What is Cubic Zirconia?

'Diamonds are a girl's best friend' as you know!
Well the good news is that synthetic diamons, such as cubic zirconia, don't lose their shape either and everyone can afford one!
Cubic zirconia is a synthetic gemstone. But the cost of cubic zirconia jewlery is just a fraction of the cost of jewelry containing real diamonds.Even jewellers can't tell the difference between a cubic zirconia and a real diamond with the naked eye! Cubic Zirconia is a high quality synthetic gemstone which imitates the appearance of diamond and is usually made in a lab. Cubic zirconia is zirconium oxide(ZrO2) a mineral that is extremely rare in nature but easily syntheized. Synthesized Cubic Zirconia (or CZ) is hard, optically flawless and can be made in a varietiy of different colors.

The advantages of CZ:

Cost- the cost of cubic zirconia is roughly a tenth of the price of natural diamonds.

Appearance- cubic zirconia is so optically close to diamond that even jewellers can't tell the difference between a cubic zirconia and a real diamond with the naked eye--jewelers use a loupe to the the difference.

Clarity - Cubic zirconia is equivalent to the highest grade(F) on the Diamond Clarity Chart. Grade F diamonds mean they have no internal or exteral flaws, very rare and expensive.

Inclusions/Flaws - Cubic zirconia is virtually flawless whereas most diamonds have internal inclusions or external blemishes.

Color - Cubic zirconia can be made entirely colorless or white, equivalent to a perfect "D" on the color grading scale of diamond.

Colored cubic zirconia-natural colored diamonds are extremely rare and espensive but synthetic gemstones can be made in a variety of different colors.

Fluorescence - An undesirable hazy effect. The fluoresence of diamonds or cubic zirconia is not usually noticed by the naked eye but can be seen under ultraviolet lighting at dance clubes and jewelry stores. Under ultraviolet lighting cubic zirconia typically fluoresces a yellow, greenish yellow or beige color.

Hardness - Hardness denotes resistance to scratching as opposed to toughness which relates to the ability to resist breakage from falls or impacts. Cubic zirconia is much harder than most natural gems at about 8.5 on the Moh's scale, however it is nowhere near as hard as a diamond at about 10 on the Mohs scale.

Weight and Size - Cubic zircnoia is about 75% heavier than diamond and meansured in millimetres, referring to the diameter as opposed to carats. A cubic zirconia will weigh about 1.7 times more than a diamond of equivalent size. A 6.5mm cubic zirconia is equal in size to a one -carat diamond but actually weights about 1.75 carats

Cubic Zirconia vs Diamond:
Jewelry containing synthetic gemstones like cubic zirconia are not a good investment as they do not hold their price. Cubic zirconia has slightly less sparkle than diamonds. Sparkle is a meansure of the light reflected out by a diamond as it is viewed from different angles.Cubic zirconia has more 'fire' or brilliance producing a more synthetic effect.

Hardness-Diamonds are harder than cubic zirconia which is 8.5 on the Mohs scale compared to a diamond at about 10.0 on the Mohs scale

Toughness- Cubic zirconia is more brittle than diamond and has less ability to resist breakage from falls or impacts.

Rarity- Cubic zirconia is not rare and can be made quickly and in vast quanities, whereas natural diamonds take millioins of years to from.

Many people see expensive jewelry as frivolous expense and are happy with a less costly option that looks every bit as goog as the real thing. Others see buying a diamond as an investment which is given as a symbolic gesture. The choice is yours!
