Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'ложный бриллиант'. Use 'поддельный бриллиант' (fake diamond) or 'имитация бриллианта' (diamond imitation) for the literal meaning. For the figurative sense, use 'обманчивая внешность' or 'пустышка'.
Common Mistakes
- Using 'wrong diamond' or 'untrue diamond'. Confusing with 'blood diamond' (which is a real, but unethically sourced diamond).

FAQ
Frequently Asked Questions
Cubic zirconia is one common type of false diamond (a simulant), but 'false diamond' is the general category.
Yes, figuratively. It describes someone who appears impressive, trustworthy, or valuable but is fundamentally not.
A key difference. A synthetic diamond is chemically a real diamond, just lab-grown. A false diamond is a different material (like glass or CZ) made to look like one.
Not very common. It's more likely found in writing or formal speech. In casual talk, people might say 'fake diamond' or use a metaphor like 'all flash, no substance'.
