Just received these today, was not sure about them honestly, but once I put the tea light in and fire it up, 
WOW, just so beautiful and unique I could not be more happier. Thinking of grabbing 2 more, and maybe for gifts. If your sitting on the fence just jump and purchase them you will not be disappointed, remember these are mother nature art work, were flaws and different markings and what not are the true beauty!!!!!!
