Brooches, Buckles, Earrings, and Rings, Jean Guien, 1762
The name of this French engraver working in London is known only from this series of designs, which was first published in 1710. The rapidly changing fashions made it no longer worthwhile for designers to publish their jewellery designs. Sources include complaints by goldsmiths that they depended chiefly on the size of the gemstones their clients brought them.
