This is a one of a kind free form faceted gemstone. Threadlike golden rutile in light smokey Quartz. This piece is approximately 42 carats; or 9.2 grams. Ready to be set into a designer piece of jewelry, or like me just keep loose on display and stare at. I have taken pictures of it outdoors under natural light, in direct sunlight and indoors under artificial light from many angles so the buyer can see how thick it is and the sides.
