1.61ct Teal Missouri River Sapphire, Sourced from a small, family-owned mine outside Helena, MT
Custom Round Brilliant cut by Daniel O’Neil, Alaska
6.9 x 4.4 mm
A decadent Medium-Deep Oceanic Blue, the color of North Atlantic waves! On the beach or in the office, this Round Brilliant cut flashes deep, rich Green/Blues. Like most Unheated Montana Sapphires, this gem will change color with the light and viewing angle, trending between Blue and Green. The rough crystal was visibly dichroic (blue along the C axis and Green on the A/B), and was cut to favor the Bluer “C” . Light rutile silk is present, imparting a soft glow under direct lighting and luscious flashes of color under any lighting condition 🙂 Surface mined from the alluvial gravel deposits of the Missouri River in Montana.
