One of the most sought after gemstones from the US is Sapphire.  Montana is one of the largest producers of gem grade Sapphire rough in the world.  Every color of Sapphire imaginable comes from the rivers of Montana! It has been producing Sapphire since the start of the 20th century and still does to this day.  I absolutely love US gems and Montana Sapphires are at the top of the list.  All of the rough produced from Montana is alluvial and obtained through placer mining.  Most of the material found is flat and yields wide flat stones, or small well cut stones.  This gem is absolutely stunning in hand.  It mostly deep blue with hints of green!  The clarity is good and allows for brilliant light return.  Cut at Kosnar Gems, Colorado, USA.  Enjoy!
