transfers before aggregation. | cp_output; row-specific cp records | per 1 kg reference flow |  |
| physical_balance | production | Reconcile independently measured feed, accepted whole-product D, other accepted grades/co-minerals, waste rock, tailings/fines, dust, saw residue, water/evaporation and opening/closing stock on matched wet and dry-solids bases. kg_dry=kg_as_received*(1-free_moisture_fraction); mineral assay and structural water are separately measured, not subtracted as free water or substituted for whole-product D. Emery retains its natural phase mixture. Thermal treatment changes need actual mass/water/emission evidence, not a universal decomposition factor. Diamond metric carats convert kg=ct*0.0002; grams kg=g*0.001 for the same accepted parcels. Piece count cannot convert without measured paired weights. Measure accepted grade output independently, not as feed minus assumed waste or recovery. | Matched mass, volume, composition and stock measurements | Balance residual and uncertainty |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| representativeness | dataset | Use matching production and exchange periods, actual technology, geography and supplier state. Record startup, shutdown, seasonal variation and substitutions. | collection records |
| identity_and_ranges | all cards | Unresolved identities and missing independent range evidence remain explicit. Do not replace measurement by a guessed industry range or by missing-as-zero. | manifest review metadata |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| validate_reference | final_product | Verify 1 kg, positive D, product state, property/unit and every required qualifier. Each dataset fixes one product and route. |  |
| validate_balance | site | Reconcile independently measured feed, accepted whole-product D, other accepted grades/co-minerals, waste rock, tailings/fines, dust, saw residue, water/evaporation and opening/closing stock on matched wet and dry-solids bases. kg_dry=kg_as_received*(1-free_moisture_fraction); mineral assay and structural water are separately measured, not subtracted as free water or substituted for whole-product D. Emery retains its natural phase mixture. Thermal treatment changes need actual mass/water/emission evidence, not a universal decomposition factor. Diamond metric carats convert kg=ct*0.0002; grams kg=g*0.001 for the same accepted parcels. Piece count cannot convert without measured paired weights. Measure accepted grade output independently, not as feed minus assumed waste or recovery. |  |
| validate_coverage | handoff | Verify each applicable exchange, its provider or environmental compartment and final waste fate; identify skipped checks, unresolved identities, missing measurements and upstream gaps. Errors or unassessed mandatory coverage cannot be labelled complete. |  |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | foreground_dataset |
| downstream_use | secondary_dataset; background_dataset |
| allowed_use | Supply one independently accepted declared-grade natural industrial diamond or natural abrasive mineral/rock lot at the specified gate |
| excluded_use | Nonindustrial gem reference products; synthetic/reconstructed diamonds; artificial/fused/sintered corundum or other manufactured abrasives; diamond/gem dust and powder or further worked diamonds as reference; formulated bonded/coated abrasive articles and cleaning preparations; jewellery; nonmatching sand/diatomaceous earth/aggregate categories; downstream use |
| required_metadata | Natural origin; deposit/mineral or rock identity including emery phase mixture and garnet species; primary/placer/supplied route; actual processing and heat-treatment state; diamond industrial grade and permitted simple-cut state; accepted whole-product grade and size distribution; measured abrasive performance/contaminant specification where claimed; free moisture and structural-water basis; independent positive accepted D; gate/geography/period; provider/grid voltage; cutoff and equipment lifetime; outputs/allocation/waste fate. No assumed hardness, mineral purity, recovery, thermal recipe, price or yield. |
| required_quality_disclosure | Identity and measurement gaps; boundary coverage; uncertainty; allocation; temporal and geographical representativeness |
| update_trigger | Changed product, route, yield, supply, waste fate, site or representative period |
