Rocks are made from mineral. Some minerals can grow in large beautiful crystals. Gemstones are an example of this. Take the diamond for example. One large crystal of just carbon. Graphite is also made of just carbon, so why are they different? It all depends on the crystal structure, how the atoms are bonded. Some times you'll get replacements for diamonds, like the cubic zirconium, or a white sapphire. A more recent replacement is moissanite. It was found in the meteroite that landed in what is now know as Meteor Crater, Arizona. Fragments found in Diablo Canyon by Henry Moissan in 1893 were studied and determined to be made of silicon carbide, earned him the name of the new mineral. The company Charles and Coalvard began processing the mineral for sale in the late 20th century. It's fire and brilliance out wits the diamonds glow. Want to see it for yourself? The moissanite also wins at heat resistance. When put in to a furnace at 1100 degrees celcius, the diamond will vaporize and the moissanite will keep it's true brilliance. It is also much more rare to get than diamond and is 10 times cheaper. This is the kind of jewel that I would recommend.
