I made these faceted DIY resin magnets awhile ago, thinking they might look like coal for stockings if I made them black? But my mold is definitely “gem” shaped and they ended up looking more glam. I still think they’d made a fun DIY stocking stuffer though, so I wanted to share – plus it’s a blast from the past seeing the kitchen with turquoise cabinets and these shelves! I wasn’t kidding when I said I made these aaawwwhiiile ago.
Supplies for DIY Resin Magnets:
- 3.5 oz clear casting resin
- 14 drops colorant (you can use acrylic, resin tint, alcohol ink)
- 8-10 tbsp black glitter
- Gem shaped silicone mold (but this one might look more coal-shaped)
- Thin and strong magnets (mine are from Michael’s, these are similar)
- 2-part epoxy
- Plastic cup for mixing
- Wooden stir stick
- Safety glasses, gloves, apron, drop cloth to protect work surface
- Cutting board or solid surface (to set silicone mold on for stability)
Below is a photo of the exact brand of resin I used. The above measurements make 12 magnets in my gem shaped silicone mold (edit: mine sold out so here is a nearly identical one). I found another silicone mold that is less gem shaped and more rock shaped and that might make a more realistic coal shaped magnet.
How to Make DIY Resin Magnets:
Making resin magnets ended up being really easy – but SO stinky! If you can, do this project outside or in a well ventilated garage (just read the instructions to make sure the temperature is correct). Making resin magnets is also potentially messy. I didn’t spill any, but if you do, apparently it’s really, really difficult to clean up. So protect your work surface, and put on some crummy clothes, safety glasses, gloves – the whole, super chic DIYer ensemble, haha.
First place the silicone mold on a hard, flat surface (like a cutting board) because it will make it easier to move your project somewhere else to let it set. Mix the casting resin and catalyst (sold together, but separated) in a plastic mixing cup (grab something from the garbage/recycling) with a wooden stir stick. The can will have the instructions so follow them to the letter! Then you can stir in glitter and a little colorant (I used black) and pour it carefully into the silicone mold. I let it set for a bit in place and then carried it to the fish room, so it could fully set undisturbed. Once it had set fully (it took a few days), I mixed up some 2-part epoxy and affixed a strong, flat magnet to the back:
These gem shaped DIY resin magnets turned out so adorable! Even if they don’t look like coal for stockings. But of course I love a gem shaped anything (frankly, all rocks and minerals). I have a LOT of resin left, which is perfect because I’d like to try doing some marbled acrylic pouring and some other casting projects. This was my first attempt and I just followed the instructions on the can – but added my own sparkle. There are some imperfections in my casting, so I’m going to keep experimenting, but I wanted to share so that you could see that even a resin-newbie can create something cute!
