Spinel is a hard vitreous magnesium aluminum oxide that has been used as a gemstone for centuries. The beauty of spinel has caused it to be mistaken for ruby and sapphire in the past. However, spinel deserves to be recognized as a gemstone that is worthy of appreciation in its own right. Spinel occurs in a range of colors, such as rose pink to rich red; lavender to deep violet; light to deep blue, orange, yellow, brown and black.
Spinel occurs with ruby and sapphire, and significant deposits have been found in Cambodia, Myanmar (Burma), Sri Lanka (Ceylon) and Thailand. Other locations where spinel deposits have been found are Afghanistan, Australia, Brazil, Madagascar, Nepal, Nigeria, Tadzhikistan, Tanzania and the USA.
The rarest and most desirable spinel gemstones are vivid ruby-like red, followed by cobalt blue, bright pink and bright orange. Paler colors such as lavender tend to be more affordable. Other popular colors include black spinel, violet-blue, greenish-blue, grayish, mauve, yellow, brown and pink spinel.
Spinel can be seen in faceted shapes such as octagons, trillions, squares, rounds and fancy shapes, such as ovals, pears and cushions. Vividly colored spinel gemstones are rare in sizes over 5 carats. Translucent to opaque stones are often cut en cabochon. Rare star spinel is cut en cabochon to display the asterism.
