Types of Rubies

Popular gemstones, rubies are fiery red in color, a symbol of love and passion. Rubies are in essence, red sapphires – both rubies and sapphires are made of the mineral corundum. A ruby's red color comes from the presence of small amounts of chromium in the corundum (aluminum oxide). Intense, red-colored rubies exhibiting no trace of other colors are amongst the most sought-after stones. Top quality rubies, rare and breathtaking, command an even greater price than diamonds in the marketplace.

Potential buyers can choose from a variety of ruby types. Types are defined by geographical location, color and cut. A unique form – the star ruby – reflects light to reveal a six or twelve-ray star pattern or "asterism." Jewelers cut these rubies into smooth domes or cabochons to reveal their magnificent star patterns. Experts also distinguish types of rubies by their region of origin. Red rubies are native to Burma and lighter rubies originate in Sri Lanka, while Africa is famous for purple-red rubies.

Like most gemstones, rubies can be synthetically produced. Distinguishing real gems from synthetic rubies and red peridot is extremely difficult. It is important, therefore, always to purchase rubies from a reputed dealer.
