Long before the term “costume jewelry” existed, jewelers were already making glittering, gem-like ornaments out of glass, and doing it with genuine artistic seriousness rather than as a cheap substitute for the real thing. Paste jewelry — glass cut and foiled to imitate faceted gemstones — has a history stretching back to the eighteenth century, and understanding its construction reveals why the best examples remain genuinely desirable objects in their own right, not merely stand-ins for jewelry their owners couldn’t otherwise afford.
What Paste Actually Is
Paste is a lead-rich glass, formulated with a high lead oxide content that increases its refractive index and gives it a brilliance closer to genuine gemstones than ordinary glass can achieve. This is not a modern innovation dressed up in old language — the technique was developed and refined specifically to compete visually with diamonds and colored gemstones at a time when only the wealthy could access the real thing, and skilled paste jewelers were recognized craftspeople in their own right, not simply forgers working in the shadow of fine jewelry.
The critical construction technique that gives good paste its sparkle is foiling: a thin layer of reflective metal foil, applied to the back of the cut glass stone before it is set into its mounting, closed-back style, so that light entering the front of the stone reflects off the foil and returns brightened, mimicking the internal light return of a genuine faceted gem far more convincingly than an unfoiled piece of glass ever could. This is also why closed-back settings, which fully enclose the stone’s back and protect the foil from moisture and tarnish, are strongly preferred by collectors over open-back settings, where the foil (if present at all) is exposed and prone to degrading, dulling, or flaking with age and handling.
Good paste was never meant to trick a jeweler’s loupe. It was meant to catch candlelight across a ballroom, and on that measure, the best pieces still succeed completely.
Georgian and Victorian Paste: The Foundational Era
The Georgian era, roughly the mid-eighteenth century through 1837, produced some of the most technically accomplished paste jewelry ever made, often set in silver to enhance the stones’ brilliance (silver reflects light more effectively than gold, though it also tarnishes and can discolor skin, a tradeoff period jewelers accepted for the visual payoff), and frequently designed in elaborate, gemstone-scale pieces — parures of matching necklace, earrings, and brooch, riviere necklaces of graduated stones, and large stomacher brooches meant to catch the eye at a distance.
Georgian paste is genuinely rare today and commands serious collector prices, not despite being glass but because of the documented skill of period paste cutters, whose faceting quality and closed-back foiling techniques are difficult to replicate convincingly with later manufacturing methods. Victorian paste, produced through the remainder of the nineteenth century, continued the tradition with somewhat more standardized production but maintained the closed-back foiled construction that defines quality paste of this broader era, and remains considerably more accessible to new collectors than Georgian examples while still offering genuine period craftsmanship.
The Rhinestone Revolution
The term “rhinestone” originally referred literally to quartz crystals gathered from the Rhine river, used decoratively before the technique of manufacturing faceted glass imitation stones industrialized in the nineteenth and especially twentieth centuries. What changed the category fundamentally, though, was the development of machine-cut, mass-produced faceted glass stones in the late nineteenth and early twentieth centuries, centered heavily in specific glass-cutting regions of central Europe that developed specialized industrial expertise in precision glass faceting.
This industrialization did something important: it took paste-style glass gem imitation, previously a hand-craft available mainly to the wealthy who could commission fine paste pieces, and made faceted glass “stones” available cheaply and in enormous volume, which is what actually created costume jewelry as a mass-market category in the twentieth century rather than a niche luxury substitute. Rhinestone jewelry from the 1920s through the 1950s reflects this industrial scale directly — manufacturers could set hundreds of precisely matched, machine-cut rhinestones into a single elaborate piece at a price point unthinkable for hand-cut Georgian paste, and design ambition scaled accordingly.
Evaluating Construction Quality
Because rhinestone jewelry spans such an enormous range of quality, from museum-worthy Art Deco pieces to flimsy mass-market costume jewelry, learning to evaluate construction is essential to buying well in this category.
- Prong setting quality — well-made pieces use securely closed prongs that fully cradle each stone without excessive metal showing or stones sitting loosely in their settings; loose or missing prongs are a common and generally repairable condition issue, but excessive looseness across many stones suggests either lower original quality or accumulated wear.
- Stone consistency — high-quality pieces show remarkably uniform color, cut, and size across every stone in a piece, since manufacturers sorted stones carefully by grade before assembly; noticeably mismatched stones within a single piece often indicate later repair with replacement stones that don’t quite match the originals.
- Japanned or antiqued metal finish — many fine rhinestone pieces from the 1920s through 1940s used a blackened (“japanned”) base metal finish specifically to make the stones appear brighter by contrast, and this finish, when original and intact, is a mark of quality manufacturing rather than a flaw; a piece stripped of its original japanning through cleaning has actually lost value, not gained it.
