A nice sized piece of white quartz with a mass of intricate crystalline gold on top. This gold in quartz specimen from the Harvard Open Pit Mine in California is a fantastic piece and it weighs 19 grams (293.2 grains) total weight and measures 1" (26mm) across by 1-1/4" (30mm) high. This would make a wonderful art piece to sit on a desk. It comes certified with a certificate of authenticity. The Harvard Open Pit Mine is now closed and these gold in quartz specimens are getting harder to source.
