Title: What is the formation inside this geode?
Post by: mzj9k021 on 27/07/2017 03:02:05

I bought this geode then split it and the seller tried to take it back off me, I had to be quite forceful to remind him that I had already paid for it, he tried to offer me multiple geodes to keep it and it took alot of negotiation to keep it, I have had it for a number of years always wondering what it was, thought I would try to identify the different minerals finally.

It looks like amethyst geode . If it is don't give up the day-job: they're plentiful and consequently inexpensive ...

The top picture shows what appear to be two additional crystalline minerals (white and dark brown). I can't tell from the picture what they are, but the crystal shape doesn't look like quartz (amethyst etc.) to me. It could be that one (or both) of these minerals is more valuable than amethyst. It could also be that the inclusion makes the geode more unusual (rarer), and the dealer thought it might attract a higher price than the typical geode.

I just like the look of it, I didnt think that it would be my ticket to the high life, but it does look good on display, i really appreciate the input on it.
That is of course until the "top hat" crystal is identified as an ultra rare diamond or mineral brought to earth on a meteorite from distant planet and it sells for millions of dollars.;)
