Cerridwen Greenleaf, author of The Magic of Crystals & Gems, has written a guide on how to make your very own crystal candles, check it out!

I made candles as a young girl, and that hobby has now grown into a full-blown obsession. A few years ago, it occurred to me that I could have “stained-glass” candles by mixing big crystal chunks into the wax inside the mold. An even easier way to do this is to take a soft beeswax pillar candle and stud the sides and top with crystal pieces that cost just pennies per pound. I save mine from the melted candles and reuse them again and again.