- Foil integrity on closed-back stones — examine closed-back settings for any sign of moisture intrusion, visible through dulling, spotting, or dark patches beneath the stone, which indicates foil degradation that will only worsen and cannot be practically reversed.
Notable Makers and Eras Worth Knowing
Several design eras and manufacturers stand out as particularly significant within rhinestone jewelry history, and recognizing their characteristic styles helps collectors identify quality pieces even when unsigned.
- Art Deco rhinestone jewelry (1920s–1930s) favored geometric line work, contrasting clear and colored stones, and often incorporated genuine design sophistication borrowed directly from fine jewelry of the period, making well-preserved examples highly sought after today.
- 1940s “retro” rhinestone jewelry embraced bolder, more sculptural forms, often in figural and floral motifs, reflecting wartime material constraints on precious metals that pushed designers toward more elaborate base-metal and glass construction.
- 1950s rhinestone jewelry leaned into glamour and scale, with large statement necklaces and brooches designed to coordinate with the era’s structured eveningwear, and represents some of the most abundant and accessibly priced material for new collectors.
- Aurora borealis stones, a coating technique developed in the mid-1950s that gives rhinestones an iridescent, oil-slick rainbow surface effect, marked a genuine technical innovation and remain instantly recognizable and popular with collectors specifically seeking this effect.
Why This Category Rewards Patient Collectors
A well-made rhinestone brooch from the 1940s, built with genuine design intention and careful construction, will outshine a mediocre gemstone piece in almost any light. The material was never really the point — the craft was.
Paste and rhinestone jewelry occupies an unusually forgiving space for new collectors: entry prices remain low relative to fine jewelry, the learning curve rewards careful looking rather than expensive equipment or lab testing, and the design history is rich enough to sustain years of deepening interest. Unlike categories where authentication anxiety dominates the buying experience, paste and rhinestone collecting is refreshingly straightforward about what it is — nobody is trying to convince you the stones are diamonds — which frees collectors to focus entirely on what actually matters: design quality, construction integrity, and the simple, considerable pleasure of well-cut glass catching the light exactly as its makers intended.
Distinguishing Paste from Rhinestone in Practice
New collectors often use “paste” and “rhinestone” interchangeably, but the distinction is worth holding onto even if the trade itself is not always precise about it. Paste, in its strict historical sense, refers to hand-cut lead glass produced primarily before mass industrialization reached glass-stone manufacturing, typically before the late nineteenth century, and set using labor-intensive individual foiling and prong work. Rhinestone, by contrast, generally describes the machine-cut, mass-produced glass stones that industrialization made possible, and the jewelry built around them from the late nineteenth century onward. A collector who understands this distinction can make more informed judgments about a piece’s likely age and rarity from construction details alone, well before checking any maker’s mark.
The practical test most collectors rely on is examining the facet regularity and setting technique together. Hand-cut paste stones, even skillfully cut ones, show subtle irregularities in facet size and angle under magnification that reflect the individual hand of the cutter, while machine-cut rhinestones show near-perfect facet uniformity from stone to stone within the same piece — a level of consistency that simply was not achievable before precision cutting machinery existed. Pair that observation with the setting style, the metal composition, and any maker’s marks present, and a collector can usually place a piece within a reasonably narrow date range without needing to send it anywhere for testing.
Caring for Paste and Rhinestone Pieces
Both categories share a key vulnerability: moisture. Because so much of their brilliance depends on an intact foil backing sealed behind a closed-back setting, exposure to water, perfume, and even prolonged humidity can penetrate tiny gaps around the setting and begin degrading the foil from behind, a form of damage that shows up as dulling or dark spotting and cannot be reversed short of resetting the stone entirely. Collectors who wear these pieces, rather than simply displaying them, are well advised to apply perfume and cosmetics before dressing rather than after, and to store pieces in a dry environment away from the humidity swings that accelerate foil deterioration over time. Treated with this modest care, a well-made paste or rhinestone piece will keep its sparkle for another century just as readily as it kept it for the last one.
Cleaning deserves the same caution as storage. A soft, dry brush and a barely damp cloth handle most surface dust and grime safely; anything approaching submersion, or an ultrasonic jewelry cleaner designed for solid gemstones, risks driving moisture directly into the settings that foiled stones can least afford to absorb. When a piece genuinely needs deeper cleaning — years of accumulated tarnish on the metalwork, for instance — the safer approach is to have a specialist familiar with foiled glass handle it, rather than treating it the way you might a piece of solid gold jewelry with no moisture-sensitive backing to protect. The extra caution costs little and preserves exactly the quality that made the piece worth collecting in the first place.
