Montana Sapphires

Green Lake’s collection of ecologically sourced Montana sapphires come from small-scale, low impact mines that sort through alluvial deposits which were once the riverbeds of ancient waterways.

Sapphires discovered in this region of the world come in a wild array of color - from lush peach to deep teal - and it's exceptionally rare to find any two that are alike. From Victorian-era jewelry to contemporary design, sapphires are a favorite gemstone for bridal pieces to last the ages. A gem variety of corundum, sapphire gets its colors from subtle differences in chemical composition, such as varying amounts of iron or titanium. This produces colors that range from deep and inky to lighter tones, with a cool iridescent sparkle.

Sustainable Mining Stewards

Sapphire mining in Montana is an echo of the original gold rush. Today miners search for the very stones that many of their own prospecting ancestors had unwittingly tossed to the wayside, on an 1860's-era search for gold. Today these miners use both sustainable and environmentally friendly systems to protect their communities and legacy.
