Geologists have shown that earthquakes in underground quartz veins can form small quantities of gold, but not large nuggets. Now, researchers at Monash University in Melbourne, Australia, hypothesize that due to quartz’s piezoelectricity (its ability to develop electrical charge when strained) temblors can generate enough voltage to aggregate gold grains in subterranean fluids into large deposits.

November: Topaz – Colorless topaz that’s been treated to blue is a mass-market gem, but fine pink-to-red, purple, or orange gems are one-of-a-kind. Top sources include Ouro Prêto, Brazil, and Russia’s Ural Mountains. Citrine – This gemstone’s color comes from traces of iron. Citrine is perhaps the most popular and frequently purchased yellow gemstone and an attractive alternative for topaz and yellow sapphire. Source: Gemological Institute of America.
