These crystals and rock gift sets are a bit of a one off here. We ordered five pine incense holders when we were buying our first batch of real stock last month. 
We added a piece of Paolo Santo and a rock or crystal to each one,then tied it with a ribbon or string. 
Crystals and rocks are rough jasper from a rock tumbling mix from nat geo, a beautiful small Scottish quartz Druzy which we collected ourselves from Dumfries and Galloway, a Selenite stick which we always buy when we see it in markets, and/or a small hagstone on the last. 
The ribbons and string can be changed if you want another colour. There are only five of these right now. If you guys, gals, and others like them, then I will find a better source for the incense holders next time but will adjust the price to reflect it. For now, you get at least one cheap hagstones, cheap quartz cluster from Scotland, and a couple of other bits.
Katriona disapproved of the quality of the incense holders and didn't want to sell them at all. However, we figured if we make them into little gift sets and only charge for the cost of the other components, then it might make a nice, thoughtful product that means we don't need to throw anything away.
