I don't know much about the crystals and was going to read up on them before I used it. Now here is the strange part. I put the large crystal on the table next to my couch where I sit. The smaller on was on the kitchen table with the intent to carry in my purse. Two days latter I went in to get the large crystal and read up on it but it was not there neither was the one in the kitchen. I looked under the couch behind it, under the table and everywhere else. They have just disappeared. Since I am not familiar with these, I am hoping this is not some kind of bad sign. Do you have an answer to that?
Believe it or not, sometimes crystals disappear or hide for awhile. This is not a bad sign, it just might mean one of the following things: it's not time for you to use the crystal yet and so it is hiding to keep you from having a negative experience; it is needed more elsewhere and will return later; someone else in your household picked it up and forgot to put it back; it wants to hang out with another crystal in your home for awhile.
Usually when this happens, they show up again unexpectedly and often in a place where you know you couldn't have possibly placed it. Pay attention when that happens, because that could be the sign that it's time to use that particular crystal.
I hope this information is helpful to you.
