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.

October Birthstones: Tourmaline: This gemstone comes in many colors including the intense violet-to-blue gems particular to Paraíba, Brazil, and similar blues from Africa. A favorite of collectors. Opal: Opal’s microscopic arrays of stacked silica spheres diffract light into a blaze of flashing colors. An opal’s color range and pattern help determine its value.
