Introduction
Art Deco jewelry isn't defined by geometric lines and architectural design alone—its visual impact also comes from the carefully selected stones that compose it. Chosen for their brilliance, contrast, or symbolism, the stones used between 1920 and 1935 reflect a bold and rigorous aesthetic.
Deep onyx, mysterious jade, radiant diamonds—each gem contributes to the creation of this inimitable style. Here’s a closer look at the most iconic gemstones in Art Deco jewelry.
Diamonds: Brilliance and Geometric Perfection
It’s impossible to talk about Art Deco jewelry without mentioning diamonds. But not just any cut will do.
-
Baguette cut: long and linear, it enhances the structure of the piece.
-
Emerald cut: rectangular with step facets—clean, bold, and elegant.
-
Marquise or Asscher cuts: precise symmetry and sharp reflections.
In Art Deco pieces, diamonds are used graphically—arranged in rows, framing a central stone, or forming mosaic patterns. Their bright white brilliance pairs perfectly with platinum or white gold and plays beautifully with contrasting materials.
Onyx: Deep Black, Bold Design
The intense black of onyx is a signature of the Art Deco aesthetic. It’s used to create striking contrast with diamonds or mother-of-pearl, giving visual structure to the design.
-
Frequently cut into baguettes, triangles, or disks.
-
Used as background, border, or even centerpiece.
-
Accentuates geometry and adds a modern, edgy touch.
Onyx also symbolizes refined simplicity—an essential element of the era’s minimalist chic.
Jade: Exoticism and Elegance
A symbol of Asian spirituality, jade found its way into Art Deco jewelry thanks to the strong Oriental influences of the 1920s.
-
Ranges from soft green to deep forest hues, and sometimes white or lavender.
-
Adds an organic, gentle contrast to structured compositions.
-
Often paired with onyx or diamonds for dramatic effect.
Common in pendants, earrings, and bracelets, jade evokes wisdom, serenity, and mystery.
Mother-of-Pearl: Softness and Light
Derived from shells, mother-of-pearl was prized for its natural iridescence and soft luminosity. It softened the sharp geometry of Art Deco compositions.
-
Subtly reflects light for a delicate shimmer.
-
Used in background layers or stylized floral motifs.
-
Combines beautifully with white gold and platinum.
It represents femininity and refinement within highly structured designs.
Coral: Boldness and Sensuality
Red or pink coral was commonly used at the time, though today it’s rare and highly regulated. It brought a warm accent to compositions dominated by black and white.
-
Vivid yet natural in tone.
-
Popular in brooches and pendants.
-
Evokes femininity and exotic elegance.
Today, ethical alternatives like colored glass or dyed natural resins replicate its effect without endangering marine ecosystems.
Emerald, Ruby, and Sapphire: The Classic Trio
These three gemstones were cornerstones of high-end Art Deco creations:
-
Emerald: deep green, emerald cut, symbol of renewal and balance.
-
Ruby: intense red, evoking passion, vitality, and luxury.
-
Sapphire: rich blue, suggesting calm and sophistication.
Used alone or paired with diamonds, they created sumptuous pieces, often designed by prestigious jewelry houses.
Lesser-Known but Distinctive Stones
-
Lapis lazuli: a deep royal blue sprinkled with golden flecks.
-
Rock crystal: often carved or polished into cabochons.
-
Turquoise: bright blue, used in Egyptian- or Native American–inspired designs.
These secondary stones added variety to more playful or exotic Art Deco pieces.
The Symbolism Behind the Stones
Each gemstone carried meaning—something designers of the era paid close attention to:
-
Diamond = purity, commitment, modernity
-
Onyx = protection, mystery, strength
-
Jade = wisdom, inner peace
-
Emerald = renewal, clarity
-
Ruby = passion, life force
This symbolism gave jewelry a personal resonance—something that still appeals to collectors and buyers today.
