Why Are Imitations of Genuine Gemstone Beads Made?

Gemstone beads are highly sought after for making jewelry due to their color fastness and diverse patterns. Unfortunately, as with most rare natural materials, many counterfeits and imitations exist that the average person may not easily recognize. Some imitations are now so perfect they can only be detected using analytical instruments. So it’s good to be aware of current trends in gemstone counterfeiting.

Cheap imitations of gemstone beads can undermine the true value of natural minerals used to make genuine gemstone beads. For example, various imitations of the mineral Turquoise are sold on the market for just a few crowns, while genuine minerals typically cost 20 to 100 times more—and genuine turquoise beads are hardly even available on the Czech market. Thinking you are buying real Turquoise with its typical qualities and benefits, you may actually end up with Jasper, or dyed Howlite or Magnesite, or even synthetic beads—yet all of these can be sold as "genuine natural Turquoise" on both Czech and global markets.

There are several ways to avoid scams when buying gemstone beads. One is to buy from a trusted seller or well-known brand with a good reputation that regularly verifies its products and monitors suppliers for potential fraud.

It is also important to gather as much information as possible about the beads you plan to purchase so you understand what they should look like and their expected price.

  • For example, you may often come across beautifully pink, blue, red, orange, or green beads labeled as Angelite, but upon researching, you’ll discover that Angelite is a light blue variant of the mineral Anhydrite from Peru, and therefore cannot naturally occur in other colors. Beads offered in other colors—and sometimes even in blue—are actually made from dyed Chalcedony. Since dyed Chalcedony is less attractive than divine Angelite, some sellers market it as pure natural minerals in an unrealistic color spectrum to increase sales.

The Rautis family business is one of the last companies in the world to preserve the traditional technology of blown glass ornaments. The craft includes blowing glass beads, silvering, coloring, painting, cutting, and creative crafting.

In a small village called Poniklá, unique and original beads are made not only for Christmas. These blown products travel across the globe. Thanks to this, the beading craft of the Krkonoše region has been recognized as a UNESCO cultural heritage of humanity. As ambassadors of traditional crafts, Ondra and Standa arranged a personal tour during their business trip to Preciosa.

This gives you the opportunity to look into the entire production process and experience the atmosphere of bead-making that has been part of Krkonoše traditions for more than 150 years. Watch the video to see the exact process—from shaping, blowing, silvering, coloring, cutting to creating artistic decorations.

Is it easy to spot fake mineral beads?

        

With advancing technologies and increasing experience of manufacturers in creating imitations and counterfeits, we can say that it is definitely becoming more difficult, and some fakes are now so perfect that even a gemologist (=an expert in minerals, gemstones, and semi-precious stones) may not be able to detect them 100% of the time. Makers of mineral imitations are imitating natural processes more realistically, and the chemical composition of these counterfeits is also getting closer to that of real minerals. Such perfect fakes can be found, for example, in Citrine, Hematite, or Quartz/Crystal.

Korálky Katlas want to maintain a good reputation with their customers, and therefore regularly check their mineral beads using their own highly sensitive XRF spectrometer and, in case of any doubt, consult one of the best forensic experts and gemologists in the Czech Republic from the Czech Gemological Laboratory - Ing. Jaroslav Jiránek, GIA GG.

They strive to minimize counterfeits in the Czech market and want to share their findings with everyone by writing articles and filming educational videos where they show and compare real and fake minerals so that even beginners and laypeople can recognize the most obvious fakes.

  

  

What types or imitations of mineral beads exist?

    

Mineral beads can be divided by origin or by treatments. More information on how to recognize fake mineral beads, on which foreign online galleries you can find them, or which Czech e-shops we found major errors in identifying mineral beads, can be found on our blog in the category "Getting to Know Minerals". There are already dozens of videos from which you can learn more about individual mineral beads.

Natural Mineral Beads

Mineral beads can be found on the market as completely natural, meaning true minerals in various qualities and grades. Beads are created by cutting the original mineral rock into slices that are slightly larger than the final bead diameter. The slices are then cut into blocks and subsequently into cubes. The cubes are gradually ground into spheres through several steps. Then the beads are polished, holes are drilled into them, they are strung onto cords, and polished again at the end.

Reconstructed Mineral Beads

After natural mineral beads, we may encounter so-called reconstructed minerals. These are most typical for Amber and Turquoise, which are among the most expensive minerals.

  • In the case of Amber, small, hardly usable pieces with a diameter of 1–2 mm are melted and cast into molds. This creates significantly larger products that could not be made from small pieces otherwise. In such cases, sellers should properly indicate that they are made from reconstructed amber—re-melted from natural small pieces. Unfortunately, they are often presented as made from purely natural material.
  • Turquoise cannot be melted and is instead made by gluing smaller pieces together with resin or by filling voids and holes in natural turquoise with resin to make it more aesthetically appealing. Similar techniques can be applied to almost all minerals.

      

   

 

Synthetic Mineral Beads 

You can also find countless synthetic beads on the market that have nothing to do with real mineral beads. These beads are often marketed by sellers as real minerals. What are synthetic (i.e., artificial) mineral beads made of?

