What if You HAD to Choose JUST ONE?

What if you had to choose just one crystal?  

First of all, I hope I never do.  I love crystals in all their variety, colors, inclusions, weight, and even the variety within each type of crystal.  Add to that the carvings and varied shapes... well, I think you get the picture.  I don't think I could choose just one.

But, since I've asked the question, I'll see if I can answer it.

If I could choose only one, I would lean on functionality and go with a crystal that can be used for all chakras.  That narrows the field a bit, but leaves a lot of options.  Clear crystals typically benefit all chakras.  We're not talking about just Clear Quartz.  There's Icelandic Spar (Clear Calcite), Clear Topaz, and Lemurian Quartz to name a few clear ones.

For those that are not clear, there's Sichuan Quartz, Serpentine, Seraphinite, Scapolite, Rutilated Quartz, Stibnite, Magnetite, and more.

But the questions is, if I had to pick just one.... I would choose Icelandic Spar (Clear Calcite, also called Optical Calcite).  My experience with this one is intense.  This is not to say that wouldn't change my mind.  If I come across a crystal that is particularly powerful for me, I'll use it in meditations and healing often.  That's my answer:  Icelandic Spar... for now.

So, how about you?  Which crystal would you choose if there could be only ONE?  What's a favorite of yours, tell us and tell us why?
