If all the gold ever mined in the history of the planet was gathered into one cube, it would only measure 20 square yards. Weighing over 200 million pounds, it would be so heavy, it would sink into the earth. Gold is the most malleable metal on the planet, one ounce of pure gold can be drawn into a wire 50 miles long.


Ruby is part of the corundum family. Corundum comes in all colors and is called Sapphire in all colors but red, then it is called a Ruby. But wait, didn't I say that rubies aren't red? That's right, they appear red because they accept every color except red, it reflects red back, rejects it if you wish. That's why we see the red. Also.violets aren't blue, of course, they're violet.


Every diamond on Earth is at least 50 million years old. Diamonds are formed one hundred miles below the Earth's surface. It took 50 million years under 50 million tons of pressure to squeeze a bunch of carbon atoms into the octahedral matrix we call "diamond" (from the ancient Greek adámas meaning unbreakable).


Technically, a diamond is a mineral made of carbon atoms that are crystallized in an isometric form. This means the crystal has the same arrangement in all directions. The rough diamond crystal takes the form called the Octahedron, looking like two pyramids joined at the base. 


Diamond is the the only gemstone made of one element, Carbon. Carbon's chemical designation is "C" and is the same in a brilliant white diamond as it is in graphite or the "lead" in your pencil. While diamonds are isometrically crystallized, graphite is hexagonally crystallized. As human beings, we are one fifth carbon so, perhaps, we are related to diamonds.


The ancient Greeks believed the wearing of amethyst kept you sober.  White gold virtually did not exist until after World War One. Precious metals are non-magnetic. The metals "Alpaca", "German Silver" and "Nickel Silver" have no silver content at all.  The Cullinan Diamond is the largest diamond ever found. Weighing over 3,000 carats. Discovered in South Africa in 1905.
