    Blue goldstone is man-made glass: a deep navy glass with tiny crystals of copper suspended inside it, which is what makes it glitter like a night sky. It isn't a natural gemstone, and it isn't a knock-off of one either. It's its own material, first developed by glassmakers in Venice in the 1600s and still made today.

    This guide settles so many questions regarding blue goldstone at once. Is “blue sandstone” the same thing? Will it hold up to daily wear? What should a piece cost? And how would you know whether a seller is being straight with you? 

    What Is a Blue Goldstone?

    Blue goldstone is sparkly blue glass. It’s made by melting glass with copper and blue coloring. As the glass cools, tiny copper crystals form inside it. These crystals reflect light, making the glass sparkle. That sparkling effect is called aventurescence.

    How Blue Goldstone Is Invented?

    Goldstone is believed to have been invented in Venice, Italy, in the late 1600s. A glassmaker named Vincenzo Miotti, from a family of glassmakers on the island of Murano, is credited with creating it. His family had special permission from the Doge, who was the ruler of Venice at the time, to make goldstone.

    Later, the Miotti family stopped making it, and the process of making goldstone was eventually revealed. This allowed people to start making goldstone again in the early 1800s.

    You might hear stories that Italian monks accidentally discovered goldstone or that alchemists created it while trying to make real gold. These are interesting tales, but there is no solid evidence to support them. They are better understood as legends.

    These stories are also the reason names such as “monk’s gold” and “monkstone” are sometimes used for goldstone.

    Is Blue Goldstone Real Or Fake?

    Blue goldstone is a man-made glass stone, but that doesn’t mean it is fake. The problem arises when a seller tries to sell it as a natural gemstone.

    “Fake” usually means something made to imitate a natural or genuine material. Blue goldstone is not a natural stone, but it also isn’t an imitation of another gemstone. It is simply a man-made material created for its beautiful blue color and sparkle. So, blue goldstone is man-made, but not fake.

    How Blue Goldstone Is Made?

    As we discussed, the tiny copper crystals are what make blue goldstone look like a starry night sky. But how do these copper crystals get inside the glass? Here’s how it’s done:

    1. The glass is melted, and copper compounds are added to it.

    2. The glass is kept in an environment with very little oxygen. This turns the copper compounds into tiny pieces of metallic copper.

    3. The glass is then cooled slowly. This gives the copper time to gather and form tiny crystals.

    4. As the glass becomes solid, the copper crystals get trapped inside it. The glass is then cut and polished into stones, beads, and other shapes.

    The color of goldstone depends on the color of the glass around the copper crystals. For example, blue goldstone gets its blue color from compounds such as cobalt.

    So, in simple terms, blue glass + tiny copper crystals = blue goldstone. The blue glass creates the dark background, while the copper crystals reflect light and create the beautiful silver-white sparkle that makes it look like a starry night sky.

    What Does Blue Goldstone Symbolise and Mean?

    In crystal healing traditions, goldstone is often called a stone of ambition. Its blue version, blue goldstone, is commonly associated with confidence, clear communication, and the feeling of a starry night sky.

    Some people choose blue goldstone as a personal symbol for progress, graduation, starting a new job, or beginning something new.

    In spiritual practices, blue goldstone is also sometimes associated with the Third Eye, Throat, and Crown Chakras. These are spiritual beliefs, not scientifically proven effects, so it is better to think of the stone as a personal symbol or source of inspiration rather than a universal rule.

    Blue goldstone is not an official birthstone. However, some astrology traditions associate it with zodiac signs such as Sagittarius and Aquarius.

    Is Blue Goldstone Good For Jewelry?

    Blue goldstone has a Mohs hardness of around 5.5–6. This number tells us how well a material can resist scratches from dust, dirt, and other materials.

    For comparison, diamond is the hardest natural mineral, with a Mohs hardness of 10. Quartz has a hardness of around 7, which means quartz can scratch blue goldstone. Even some common dust contains tiny particles of quartz, so everyday exposure can gradually cause scratches.

