Bench Cutting
Sourcing unheated rough directly from historic Montana alluvial gravel deposits without chemical disruption.
Sorting raw parcels by specific gravity to isolate stable almandine-pyrope crystal structures.
Inspecting every stone on the Great Falls bench for inclusions, fractures, and optimal optical clarity.
Faceting stones on dedicated laps calibrated to maximize natural refractive indices and carat yield.
Integrity Standard
Unheated stones and rigorous geological transparency rejecting chemical fillers and synthetic substitutes.
Assay Verification
Strict refractive index verification guarantees that each almandine-pyrope maintains its native crystal integrity from rough parcel to finished facet.
