Here is a quick way to create resin gems for your cosplay.
1) Buy clear cabochons in the size you want
2) Use metallic nail paint and paint a few layers. Make sure you use metallic paint as I’ve experimented with a few others and they do not provide the varying color effects.
The last picture compares ones painted with metallic paints vs ones painted with regular nail paints. Bottom left has metallic gems. Ones with glitter and ones without. The upper right has gems painted with normal nail paint except for the yellow gem which was painted with metallic paint as well. See the difference?
3) Glue polystyrene, silver scrapbook paper, or aluminum foil for backing so your paint doesn’t chip or tear away. Most use hot glue but I just use a very thin layer of Sobo (fabric/craft glue) and it does the trick. Enjoy!
