Diamond Alternatives

For customers who want the look but not the expense


Diamonds are a girl’s best friend. But when the girl can’t afford or has other reasons for not buying a diamond, she looks for alternatives. Cubic zirconia and created moissanite are often at the top of her shopping list.

The CZ Story

Cubic zirconia dates to 1937, when two German mineralogists discovered the cubic form of zirconium oxide. Soviet scientists learned how to “grow” this mineral in a laboratory in the 1970s, and Swarovski & Co. began producing it for mass consumption in the 1980s. As it became more widely available, CZ quickly became popular with jewelry designers. New developments have led to a sparkling array of CZ in every color imaginable.

Though cubic zirconia looks like diamond, there are some noticeable differences. “CZ has slightly less brilliance than diamond and a hardness of 8.5 on the Mohs scale [diamond is 10],” says David T. Zepeda, sales manager for Fabulous Z, Dallas, TX. “CZ is 75% heavier and, because it’s grown in a controlled environment, a crystal isn’t used if it’s not perfect.”

The Moissanite Story

Moissanite was discovered in 1893 when Nobel-prize-winning scientist Henri Moissan uncovered minute quantities of a new mineral from a meteorite that crashed thousands of years before. In the late 1980s, Cree Research, Durham, NC, developed a way to produce moissanite crystals in a lab. In 1995, a master diamond cutter discovered that when cut properly, created moissanite crystals could look like diamond. Moissanite’s color is comparable to I-J-K colors of diamond, is 9.5 on the Mohs scale and has a refractive index of 2.648-2.691 (diamond is 2.417), dispersion of 0.104 (diamond is 0.044) and specific gravity of 3.21 (diamond is 3.52).
