    This is an lovely gemstone and a true US treasure. The finest gem grade Rhodochrosite comes from the Sweet Home mine in Colorado. There are several other localities for fine quality Rhodochrosite, but none are as exceptional nor are they as productive as the Sweet Home Mine. The mine has been closed for over 14 years now, and the portal was buried. Recently, there has been new production from Alma, but nothing has hit the market just yet. The market has dearly missed all of the quality gem grade Rhodo since the mine’s closing, and now the price of any specimens or gems has sky rocketed. This stone was custom faceted in the US. The color is a lovely pink that is so iconic of the Sweet Home material. The Sweet Home Mine, is the reason that Rhodochrosite is the Colorado state mineral, and it is absolutely well merited. The rough for this stone was mined in 1978 by Richard A. Kosnar (Owner, Mine Hand) and David L. Bergman (Mine Forman, Lead Miner). The material that was mined through that year was some of the finest Rhodo to be found of all time. The mine was reopened in the 1990’s by Bryan Lees, the owner and operator of Collector’s Edge. The mine saw its greatest production in history, and some truly exceptional material came out over the next 10 years. Sadly, most of that material is gone and very little of the major crystals were ever cut into gemstones. Enjoy this American treasure! This stone was faceted by Brett Kosnar of Kosnar Gem Co, September 2018.
