Growing DIY Beautiful Purple Crystals at Home!

Purple alum crystal: https://crystalverse-shop.fourthwall.... It's very easy to grow crystals at home, and purple alum is one of my favorite crystals to grow. It's actually made of a combination of two types of alum. White (potassium alum) and purple (chrome alum). The higher the ratio of chrome alum to potassium alum, the darker the crystal. If you like these crystals and want to buy them or surprise someone with a gift, you can find them at the link above.
