Archaeological Revival

1860s-1895

Giuliano's bread and butter. Ancient Greek, Etruscan, and Roman aesthetics remade for the most discerning Victorian elite. The enamel work here is top-tier, easily rivaling Castellani.

Authentication Guide

Hallmarks

  • ◆Most pieces carry the 'C.G.' monogram inside an oval.
  • ◆Sometimes you'll see 'CARLO GIULIANO' stamped in full. Don't worry if it's partly rubbed; we look at the work first.

What to Look For

  • ✓The enamel borders. Giuliano's black and white enamel detailing is incredibly precise.
  • ✓Immaculate gold work with exact, tight wirework and granulation.

Red Flags

  • ✗Sloppy enamel that bleeds over the gold borders.
  • ✗Lightweight, flimsy construction. Real Giuliano feels dense and impeccably engineered.

What Dealers Look For

1

Archaeological Revival is getting extremely hot. Prices are marching up steadily—buy the best example you can find right now.

2

Original fitted boxes from his Piccadilly shop add real premium value; collectors love the complete package.

3

Look closely at the gems. Giuliano used great stones, but the value is in the gold and enamel work. Don't get hung up on the carat weight.

4

A clean C.G. mark is nice, but unsigned Giuliano exists. We authenticate based on the enamel application and construction methods.

5

Condition is everything with Victorian enamel. Minor edge wear is normal, but pass on massive enamel restoration.
