Authentication Guide

Hallmarks

  • Signed with a lozenge mark (maker's mark) or fully stamped J.WIESE or WIESE.
  • Look for standard French eagle head assay marks or the boar's head for silver.

What to Look For

  • Extraordinary hand-chased sculptural details in heavy gold.
  • Use of patinated or 'bloomed' gold to give depth to the cast figures.
  • Integration of cabochon gems, intaglios, or cameos into architectural frames.

Red Flags

  • Flimsy, hollow-feeling cast pieces.
  • Modern jump rings or sloppy solder joints.
  • A complete lack of French fineness marks on what claims to be solid 18k pieces.

What Dealers Look For

1

Wiese is critically undervalued in the US market. You are getting Castellani-level craftsmanship and historical importance for a fraction of the price.

2

Jules Wiese was a master chaser before he opened his own shop. The facial expressions on his chimera and gargoyle pieces must be sharp and intentional.

3

Don't clean the dark tarnish out of the recesses of Wiese gold pieces. That patina was intentionally created to enhance the 3D relief of the sculpture.

4

Paperwork for mid-19th century Wiese doesn't exist. We rely 100% on the maker's lozenge mark and the unquestionable quality of the goldsmithing.

5

If you want a bold, heavy, wearable piece of antique jewelry that acts as a conversation starter, Wiese is the best buy in the market right now.
