Need Help about this "stone"

[BitcoinMarketStore]

This morning went to my shop a customer  that try to sell me the "stone" in photos. I don't know what they are made, but i could say they are really nice (and are over 15 Kg each  ).  I pay, for all you see in photos, 50 € (about 55$). I think to take them in my home because i like this kind of "art" for home , but first, someone could tell me what they are and if they have a real value?

A geologist told me that it is a particular form of gypsum.

A customer offer me 25 € for the littlest .

Somehow, it reminds me of crystal quartz. Not entirely sure to be honest. But it looks like it.

You can find more information on google, simply by googling "Crystal Quartz Stone".

Hope it helps.

Thank you, but Crystal Quartz Stone is the following. Last week i sell the same for about 75 €

both quartz and gypsum are extremely common, and come in may shapes, sizes, and colors, but from the photo it's really hard to tell. My guess would be milk quartz.

My first thought was calcite but I think gypsum is a better shout
