Jewelry Styles & Modern Revival Styles


Dating from: 1800s - 1900

Mimicked the Queen’s jewelry – from snake pieces to orange blossoms to mourning jewelry. Often in real gold and silver; technology made jewelry more accessible to the masses.


Dating from: 1901-1914

Jewelry and style was light and airy and feminine – think swirls and ornate lines. Technology was allowing for more detailed intricate pieces. If a piece has a platinum or ornate frame you can usually assume it is Edwardian or earlier.

Art Nouveau

Dating from: 1895 - 1915

Spans both Victorian and Edwardian eras, focused on more organic elements such as insects, flowers and the female form. Jewelry and accessories featuring “risque” nude females proliferated this era.

Art Deco

Dating from: 1919 - 1939

The most defining characteristic of the Deco period was geometric shapes – rectangles, triangles, octagons – representing the modern and streamlined spirit of the era.

Retro Mid Century

Dating from: 1935-1950s

Expressive and innovative costume jewelry was the hallmark here; it was feminine and cost-conscious during the war years. Popular motifs were embellished brooches, statement bracelets and necklaces, gemstone pendants, birds, ballerinas and nature.

Mid Century

1950s - 1960s

Salvador Dali, Georges Braque, Pablo Picasso and Jean Cocteau were among the artists who inspired American Studio Jewelers to create “Jewelry as Art” or “Wearable Art. Drawing their inspiration from the philosophies of Bauhaus, Dadaism, Surrealism, Isomorphism and Cubism, the modernist‘s work was characterized by abstract and non-objective form. Creations by Mid-Century American Studio Jewelers were often one-of-a-kind and totally hand fabricated.


1960s embraced bold designs mixed with the femininity of the 1950s. Large hoop earrings, medallion necklaces, bangle bracelets, Victorian “Revival” pieces mimicking the queen’s pieces at costume level, Egyptian Revival, chunky chains, love beads and peace signs were de rigueur.


1970s were a time of increased connection with nature, apparent in the jewelry materials of the day. Bone, shell, wood, stone were common in this natural “hippie” time! Turquoise made its first huge insurgence and the most common metal was gold – used in chunky bracelets, rings, chains and layering necklaces.


1980s were characterized by chunky gold jewelry, plastics, hoop earrings. However, more traditional costume jewelry like pearls and rhinestone brooches were still embraced – often in much bigger sizes.


1990s were a time of bold and eclectic pieces like chokers, bangle bracelets and hoop earrings. At the same time, more delicate pendant necklaces and softer lines were also popular – a throwback to the Edwardian/Nouveau eras.

Victorian Revival


Victorian Revival (1960s, 1970s) Jewelry copied the chunky, Egyptian, big stones and ornate frames of the original, using plastics and glass rather than fine stones.

Edwardian Revival

Full of beautiful details and very delicate. This period marked the transition from Victorian jewelry to more modern jewelry.

Art Nouveau Revival


Jewelry used delicate scrolls, leaves, ribbon bows, hearts, circles, swooping swags (or garlands as they were later called) to mimic the romance of the original period.

Art Deco Revival

Featuring the geometry and straight lines of the original Deco, often using glass or similar lucite stones to mimic the glass.

Egyptian Revival

Egyptian revival jewelry (1920s and then again 1960s/70s) was a renewed interest in ancient Egyptian jewelry styles. Featuring hieroglyphics, scarabs, reeds and lotus flowers, Egyptian revival jewelry was spurred by the discovery of ancient Egyptian tombs, notably the tomb of Tutankhamun in 1922.

Testing Your Jewelry Content

Presidium Tester

Presidium Tester: Gem testers are available in all varieties – some only test for diamonds, etc, but the majority of them use thermal wands to detect the heat in a stone to tell you if it is real or glass.

Acid Tests

Acid Tests: Acid tests include a testing stone and acids that react to Sterling, and Golds of different karats. Used by sellers and jewelers everywhere. Haven’t changed much in the last 20 years. You simply scratch the item on the stone and see which acid reacts.

Bakelite Tests

Bakelite Test: Simichrome is actually a benign Jewelry Polish that just happens to change color when it reacts with the chemicals in Bakelite. You just take a Qtip with a bit of Simichrome on it and gently rub the surface of the item. Bakelite will turn the pinkish Simichrome to a rust color.
