Sapphires and rubies are both forms of the mineral corundum but they are different colors.Why?
Most corundum occurs as white, gray, dull blue or dull red crystals. However, a very small amount of corundum has a transparency, purity and color that make it suitable for use as a gemstone. These colorful corundums are among the most popular and valuable gems. Some gem-quality corundum is contaminated with trace amounts of chromium. A very small amount of chromium gives corundum a pink color and larger amounts produces stones that are deep red. These deep red corundums are known as "rubies". Transparent rubies are cut into faceted stones and translucent rubies are cut into cabochon-shaped gemstones. == Corundum that is contaminated with iron or titanium has a blue color. Deep blue corundums are known as "sapphires". When used alone, the word "sapphire" always refers to a deep blue corundum. Gem quality corundum occurs in a wide range of colors, including pink, pale blue, yellow and green. These stones are also known as "sapphires", however, when the color of a sapphire is any color other than deep blue the color of the stone is always used as an preceding adjective. For example: pink sapphire, yellow sapphire, green sapphire. Used alone, the word "sapphire" refers to the deep blue corundum. The color of corundum can be artificially altered by heating or radiation. Sometimes cloudy or translucent stones can be heated to yield brighter color or more transparent stones. When these color treatments are done the stone is supposed to be labeled as "heat treated" when it is presented for sale.
