A dear friend gave me two small beautiful stones to play with. Without knowing the origin or history of the stones I can tell you this one has warm deep browns and earthy gold colors. I believe the stone is Treasure Mountain Turquoise but, because I can’t guarantee it, this small treasure is selling at the reduced price of $110. Set in sterling silver this beautiful stone hangs on a round rolo shaped Argentium silver chain. Argentium has a little more pure silver than sterling silver, 93.5% silver vs 92.5% of sterling. That small difference helps this Argentium chain shine brighter and resist tarnish more than sterling, all a bonus to you.