    Because of this, blue goldstone is not the most durable choice for everyday jewelry, especially for pieces that regularly get knocked or rubbed against other objects.

    However, that doesn't mean you can't wear it as jewelry. Its beautiful sparkle makes it a great choice for occasional or special-occasion pieces, such as a statement ring that you only wear from time to time.

    For everyday wear, pieces like pendants and earrings are better choices because they are less likely to hit or rub against other objects. Blue goldstone may not be the toughest gemstone out there, but its beautiful starry appearance makes it a stone that many people would love to own.

    Blue Goldstone Vs Lapis Lazuli Vs Sodalite

    There are a few gemstones that can look similar to blue goldstone. Two of the most common ones are lapis lazuli and sodalite. They may look similar at first, but they are actually quite different from each other.

    Lapis Lazuli

    Sodalite

    What is it?

    Man-made glass

    Natural rock

    Natural mineral

    Appearance

    Dark blue with silver-white sparkle

    Deep blue with golden flecks and sometimes white areas

    Blue with white lines or patches

    Hardness

    About 5.5–6

    About 5.5–6

    Price

    Usually the cheapest

    Can be more expensive

    Usually affordable

    One interesting thing about these three is that they have similar hardness on the Mohs scale. So, choosing lapis lazuli or sodalite instead of blue goldstone does not necessarily mean you are getting a much harder or more scratch-resistant stone.

    The biggest differences are their origin, appearance, and price. Blue goldstone is man-made glass, while lapis lazuli and sodalite are natural materials.

    What Blue Goldstone Jewelry Costs

    Blue goldstone is made of glass, so the stone itself is not very expensive. But when it is used in jewelry, the price depends on several things, including the stone, metal, craftsmanship, and brand.

    Two pieces of blue goldstone jewelry can look almost identical but have a very different price. For example, one might be set in sterling silver, while the other is made with solid gold. The gold piece could cost hundreds of dollars more simply because of the different metals used.

    So, when buying blue goldstone jewelry, remember that you are often paying more for the metal and craftsmanship than for the blue goldstone itself.

    How to Clean and Care for Blue Goldstone

    Taking care of blue goldstone is pretty simple. Since it is glass, it is more likely to be damaged by heat, sudden temperature changes, and strong impacts than by water.

    Here’s an easy way to clean it:

    1. Mix lukewarm water with a small drop of mild soap.

    2. Gently wipe the stone with a soft cloth or cotton ball. Use a soft brush for small or hard-to-reach areas.

    3. Rinse it with clean, lukewarm water.

    4. Dry it gently with a soft cloth.

    Things to avoid

    • Don't suddenly expose it to very hot or very cold temperatures.

    • Avoid harsh chemicals and strong cleaners.

    • Avoid using ultrasonic or steam cleaners, as they may damage or crack the glass.

    • Store it separately from harder gemstones and metal jewelry that could scratch it.

    • Take rings and bracelets off before working out, gardening, or cleaning to protect them from bumps and scratches.

    Frequently Asked Questions

    Its name comes from the glitter, not the contents. Tiny copper flakes suspended in the glass make it shimmer like gold, which gave it the nickname "goldstone." The original version was a warm reddish-brown.

    The glass is a deep, opaque navy, and in low light it can look almost black. Sellers often describe it as a black crystal with blue sparkles.

    The sparkle isn't a coating, so it can't rub off. It comes from crystals locked inside the glass. What does change over the years is the surface. Scratches dull the polish, and a dull surface makes the glitter look less lively.

    No, though all three glitter. Sunstone is a natural feldspar with tiny hematite and sometimes copper inclusions, and some discount stores have sold goldstone as sunstone. Natural aventurine is a translucent quartzite with platinum mineral inclusions, mostly green but sometimes blue.

    Allergic reactions to jewelry usually come from the metal and not the gemstone. If blue goldstone jewelry is made with hypoallergenic metal, then it won’t cause an allergy.

    It depends on the damage and the setting. Light surface scratches can sometimes be improved by having a jeweler or lapidary re-polish the stone. Chips are harder. Because the material is inexpensive, replacing the stone is often simpler than repairing it.
