How To Tell Glass Beads From Plastic, Stone, Or Crystal Beads

Beads can be made from all different materials. Some are glass, plastic, stone, or crystal. How do you tell the difference between them?  There are quite a few ways to decipher between the different materials used and there are plenty of ways to test them. We've done the research so we can let you know how it's done.

One of the easiest ways to tell if a bead is made of glass is by temperature. If it feels cool to the touch, it is most likely glass. Plastic beads will warm up quickly and adapt to room temperature. Other ways to tell if a bead is glass include:

  • Weighing the bead
  • Examining the hole 
  • Determining if it can easily break
  • The heat test
  • Sound

If you're still wondering how best to employ these methods, don't fret. In this guide, we'll go over each technique in more detail, discuss what finishes glass beads have, and we'll even provide you with some glass bead projects. So make sure to keep reading.

Tips For Figuring Out If A Bead Is Made Of Glass

Let's take a look at each method for figuring out what materials a bead is made from. With these nifty tricks, you'll be able to differentiate between various materials.

Weighing The Bead

By weighing the bead, you can tell what material it is made of. Glass, crystal, and stone are going to be much heavier than a plastic bead. You can try feeling it in your hands or by using a jewelry scale. If you know for a fact that one bead is glass, you can go off its weight. Beads are weighed in the metric unit by millimeters. The only ones that are not are seed beads.

Examine the Hole

The hole of the bead also has telltale signs of being glass. A transparent bead is going to have some frosting around the hole and may not feel as smooth as the rest of the bead. It will look cloudy.

Determining If It's Easily Breakable

If you have an extra bead and must know if it is glass, use a hammer. By lightly tapping on it with the hammer, it will break. Glass can break into many different pieces so please be careful when testing this. We suggest placing the bead in a towel and then tapping it.

Heat The Bead

By heating the end of a safety pin with a lighter, you can tell what material the bead is. Heat the pin until red and carefully prick the end of the bead. If the bead starts to melt and the pin goes through it, then it is definitely plastic. Stone, crystal, and glass will not be affected by the hot pin.

Remember, you can also tell if the bead is glass by a simple touch. If it is cool in your hand, it is glass.


You can also test the sound of a bead by bumping them together. If you know for a fact one bead is glass, clink it with another and listen to the sound. Glass beads will make a sound like clinking wine glasses.

Crystal And Stone Beads Versus Glass

Crystal and stone beads are gorgeous beading options. They're relatively heavyweight and stand out in many projects.

It can be difficult to tell the difference between a glass bead and a crystal or stone bead. By rubbing the bead against your teeth, you can feel the surface. A real stone or crystal will feel gritty and textured. A glass bead being rubbed on your teeth will feel smooth and have no imperfections on its surface.

A crystal bead will also create a rainbow prism when it shines. If you tap on a crystal bead, it will have a ring to it with a bit of an echo. If this does not occur, the bead is most likely glass.
