This unusual brooch draws its design from a piece originally created by L. Coulon et Cie for the Exposition Universelle in Paris, which took place in 1900. The distinctive blackened openwork of the petals was a technique explored in various metals by several jewellery houses at the beginning of the 20th century, most notably Boucheron, where it was used primarily in jewels of bow design, playing upon its resemblance to black lace.
Cf.: Gilles Neret, Boucheron: Four Generations of a World-Renowned Jeweller, Switzerland, 1988, pg. 67, for a platinum and diamond bow brooch in a similar open work technique in the Boucheron collection, dated 1908.
