15 Costume Jewelry Pieces That Turn Out to Be Worth Real Money

Most people think of costume jewelry as the cheap stuff you grab at the drugstore or inherit from relatives who shopped at department stores. The kind of pieces that turn your skin green or break after a few wears.

But sometimes, hiding in those dusty jewelry boxes and estate sale bins, are pieces that command serious money from collectors and vintage enthusiasts. Not everything that looks inexpensive actually is.

Bakelite Bangles

Bakelite jewelry hits different than other vintage pieces. The weight feels substantial in your hands, and the colors pop with an intensity that modern plastics can’t match.

These early plastic bangles from the 1930s and 1940s sell for hundreds, sometimes thousands of dollars. Collectors pay premium prices for rare colors like deep red or unusual shapes.

The carved pieces bring the most money. You can test for authentic Bakelite by rubbing the piece vigorously with your thumb – real Bakelite gives off a distinct carbolic acid smell when heated by friction.

Miriam Haskell Pieces

Miriam Haskell built her reputation on making costume jewelry that looked better than the real thing, and that attention to detail translates directly into current market value (which explains why her signed pieces routinely sell for four-figure sums at auction). Her work from the 1940s through 1960s combined seed pearls, crystals, and intricate metalwork in ways that made department store customers feel like they were wearing something genuinely precious – and it turns out they were, just not in the way they originally thought.

The construction techniques she used required so much hand labor that modern manufacturers can’t replicate them profitably, making vintage Haskell pieces irreplaceable in ways that drive collectors to pay serious money. And the irony here: many women bought Haskell pieces as affordable alternatives to fine jewelry, only to discover decades later that their “costume” pieces had become more valuable than gold bracelets of equivalent weight.

Eisenberg Original Brooches

Picture this: you’re a jewelry designer in 1930s Chicago, and instead of trying to make your pieces look expensive, you decide to make them actually expensive to produce. That’s exactly what Eisenberg did, and collectors today recognize the difference in every perfectly set stone and hand-finished detail.

These aren’t the mass-produced pins you find at every estate sale. Eisenberg Original pieces (look for that exact marking – later “Eisenberg Ice” pieces are different) used Austrian crystals and sterling silver settings.

The craftsmanship rivals fine jewelry from the same era. Brooches from the 1930s and early 1940s regularly sell for $300 to $1,500, depending on size and complexity.

Signed Schiaparelli Jewelry

Elsa Schiaparelli understood something most costume jewelry makers missed: shock value sells just as well as traditional beauty. Her pieces don’t whisper; they shout, and collectors pay premium prices for that kind of confident design vision.

Schiaparelli jewelry from the 1940s and 1950s commands respect in vintage markets. The designer’s background in haute couture shows in every piece – bold colors, unusual stone combinations, and sculptural designs that look more like wearable art than accessories.

Signed pieces start around $200 and climb quickly for elaborate sets or unusual designs.

Trifari Crown Pieces

Think of Trifari’s crown-marked pieces as the reliable workhorses of collectible costume jewelry – not flashy enough to steal headlines, but built so well that they’ve outlasted most of their contemporaries and developed the kind of quiet reputation that drives steady collector demand. The company earned its reputation through decades of consistent quality rather than dramatic innovation (though their collaboration with Alfred Philippe in the 1930s produced some genuinely groundbreaking designs that collectors still hunt for today).

What sets crown-era Trifari apart from later production isn’t just the superior materials – heavier gold plating, better stone setting techniques, more attention to finishing details – but the fact that these pieces were made when the company still viewed costume jewelry as a craft rather than just a manufacturing process. So when you find a piece marked with that crown, you’re looking at jewelry that was expensive to make even when it was new, which explains why it holds value so stubbornly decades later.

Art Deco Dress Clips

The 1920s and 1930s produced jewelry that understood its own geometry. Art Deco dress clips weren’t trying to imitate nature or historical styles – they were aggressively modern, and that confidence ages well.

These clips were designed to attach to dress necklines or lapels, often sold in matching pairs. The stepped geometric patterns and bold color combinations look as fresh today as they did ninety years ago.

Quality pieces from known makers like Cartier (yes, they made costume jewelry) or Trifari sell for $150 to $800 per pair.

Signed Coro Duettes

Coro figured out something clever in the 1930s: make brooches that could separate into matching dress clips, giving customers two jewelry pieces for the price of one. The mechanism that holds them together has become a selling point for collectors rather than just a practical feature.

Duettes represent some of Coro’s most creative design work. The pieces had to look good both together and apart, which required careful planning and execution.

Collectors particularly value the trembler designs, where parts of the jewelry move with the wearer’s motion. Complete sets in good condition sell for $200 to $600.

Weiss Rhinestone Jewelry

Albert Weiss approached costume jewelry like an engineer solving a problem: how do you make rhinestones stay put and keep sparkling for decades? His solution involved better setting techniques and higher-quality stones than most competitors bothered with, creating pieces that still catch light beautifully today (while cheaper contemporary pieces have lost stones or developed that cloudy, dull look that marks inferior crystals). The attention to structural integrity shows in how well Weiss pieces have survived – brooches and earrings from the 1950s and 1960s often look barely worn, even after decades of regular use.

