This was a pretty simple idea.  I bought a bag of rocks at the Dollar Tree for $1.00 and the glass for $1.00 and a package of candles for $1.00.  Pour some rocks or stones in the bottom and place your candle on top.  A pretty simple yet pretty cool candle holder.  And I've plenty of rocks and candles left to make several more.  You can even use a small drinking glass or other type holder.
