These machine cut, or faceted Herkimer Diamonds come from the large clear pieces of broken quartz crystals we find when mining in Herkimer and Montgomery counties, New York, USA. These choice chunks of clear Herkimer quartz are sent to be faceted into familiar traditional gemstone shapes.
Their beauty has exceeded our expectations; we hope your's as well.

• All of the cut Herkimer quartz gemstones are water clear and AA grade. Some of the machine faceted Herkimer photos are representative of the crystal you are purchasing.
  If you are unhappy, in any way, with your order, crystals can be returned, no questions asked. For more information, see our Order Info page.
  
• All machine cut crystals are calibrated for manufactured jewelry settings.
• Some may have a smoky, deep hue or golden hue from associated minerals such as anthraxolite and iron oxide. If this is the case, it will be noted.
• Due to the cost of faceting some of the smaller gems, usually 4 mm and less, a cost of $5.00 per gem is now in effect.
