Hey!

I bought this geode in Morocco, although not 100% sure that is where it is from, the shop keeper wasnt the most helpful!

It fits together perfectly with the beautiful colours inside and I just wondered if anyone can shed any light on what type of geode this is ?! From picture could a location or source from where it originated be worked out ?!

Many thanks

Sasha

Most probably a quartz geode but may also have some calcite crystals. The colour is probably artificial (these geodes come in a variety of colours) and as far as I know, may be water soluble. Hope that helps out.

Hello,

I do agree with Joseph either quartz and/or calcite dyed geode. An aunt brought me one from Morocco when I was a kid. The dye washed away when put under a water spray.

So if you like it this way keep it untouched as the washed result tends to be less aestheic.

Thank you both very much! It's a very colourful and lovely just a shame it's not 100% natural but I'm no expert so had no idea!

Thank you very much

Hi to everybody!
It's a quartz geode, but the color is artificial. I was presented one of this kind and put it in alcohol. It lost the color and the solution turned purple, meaning the artificial dye was removed from the stone. Moreover, the glued part of the geode came out easily.

A quartz geode from Morocco. Dyed purple to resemble amethyst then dyed with irridescent colors. If the dyed colors were removed, the geode's quartz would be white. Bob
