 Posted: Aug 24, 2015 14:46 Post subject: Natural Cleaved Corners In Fluorite: Damage Or Not? |
|
|
I know that fluorite likes to naturally cleave in octahedral shapes. With cubic fluorite specimens, I have often seen the corners being naturally cleaved without any traces of contact, dings, or other wear around the cleave.
My question is for a display specimen of cubic fluorite, would this be considered as "damage" by advanced collectors or dealers?
I have seen a specimen that has such a cleaved corner, and it is even covered with tiny chalcopyrite crystals. |

Hi Casimir,
If the fluorite crystal is a true cube, then yes, a cleaved corner is considered damage. If it has a coating of chalcopyrite crystals, it simply means that the corner cleaved in the pocket (not that unusual) and the chalcopyrite was deposited subsequent to this.

I see. The front side of the specimen I am talking about is shaped like a cube, but the back portion is not complete/fuly formed. |