  • Synthetic beads are most often made from various chemical substances, which are poured into molds and hardened. Often, these are colored waste mixtures of unknown origin used as fillers combined with resin to resemble natural minerals by touch. On our e-shop, you may encounter so-called Turquenites (= synthetic turquoises), or Opalites (= synthetic opal), which are most commonly sold as genuine Turquoises or Opals on questionable e-shops.
  • Another way of producing synthetic mineral beads is using leftovers from mineral cutting. Grinding dust and chipped pieces are mixed with colored resin to create artificial mineral stone. This stone is then processed like a regular mineral bead. In the end, this results in a semi-natural / semi-synthetic mineral bonded and held together with resin. The purpose is to economically utilize even the waste from minerals, but it becomes problematic if someone sells such a mineral as natural.
  • This category also includes many so-called mixed synthetic gemstone beads made from two or more minerals that do not normally crystallize together in nature. On our e-shop, you’ll find mixed semi-synthetic Regalites with the addition of other minerals.

Gemstone Bead Imitations

Another common issue in the gemstone bead market is the substitution of genuine gemstone beads with cheaper imitations (i.e., lookalikes) made from other minerals.

  • A typical example is the use of the inexpensive mineral Howlite, which is dyed turquoise to imitate Turquoise—known as Sinkiang Turquoise, which is actually just dyed Howlite.
  • A newer technique, only on the market for the past 2–3 years, for imitation fraud involves using the very cheap mineral Chalcedony. Chalcedony is used because it contains microcracks into which dye is injected under pressure. These beads won’t lose their color even in the shower, maintaining vivid tones like natural minerals. Thus, some vendors may offer dyed Chalcedony imitations marketed as genuine Jade, Tourmaline, Beryl, Morganite, Amazonite, Citrine, Rutilated Quartz, Rhodochrosite, Charoite, Kunzite, Peridot, Aquamarine, or Apatite—all of which cost 5–20x more than the original Chalcedony. These imitations are now so convincing that they are difficult to distinguish with the naked eye.

     

 

                

 

        

Annealing of Gemstone Beads

Another modification of gemstone beads is annealing. This involves heating the beads to a higher temperature, where the crystal lattice is rearranged, moving the atoms into more suitable positions in which the mineral then has a more intense color shade.

  • This can be done with minerals that cooled too quickly in nature and thus appear dull in color. It means that it is still an uncolored natural mineral, in which a human-induced process has caused a color enhancement, or even a complete change in bead color. A typical example is heated Citrine, which is created by annealing Amethyst, or various colored variants of Tiger's Eye.

                      

            

        

Waxing of Natural Gemstone Beads

 

Another option to try to sell less vividly colored gemstone beads, is to enhance and simultaneously protect their surface with a thin layer of colored or clear wax.

  • The disadvantage of waxed beads is problems when in contact with hot water, as it can cause the wax to melt off, and in summer the overall higher temperatures and sweat can also affect them.
  • A typical example is waxed Rose Quartz, which may fade almost completely within just a few summer weeks.
  • Some minerals, such as Jasper, or Lava, are waxed with clear wax to ensure durability and increase the beads’ shine.

    How does Korálky Katlas ensure the quality and authenticity of their mineral beads?
    dce

    Replied by: Ondřej Mangl On 25-10-2025 Our company has been on the market for 11 years. In that time we’ve bought gemstone beads from many makers and kept only those that earned the best customer feedback—so we can guarantee quality through experience and careful supplier vetting.

    Eight years ago we introduced a test protocol to verify authenticity. All new goods go through it and we spot-check restocked items. We immerse beads in various solvents to detect surface dyeing (cheap imitations) and perform destructive checks—breaking beads to see whether a colored crust hides glass or a different mineral than declared.

    Six years ago we added our own XRF spectrometer, which we use on every new batch and periodic restocks. XRF lets us non-destructively determine elemental composition to thousandths of a percent. With it, we’ve uncovered hundreds of counterfeits and convincing imitations. We also offer analyses to the public: mineral identification, metal-alloy composition, health safety screening (lead/cadmium), verification of precious-metal alloys (gold, silver), and more.

    Retailers importing from abroad increasingly ask us to confirm suppliers’ claims, and customers request reports or certificates. We provide free reports showing detected elements and percentages—just tell us which purchased item you want it for. Certificates for products we sell cost CZK 50 (€2) for metal alloys and CZK 100 (€4) for minerals, excl. VAT (prices apply only to our own goods).

    Dobrý den, článek je velmi zajímavý. Ale zabýváte se konkténě některými významnými e-shopy, které prodávají minerály? například tady: https://www.manumi.cz/drahe-kameny-a-mineraly? Děkuji

    Replied by: Ondřej Mangl On 06-10-2023 Známe většinu e-shopů, které na českém trhu s minerály obchodují, nicméně díky zákona na nekalé konkurenční praktiky se k nim napřímo vyjadřovat veřejně nesmíme, jelikož jde o naše přímé konkurenty, a pokud bychom někde zveřejňovali jejich prohřešky, tak veškerá finanční škoda a poklesy tržeb by šly právně za naší firmou a museli bychom jim je kompenzovat. Bohužel tak i když na trhu víme o několika stovkách podvodů různých e-shopů na zákazníky, tak je naše firma nesmí a nemůže nikde s přímými odkazy, či výzvami zveřejňovat, či cokoliv na stránkách prodejců komentovat.
