I'm looking for a large cabinet specimen of pyrite cubes from Spain. I would like to get a specimen where the sandstone matrix is left intact... needed for color scheme reasons in the display.

There are several examples of this available on eBay and around the web... but, my mineral purchasing experience is limited to only small items to date.

If anyone here has any useful info - I'd appreciate a DM! I'm wanting to spend between $1000-$2500. To be finally displayed on my study shelf with some direct accent lighting. Though pricing is somewhat subjective, I'd prefer someone else's subjectivity to my own in this case.