And Weiss understood color in ways that most costume jewelry makers didn’t: his combinations of stone colors create depth and movement that keeps your eye engaged, rather than the flat, one-note sparkle you get from mass-produced pieces. But what really drives collector demand isn’t just the superior construction or design sense – it’s the fact that Weiss pieces photograph beautifully, making them favorites for vintage fashion shoots and social media, which has introduced his work to younger collectors who might never have discovered it otherwise.

Jomaz Mazer Jewelry

Joseph Mazer built his reputation on a simple principle: if you’re going to make fake jewelry, make it so well that people forget it’s fake. His pieces carry weight, both literally and figuratively.

Jomaz pieces from the 1940s and 1950s used elaborate settings and high-quality crystals that created convincing alternatives to precious jewelry. Mazer’s background in fine jewelry shows in the construction techniques.

Large statement pieces, particularly those with floral or figural designs, bring the highest prices from collectors.

Hollycraft Jewelry

Hollycraft treated costume jewelry like miniature architecture, building each piece with enough structural integrity to last decades while maintaining the kind of ornate detail that makes people stop and stare. Their holiday-themed pieces have developed cult followings among collectors who appreciate the company’s willingness to embrace seasonal kitsch without sacrificing craftsmanship.

The Christmas tree brooches and Easter egg pins represent Hollycraft at its most playful, but the company’s regular production pieces show equal attention to detail. Multi-colored rhinestone sets create jewelry that works as well with modern outfits as it did with 1950s fashions.

Complete parures (matching sets) command the highest prices, often selling for $300 to $800.

Unsigned Art Deco Pieces

Sometimes the most interesting costume jewelry bears no maker’s mark, leaving collectors to judge pieces purely on their design merit and construction quality rather than brand recognition (which can lead to genuine discoveries when someone finds a spectacular unsigned piece that would sell for thousands if it carried the right signature). The Art Deco period produced countless unnamed masterpieces – pieces that demonstrate the same design sophistication and craftsmanship as famous signed jewelry, but without the premium that comes with a recognizable maker’s mark.

These anonymous pieces often represent the work of smaller manufacturers or independent craftspeople who couldn’t afford to establish major brand identities but possessed real skill and artistic vision. And there’s something appealing about owning a beautiful piece of jewelry whose value comes purely from its intrinsic qualities rather than marketing or reputation, like finding a painting by an unknown artist that happens to be genuinely gorgeous.

The challenge, of course, lies in recognizing quality when it isn’t announced by a famous signature – but that’s exactly what makes hunting for unsigned pieces so rewarding for experienced collectors.

McClelland Barclay Pieces

Military service interrupted Barclay’s jewelry career permanently, making his pieces rare in ways that have nothing to do with typical market forces. His work from the 1930s demonstrates sophisticated design sense that collectors recognize immediately.

Barclay specialized in sleek, modern designs that emphasized clean lines and unusual color combinations. His pieces often incorporated enamel work alongside traditional rhinestones and crystals. The limited production period makes any signed Barclay piece valuable, with brooches and dress clips selling for $300 to $1,000.

Pennino Brothers Jewelry

The Pennino Brothers approached costume jewelry with old-world craftsmanship techniques that most manufacturers had abandoned for faster, cheaper production methods, creating pieces that feel substantial and carefully considered in ways that immediately distinguish them from mass-produced alternatives. Their use of sterling silver for settings, combined with high-quality Austrian crystals, produced jewelry that could easily pass for fine pieces at casual glance – and sometimes holds up to closer inspection better than actual precious jewelry from the same era that used lower-grade stones or less careful setting work.

What collectors particularly appreciate about Pennino pieces is the hand-finishing work: edges that are properly polished, settings that hold stones securely after decades of wear, and overall construction that suggests these pieces were made to last rather than just to sell quickly. But perhaps most importantly, Pennino Brothers jewelry photographs beautifully and wears comfortably, making these pieces practical choices for people who actually want to wear vintage jewelry rather than just display it, which helps explain why demand remains strong among both collectors and fashion enthusiasts.

Robert Original Pieces

Robert understood that costume jewelry could be sculptural without being unwearable. His pieces from the 1940s and 1950s balance artistic ambition with practical wearability.

Robert’s work often featured layered construction and dimensional elements that created visual depth. The pieces feel substantial without being heavy, and the designs have aged remarkably well.

Collectors particularly value the figural pieces and elaborate floral designs. Signed Robert pieces typically sell for $150 to $500.

DeMario Jewelry

DeMario specialized in pieces that looked more expensive than they were, using techniques like layered construction and careful color coordination to create jewelry that photographs beautifully and wears elegantly decades after production.

The company’s work from the 1940s through 1960s emphasized sophistication over flash. Multi-strand pearl necklaces with elaborate clasps and matching earring sets represent DeMario at its best.

The attention to proportion and finishing details shows in how well these pieces have maintained their appeal. Complete sets in original condition command premium prices from collectors.

The Treasure Hunt Continues

Costume jewelry collecting operates on different rules than other vintage markets. Brand recognition matters, but so does condition, rarity, and pure aesthetic appeal.

The pieces that command real money today share common characteristics: superior construction, distinctive design, and the kind of presence that makes people notice them across a room. Sometimes the most valuable piece at an estate sale sits in a tangled pile with drugstore jewelry, waiting for someone who recognizes the difference between mass-produced and carefully crafted.

That recognition – and the willingness to dig through boxes of unremarkable pieces to find the exceptional ones – separates casual shoppers from serious collectors who understand that real treasures rarely announce themselves.
