Exactly what dean says, I couldn't have put it better myself?
Surely that's the most basic of all crystals to know about?
I have Rose Quartz in my tarot baggies!!, but apart from my vampire one I have hematite for that.
It is indeed the best crystal to use in a romance reading.
Never assume anything.
Depending on one's exposure people can be clueless about anything and everything - and use things in an entirely different way to the accepted cultural "norm".
And though Rose Quartz is designated and accepted as "the love stone" - it may not necessarily be the case depending on the individual IMO.
what does amplifying energies do?
"Amplify" means to make stronger and clearer. So it just means the crystal helps ideas/messages/interpretations to come more readily and easily to the reader.
I have a couple of Clear Quartz crystals that I sometimes like to have on the table when I'm reading.
I think of the property of Quartz as being a general amplifier and helping with "clearer stronger fields and connection" so it really helps me to set the mood and mindset for my readings.
Some of my favourite Tarot decks have crystals living with them in their bags - that I've selected because somehow the crystal - just reminded me of the deck and I just "felt" that it aught to be in there.
As most of my decks are wrapped in silk and then placed inside a bag - I don't get crystal damaging card.
But also mostly - the crystals I choose are smoothly polished. I don't put points and rough ones in.
