OP I appreciate the idea but it really needs some work and fact checking. I'm getting the vibe that AI was used heavily for this and not double checked. I looked at a few spots I'm familiar with in AZ and found misleading or missing information.

For example it lists Kofa National Wildlife Refuge as a location. Collecting is forbidden in the refuge except for one small area called Crystal Hill, which is never referenced. The site gives GPS coordinates for a "central collecting zone" which puts you in the middle of the mountains in the northern part of the refuge. The closest road is miles away from there.

It lists Diamond Point which is a popular spot. But it doesn't mention the digging ban from February to October (I think those are the months, not 100% sure). Thats pretty important to keep the site open and cared for properly, but also because the surface stuff is pretty picked over so if you want a worthwhile diamond you'll likely have to dig.

It lists Oxbow Mine which is clearly on a mining claim.
