Diamond Bluff

Diamond Bluff is a small river town on the Mississippi in Pierce County, Wisconsin, named for early settler Monte Diamond and the limestone bluffs above the water, not for any gem diamonds found here. There's a public boat landing on the river, and the surrounding bluffs and floodplain gravel are typical Upper Mississippi Valley terrain. If you're coming here expecting to find diamonds in the ground, don't — no source ties any diamond discovery to this specific location. Wisconsin has produced real glacial diamonds, but the documented finds (the Eagle Diamond and the Theresa Diamond) happened over 200 miles east, in Waukesha and Washington counties. What Diamond Bluff actually offers is river access and the same general Mississippi River gravel that draws collectors up and down this stretch — worth a stop if you're already in the area, not a destination on its own.

Diamond Bluff sits on the Mississippi River in the Town of Diamond Bluff, Pierce County, Wisconsin. The public boat launch is at the intersection of 290th Ave and 985th St, just north of Lock and Dam #3 [2][3].

General river-gravel bar picking (surface, no digging) is the only realistic method here, and it's inference based on the regional geology, not a documented specialty of this spot.

The Diamond Bluff Landing boat launch is a public access point with a crushed-rock ramp; the Town of Diamond Bluff charges a seasonal launch fee (reported around $50) for vehicle and trailer parking [2][3]. Land above the immediate river landing is a mix of private farmland and bluff terrain — UNVERIFIED whether any of it is open to foot access beyond the landing itself. Confirm current rules with the Town of Diamond Bluff before visiting.
