Imitative Jewellery
From the profuse display of what are designated “gold chains” in the windows of jewellers’ shops, there is evidently a large demand for these articles, although the purchasers are little aware of the value of the articles. The gold coin of the realm is, in technical language, 22 carats fine—that is, it consists of 22 parts by weight of fine, or pure gold, and 2 parts by weight of copper; and gold plate, &c., is 18 carats fine—that is, it contains 18 parts by weight of gold and 6 of copper in the 24. The alloy of which a large proportion of gold chains is made contains only 8 or 10 parts by weight of fine gold in the 24 parts, the remaining 16 or 14 parts being common brass. The application of brass for this purpose is of comparatively recent date, and enables the manufacturer to adulterate gold to a much greater extent than is practicable with copper alone. This depends upon the fact that brass resembles gold in colour, and copper does not. The brassy gold chains in question are far inferior in colour to chains made of gold of 18 or 22 carats fine, and they would hardly be tolerated by many persons when seen side by side with those of the latter description. They are now manufactured on a very large scale by the aid of machinery, and so great has been the decrease in their cost of production, that the value of the labour upon certain kinds of chains has been reduced from 30s. to 3s. 6d., or even less. It is usual to deposit upon the finished chain an exceedingly thin coating of pure gold by the electrotype process. This, of course, is speedily worn off by friction, and consequently the original fine colour of the chain at the time of purchase disappears. The propriety of this practice is questionable. If the public like cheap brassy gold chains, and are satisfied with their appearance, it is their own affair, and no one has a right to say a word; but, in buying such articles, beware of the small value of the materials in comparison with gold.19
