This pair of earrings features Champagne Aura Quartz crystals, en robed in lead-free solder and attached to 925 silver ear wires just in case of any sensitivities ;) I was fortunate enough to snag some amazing Auras from certified Gemologists at Gemfinders International (www.gemfinders.com) so each will come with a description of the stone from them as well :) Champagne Aura is high grade clear Quartz infused with Gold and Indium creating this amazing aura effect in the stone. This crystal is believed to be good for help bringing our inner ideas and goals to fruition. Manifest your dreams with Champagne Aura! The stone is held together with the Tiffany Technique which I have learned from a stained glass class, but using a lead free solder with a percentage of silver in it. Item shown in the picture is the item you will receive.
