Did You Know? Blue diamonds are the hardest conductors of heat and electricity on Earth. Blue is more rare than pink, but less rare than red, purple and violet. Blue diamonds get their color from boron particles trapped in the crystal lattices while the diamonds are forming. The largest blue diamond weighs 122.52 carats. It was found in June 2014 in the Cullinan Mine in South Africa. The most famous blue diamond is the Hope Diamond housed in the Smithsonian Natural History Museum in Washington DC.

November: Topaz: Colorless topaz treated to blue is a mass-market gem. Fine pink-to-red, purple, or orange gems are one-of-a-kind pieces. Top sources include Ouro Prêto, Brazil, and Russia's Ural Mountains. Citrine: Citrine’s color comes from traces of iron. It’s perhaps the most popular and frequently purchased yellow gemstone and an attractive alternative for topaz as well as for yellow sapphire. Source: https://www.gia.edu.
