What Is a Rhinestone?

A rhinestone is a man-made imitation of a cut and polished gemstone,
named for quartz pebbles once found along the Rhine River.
Here is where rhinestones came from, how they are made, and what the terms mean.

A rhinestone is a man-made imitation of a cut and polished gemstone. Centuries ago, quartz pebbles with a high lead content were found sparkling along the banks of Europe's Rhine River. These natural stones were highly coveted, and once the supply was depleted, jewelers created an imitation, aptly named the rhinestone.

Today the term describes an imitation gemstone made from crystal, glass, or plastic acrylic. Rhinestones are manufactured in the Czech Republic, Austria, Germany, and parts of Asia.

What are rhinestones made of?

Historically, the highest quality rhinestones were made from leaded crystal: glass with added ingredients, including lead, that make the material easier to cut and better at refracting light. Traditionally it was thought that the higher the lead content, the more brilliant the rhinestone.

That changed. Modern premium crystal is lead-free, and the brilliance now comes from precision cutting, facet count, and foiling rather than lead content. Every crystal brand Rhinestones Unlimited carries is lead-free genuine cut crystal, never molded acrylic or resin.

What else are rhinestones called?

Around the world, rhinestones go by several names:

  • Paste, an older English term for imitation gemstones.
  • Diamante, common in the United Kingdom and Australia.
  • Strass, after Georg Friedrich Strass, one of the jewelers credited with the foiling technique.
  • Crystal, which should only describe a rhinestone actually made of crystal material, not glass or acrylic.

HISTORY

Five centuries of sparkle

Two European regions shaped the modern rhinestone: Northern Bohemia, in what is now the Czech Republic, and the Austrian Tyrol. From the first Bohemian glass kiln to today's precision-cut, lead-free crystal, here is how the rhinestone became what it is.

Timeline

  1. 1548Bohemian glassmaking beginsThe first glass kiln is ignited in Northern Bohemia's Crystal Valley. Over the following centuries, a world-class glassmaking industry grows in the workshops of the Jizera mountains.
  2. Circa 1775The sparkle arrivesJewelers begin coating the back of glass with metal powder, creating a mirror that reflects incoming light and closely imitates a diamond. Credit is debated between Joseph Strasser of Vienna and Georg Friedrich Strass of Alsace. Rhinestones are still handcrafted individually, keeping them accessible only to the wealthy.
  3. 1892Machine cutting is inventedDaniel Swarovski, son of a Bohemian gem cutter, designs an electric machine that cuts crystal far more precisely than was possible by hand. It is the innovation that makes affordable, consistent rhinestones possible.
  4. 1895Swarovski® is foundedDaniel Swarovski establishes his company in Wattens, in the Austrian Alps, where nearby rivers power his patented cutting machines. His stated vision: a diamond for every woman.
  5. 1948Preciosa® is foundedIn the town of Jablonec nad Nisou, 25 independent Bohemian glassmakers unite to establish one manufacturer: Preciosa, inheriting four centuries of Czech glassmaking tradition.
  6. 1956Aurora Borealis changes everythingManfred Swarovski introduces the Aurora Borealis coating, an iridescent finish producing a rainbow effect. Launched with Christian Dior, AB becomes one of the most recognizable finishes in fashion and remains a staple today.
  7. 2012Crystal goes lead-freeLead-free crystal recipes reach the market. Lead had made crystal denser, softer, easier to cut precisely, and better at splitting light into the spectrum. Achieving the same brilliance without it reshaped the industry.
  8. TodayPrecision over leadBrilliance now comes from facet count and cutting precision. Preciosa MAXIMA reflects 264 rays of light through 15 to 18 facets, while 12-facet crystals deliver strong sparkle at a friendlier price.

Where do our rhinestones come from?

Rhinestones Unlimited carries genuine cut crystal from six brands, rooted in the same European traditions described above. Compare all six crystal brands to see how facet count, origin, and price differ, or order a color sample card to see them in hand.

FREQUENTLY ASKED QUESTIONS

Why are they called rhinestones?

They are named for the Rhine River in Europe, where sparkling quartz pebbles were once collected. When the natural supply ran out, jewelers created imitations and kept the name.

What is the difference between a rhinestone and a crystal?

Rhinestone is the broad term for an imitation gemstone, which may be crystal, glass, or acrylic. Crystal describes the material itself and should only be used when the stone is genuinely made of cut crystal.

Do rhinestones still contain lead?

Premium crystal is now lead-free. Lead was traditionally added because it made crystal easier to cut and better at refracting light, but modern lead-free recipes achieve the same brilliance. Every crystal brand we carry is lead-free.

What does AB mean on a rhinestone?

AB stands for Aurora Borealis, an iridescent coating introduced in 1956 that produces a rainbow effect across the surface of the stone. It remains one of the most popular finishes available.

Are more facets better?

Generally yes. More precisely cut facets return more light. Cut quality, foiling, and color consistency matter too, which is why a well-made 12-facet crystal can outperform a poorly cut stone with more facets.
