Key Characteristics of Authentic Art Deco Jewelry
Understanding these features will help you determine whether a piece is truly from the Art Deco period.
Geometric and Symmetrical Designs
One of the most recognizable characteristics of Art Deco jewelry is its strong geometric design.
Common shapes include:
-
Squares
-
Rectangles
-
Triangles
-
Step patterns
-
Sunburst motifs
Designs were typically symmetrical and highly structured, reflecting the architectural influence of the era.
Platinum Settings
During the Art Deco era, platinum became the preferred metal for high-end jewelry.
Platinum allowed jewelers to create extremely delicate yet durable settings, making it ideal for intricate designs and diamond settings.
Most authentic Art Deco pieces feature:
-
Platinum settings
-
Fine engraving
-
Detailed openwork designs
White gold was also used but was less common in earlier Art Deco pieces.
Intricate Filigree and Milgrain Details
Art Deco jewelers were master craftsmen who paid great attention to detail.
Authentic pieces often feature:
Filigree: delicate lace-like metal patterns
Milgrain: tiny bead-like edges around metal surfaces
These decorative techniques add texture and elegance to vintage pieces and are often difficult to replicate in modern reproductions.
Distinctive Diamond Cuts
Diamonds used during the Art Deco period differ from modern cuts.
Common vintage diamond cuts include:
Old European Cut
A round diamond with larger facets and a softer sparkle than modern brilliant cuts.
Old Mine Cut
A cushion-shaped diamond popular in late Victorian and early Art Deco jewelry.
Emerald Cut
A rectangular step-cut diamond that perfectly complements the geometric style of the Art Deco era.
Asscher Cut
A square step-cut diamond known for its depth and brilliance.
These vintage cuts are a strong indicator that a piece may be authentic.
Gemstones Commonly Used in Art Deco Jewelry
Art Deco jewelry often features bold gemstone combinations that create striking visual contrast.
Popular gemstones include:
-
Diamonds
-
Sapphires
-
Emeralds
-
Rubies
-
Onyx
Black onyx paired with diamonds was particularly popular during this period because it enhanced the geometric aesthetic.
Check the Craftsmanship
Authentic Art Deco jewelry was handcrafted by skilled jewelers.
Signs of genuine craftsmanship include:
-
Fine hand engraving
-
Delicate metalwork
-
Precise stone settings
-
Detailed under-gallery designs
Modern replicas are usually mass-produced and often lack the same level of detail and artistry.
Look for Signs of Age
Because Art Deco jewelry is nearly 100 years old, authentic pieces often show subtle signs of age.
These may include:
-
Light wear on metal edges
-
Slight patina
-
Handcrafted irregularities
However, the piece should still be structurally sound and well preserved.
Check for Hallmarks or Maker’s Marks
Many authentic vintage pieces contain small marks indicating the metal type or jeweler.
Common hallmarks may include:
-
Platinum stamps
-
Maker’s marks
-
European assay marks
While not every Art Deco piece has a visible hallmark, these markings can help confirm authenticity.
