The precision of these natural formations gives the stone an almost watchful presence

but even at this level it remains unpredictable to work with

the cabochon is shaped slowly and deliberately—this particular size requires approximately 60–90 minutes of continuous cutting and refinement due to the stone’s brittleness

Marquette Lake Superior Agate Ring Copper Replacement Agate Others capture patternThis material is collected from a very limited number of shoreline locations in the Upper Peninsula region of Lake Superior. One of the primary collecting areas has been lost to shoreline erosion, and another is now seasonally buried under shifting sand, significantly reducing reliable access to fresh material. As a result, the usable yield from field recovery is extremely low. The majority of nodules found in these areas are not suitable for lapidary
