Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'индустриальный бриллиант'. Use 'технический алмаз' or 'промышленный алмаз'.
- Do not confuse with 'industrial' meaning 'related to factories' only; here it specifies 'non-decorative, functional use'.
Common Mistakes
- Using 'industrial diamond' to refer to a large gemstone. (Incorrect)
- Pronouncing 'diamond' as three syllables /ˈdaɪ.ə.mənd/ in American English (it's typically two: /ˈdaɪ.mənd/).

FAQ
Frequently Asked Questions
Yes, they are real diamonds (carbon arranged in a diamond cubic crystal structure) but are either of low gem quality or synthetically produced for functional purposes.
Almost never. They lack the clarity, colour, and size required for jewellery. Their value lies in their physical properties, not their appearance.
'Bort' (or boart) is a specific type of industrial diamond—a poorly crystallized, granular, or dark diamond aggregate. 'Industrial diamond' is the broader category that includes bort, synthetic diamonds, and other low-quality diamonds used in tools.
The majority are now produced synthetically using High-Pressure High-Temperature (HPHT) or Chemical Vapor Deposition (CVD) processes, as this allows for controlled production of specific sizes and properties.
