Colored Cubic Zirconia Stones
Due to its low cost, durability, and close visual likeness to diamond,
synthetic cubic zirconia has remained the most gemologically and
economically important competitor for diamonds since 1976. Platinum or gold cubic zirconia engagement rings for example are an affordable choice for those who like the look of diamond but not the price!
For example, CZ Garnet seeks to imitate the wonderful and luscious red hues of natural garnet. In fact due to its varied and complex chemical composition, natural garnet actually occurs in practically all colors of the spectrum including colorless. Red is chosen for CZ Garnet as it is the most common color in which the gemstone is found, this being Almandine which is the iron/ aluminium version of garnet.
Displayingthe cool tones of a crystal blue lagoon, CZ Aquamarine is a lovely sky blue color that looks beautiful in any setting and jewelry design. Like emerald, aquamarine is a variety of the mineral beryl which is made blue by the presence of what is chemically referred to as iron(II). The (II) is a reference to oxidation level and is important as iron(III) for example results in a golden-yellow beryl.
The yellow colored quartz-based semi-precious gemstone citrine is the inspiration behind the manufacture of CZ Citrine. Natural citrines are rare and are colored by the presence of iron(III). In fact almost all citrine available on the market today is heat-treated amethyst which is also a form of quartz.
Even though the recently synthesised moissanite is also breaking into the diamond imitation market, it does not share the same properties as CZ and is unlikely to overtake it as the most important competitor to simulant diamond. CZ is here to stay and is gaining further ground in the costume jewelry market due to the variety of high grade colors that it can be manufactured in.
