Marquette Lake Superior Agate Pendant Copper Replacement Agate The cutting process is slow

The cutting process is slow and responsive to the stone’s internal structure

it formed layered movement patterns that are highly variable and never exactly repeatable

Most material recovered from these field sources contains internal fractures

This ring is built around a copper replacement agate sourced from naturally formed nodules found within amygdaloidal basalt in the Keweenaw Peninsula region of Michigan’s Upper Peninsula

Marquette Lake Superior Agate Pendant Copper Replacement Agate The cutting process is slowThis pendant is set with a Marquette region Lake Superior agate sourced from the Upper Peninsula of Michigan. Lake Superior agates from this region are formed within ancient basalt systems and later redistributed through glacial movement across the Great Lakes. While geologically part of a broader Lake Superior agate system, Upper Peninsula material is less commonly encountered in mainstream lapidary circulation, and quality varies significantly
