Antique Art Nouveau 18K Gold Silver Diamond Brooch
Item Details
Description
  • Item: Classic Art Nouveau gold-backed silver brooch decorated with rose cut diamonds
  • Country of origin Most probably Belgium
  • Style: Art Nouveau
  • Era: ca. 1900
  • Material: Silver and 18K yellow gold (touchstone tested)
  • Technique: Gold-backed silver or the silver on gold technique. This technique finds its origin centuries ago, when jewelers believed that only a silver mounting could render the true beauty of a diamond. Backing the silver jewel with a (thin) layer of gold was a practical precaution taken to avoid the silver jewelry leaving black stains on clothing or skin. Over the years, with the recognition (and thus use) of platinum as precious metal and the development of white gold the practical necessity to use bi-colored material became obsolete. The argument to use bi-colored metals became more an esthetic then a practical one.
  • Diamonds: 18 rose cut diamonds. We do not have the weight of these diamonds which is normal in our trade when it comes to rose cuts.
  • Hallmarks: No trace.
  • Dimensions: approx. H 2,90 cm (1,14 inch) x W 4,00 cm (1,57 inch) (See also picture with a ruler in cm and inches)
  • Weight: 6,40 gram (4,12 dwt)
  • Certificate: Comes with a certificate.

    Shipping:
  • Domestic: Flat-rate of $80.00 to anywhere within the contiguous U.S.
  • International: Foreign shipping rates are determined by destination.
  • Location: This item ships from Belgium
