Antiques - definition and age
Stylish and stylized objects
A common layman's dilemma and abuse field for unreliable sellers.
A stylish object is simply ... an original, created in a particular the era, style, artistic circle, etc. What's important is that maybe, but not necessarily he is an antique (e.g. 20 or 30 years old). Age is completely irrelevant here. Both the Romanesque crucifix (antique) will be a stylistic object, as well as this cabinet from 70's furniture store (not antique).
A stylized object is a later one (usually completely contemporary) imitation of the original, i.e. a stylish object. Quality imitation is very different - from worthless trash, produced machine-tooled in the Far East from plastic or waste, up to high artistic class handmade in wood.
Replicas, copies, forgeries ...
For most people, these three terms are ...the same, meaning fraud. Unfortunately, nothing more wrong.
A replica - is a re-made (usually by the author of the original or his studio) work, which is also sometimes a slightly modified and improved "version" of the original.A copy is produced for teaching purposes, as a souvenir, exhibition or decorative, precise reproduction of the original, clearly and permanently marked as a copy (often with manufacturer's data).
Falsification - is, on the other hand, a deliberate fraud, i.e. an imitation of the original, not marked as true as possible, produced solely for the purpose of mystification for financial gain. Selling counterfeits and copies as originals is punishable.
