How to Tell if a Clear Quartz Crystal Is Real or Fake

Clear quartz is one of the most popular gemstones in the world, loved for its clarity, healing energy, and natural beauty. With demand rising, many fake or lab-grown pieces are being sold online, often marketed as genuine. Knowing how to tell the difference between real and fake quartz will save you money and ensure you get the authentic crystal energy you’re looking for. Here are the most reliable ways to check quartz authenticity and avoid imitations.

Check the Clarity

Natural clear quartz often has tiny inclusions, faint cloudiness, or subtle internal fractures that add depth to the crystal. These natural imperfections are part of its beauty. In contrast, glass imitations or synthetic quartz usually look perfectly flawless and almost “too clear.” A quick way to test is to hold your stone up to the light — real quartz will show depth and natural structures, while glass looks flat and uniform.

Temperature Test

Quartz has a naturally cool feel compared to glass or resin. When you place it against your skin, genuine quartz will feel cold to the touch and stay cool for longer. Glass or plastic warms up quickly and won’t hold the same refreshing chill. This simple test is often one of the quickest ways to spot authenticity.

 

Hardness Scratch Test

Quartz measures 7 on the Mohs hardness scale, meaning it is harder than glass. If you gently scratch a piece of glass with quartz, the quartz should leave a mark. On the other hand, glass or resin imitations will not scratch glass and can often be scratched themselves. This is a reliable test when handled carefully.

 

Bubble Check

Under magnification, fake quartz made from glass often shows tiny air bubbles inside the stone. Natural quartz crystals never contain bubbles — their growth structure forms differently. If you see bubble-like inclusions, it’s a strong sign your quartz is not genuine.

Weight and Density

Quartz has a slightly heavier feel than glass or resin of the same size. When holding a genuine piece, it should feel solid and balanced in your hand. If your crystal feels unusually light, there’s a good chance it’s a fake made from resin or cheap glass.
