Did you know that you can actually save on costs by making gems? There are plenty of resources that you can choose from including resin, hot glue, nail polish and even modeling clay. These materials aren’t hard to find. There are also numerous videos online that DIY artists post. You can watch them to know how to make those sparkly, quality resin gems.

Aside from the ones we’ve mentioned earlier, you also need a scale, some plastic cups, gloves, acrylic sandpaper, paint, and some wooden sticks. Don’t worry about the bunch of extra materials as you can still use them to make other projects.

Once you have your materials on hand, you can now start making gems. You need to know the shape and the size of the gem so you can find the right silicone mold. Here’s a bit of a good idea:

Are you aware that you can even use the shells of the Kinder Joy eggs as a mold to produce big oval pieces? Icecube molds can also be another choice. There are also tutorials on Facebook on how to use glue to make your own gemstones.

After you’ve figured which mold you’re going for, you can now start shaping your chosen material. If you are using modeling clay like Apoxie Sculpt, make sure the surface of your work area is dry and clean. When using a molder to shape your gems, be sure to check that there is no gap in between your mold box and your form. Adding some plasticine or something similar will get rid of the space. 

To make a perfectly shaped gemstone, put some molding wax or power to cover your form. Placing a stick in the modeling box can also be done for easier removal. If you are using a silicone molder, just follow the super easy instructions that come with the box and then get it covered with what you’ve mixed.

Creating the mold mix will not only challenge your creativity but your patience as well. You will have to wait long hours until it solidifies. This will even take more of your patience because waiting does not guarantee a perfect gem especially if you are just starting to experiment in making your gemstone.

If you want to make it a bit colorful, you can do so by adding colors to the molding box before drying. However, take note that adding too much colour may result in a dark and less transparent gemstone. On the other hand, adding too little color may also yield a not-so-perfect result. Once you’ve achieved the gem you’re pairing with your costume, you can now add it to create that beautiful glitter.

Here is an easy yet fun tutorial you can use in making cheap gems:

  1. Find the flat part of your stone or clear glass gem and paint it with a layer of sparkly nail polish.
  2. After it has dried up, use a dark-colored polish. This will add depth and brilliance to the gem and will show off your creativity. 
  3. Use glass beads that have a flat bottom which is commonly used in aquariums and paint them using black nail polish. 
  4. When these are already semi-dry, scrape it off a bit to create the “clear bits” effect.
  5. Another option is to forgo scraping, and instead, just paint thinly on parts. 
  6. You can fleck your faux opals with different colors as they can be colorful and bright in their original shape.
