chain laces through a silvery pyramid top. 

because they are made of natural crystals, each pendant is unique (slight differences in length, opacity, colors) 

and there may be natural flaws in the stones, such as little bits of other minerals within them, or little divots or cracks.  

 necklace is about 20" long. pendant is about 1.25 to 1.5" long. new in baggie.

I also have the same pendulum necklace, in amethyst and in opalite, in other listings in my ebay store.
