Locality: Montana, U.S.A.
Description: Yogo sapphires were found by accident. In 1895, gold prospector Jake Hoover noticed small blue pebbles caught in his sluice at Yogo Creek in central Montana. He sent them to Tiffany & Co., where gemmologist George F. Kunz identified them as fine sapphires, and Tiffany paid $3,750 for the parcel.
In 1896, sheepherder Jim Ettien traced the stones to their source, a narrow igneous dike cutting across the hills, and staked claims. The rock is an unusual dark igneous rock called ouachitite, a type of lamprophyre that rose from deep in the earth and carried the sapphires up with it. Early mining produced around 400,000 carats a year, and the English-owned mine worked the dike until 1929.
Yogo sapphires are known for an even blue to violet-blue colour that usually needs no heat treatment. Unlike most sapphire deposits, which are in gravels, Yogo stones come straight from their host rock, which also keeps them small and flat.
These are raw Yogo sapphire crystals of about 1 carat each.
In crystal traditions, sapphire is associated with focus, intuition and inner strength.
