Cubic zirconia is more brilliant than white sapphire. CZ is almost as durable as a diamond. Although very different in other properties, cubic zirconia and diamond appear similar to a lay person because of their outer appearance and high refractive index. Cubic zirconia simulants are way cheaper than mined diamonds. Most people can’t tell the difference between a well-cut piece of Cubic Zirconia and a diamond. Diamonds also come in colors, called fancies, and these colors are the result of impurities in the crystal. A simulant is any material, natural or created by man, which imitates the appearance of a natural gem whereas a synthetic gem is man-made but must have a natural counterpart that duplicates the chemical, optical, and physical properties of the natural gem. Cubic Zirconia vs Diamond comparison. The synthesized material is hard, flawless and bears great resemblance to a perfect diamond. Cubic zirconia engagement ring by Pescara Jewelry.

What made Cubic Zirconia so popular was the fact that it was so similar to diamonds. In 1937, it was discovered again by two German mineralogists named M. V. Stackelberg and K. Chudoba and was made into a synthetic gemstone by melting zirconium dioxide and yttrium or calcium oxide together. White sapphire and cubic zirconia are both transparent stones. The synthesized material is hard, optically flawless and usually colorless, but may be made in a variety of different colors. Cubic Zirconia Diamond; Hardness: 8.5: 10.0: Density: 5.5 – 5.9: 3.5 – 3.53: Dispersion: 0.058 – 0.066: 0.044: Refractive Index: 2.088 – 2.176: 2.418: Flawless: Always: Rare: Cost : Low: High: Hardness of Cubic Zirconia vs Diamond.

Cubic zirconia often gets compared to diamonds, and for good reason — sparkly cubic zirconia stones can appear quite similar to diamonds. The cup is filled with powdered ingredients and heated by radio frequency induction until the powders melt. The reason for its popularity is its price, which is only a fraction of what a real diamond is worth. Cubic zirconia is the cubic crystalline form of zirconium dioxide. On the Moh’s Scale of Hardness, a diamond is rated at 10. Check this diamond price calculator here. Cubic zirconia is technically a mineral, and the earliest reported findings of cubic zirconia in minerals appeared in the 1930’s. As mentioned earlier, it doesn’t have any carbon diamond bonds in its creation. When viewed with a naked eye, the look of a cubic zirconia resembles a diamond. Cubic zirconia is rated at 8.5. Cubic Zirconia is still thought of as a hard stone, however. Although the cubic zirconia is nowhere as hard as the diamond, it is still harder than most natural gems. Its Mohs scale rating is 8-8.5 out of 10. Faster refraction is why cubic zirconia looks more like a diamond than white sapphire does. These mineral stones were too small to use in jewelry however, and are extremely rare and not commonly found anymore today. 3. This alternative gives an expensive look at a more affordable price. Used by jewelry manufacturers since the 1970s, it is lab created crystalline zirconium dioxide (ZNO2). Moissanite is a diamond simulant containing silicon carbide. Many have wondered what is so special about this beautiful piece of jewelry. What is Cubic Zirconia? Technically, cubic zirconia is cubic crystalline which is a form of zirconium dioxide and only slightly more fragile than a diamond. Le cubic zirconia est très connu en tant que substitut du diamant, grâce à sa dureté et ses magnifiques reflets.
