5. (181 ratings) Color. Since CZ are synthetic, they can be made absolutely colorless. Diamonds usually have a yellow or brown tinge, the truly colorless diamonds are very rare. Definition. Cubic zirconia (or CZ), the cubic crystalline form of zirconium dioxide (ZrO2), is a mineral that is widely synthesized for use as a diamond simulant. To test if a diamond is real using heat, grab a drinking glass and fill it with cold water. Use a set of plyers or fireproof gloves to hold the stone. Heat the stone with a lighter for approximately 40 seconds, then drop the stone directly into the cold water. If the stone shatters, it is made of weaker components and is not a real diamond. Just look for a clear stone when buying. 2. Cubic Zirconia Color. In terms of color, cubic zirconia is usually colorless and has the D grading of a diamond. If you know diamonds, then you will know that a D color grade means totally colorless (and therefore more valuable). You can find colored CZ in a range of colors. Cubic Zirconia versus Moissanite versus Diamond (Toughness) According to the comparison table, moissanite is the toughest of the three stones (7.6 metrics) on the official PSI scale of toughness determining gemstones’ ability to withstand. Next is a diamond with a 3.4 toughness and finally cubic zirconia rated at a low 2.4. Cubic zirconia is typically found in a wide range of colors, while lab-grown diamonds are usually clear or near-colorless. Cubic zirconia has a greater specific gravity (5.95) than lab-grown diamonds (3.52). This means that a cubic zirconia stone will feel heavier than a lab-grown diamond of the same size. Both Rhinestone and cubic zirconia (CZ) are popular materials used in jewelry making. They are affordable alternatives to precious gemstones like diamonds, and can be set on metal to create stunning pieces. However, there are some differences between them. 1) Material Rhinestone is a type of imitation gemstone made from high-quality glass or crystal that is coated with a reflective backing to gEjD. Price. The most obvious difference between CZ and diamonds is the price. With cubic zirconia jewellery you can spend anywhere from £7 to £700 depending on the style, designer and metal type. This makes CZ jewellery great for occasional wear or trend-driven pieces. With diamond jewellery, we all know they are one of the most expensive stones The Durability of Moissanite vs Cubic Zirconia. Ranking at a respectable 9.25 on the Mohs scale, moissanite is almost as durable as diamond. This means the stone is impervious to abrasions from nearly every other substance (except diamond). On the other hand, cubic zirconia has an 8.5 Mohs rating, making it less durable than moissanite. With a refractive index ranging from 2.417 to 2.419, which is higher than that of Cubic Zirconia, diamond has a higher brilliance than Cubic Zirconia. When it comes to dispersion, diamond’s is lower (0.044) than Cubic Zirconia ( (0.058 to 0.0600). Therefore, diamond doesn’t sparkle and reflect light as much as CZ does. If you turn both a diamond and a CZ upside down, the bottom of a diamond will give off the entire rainbow of color reflections, whereas CZs usually have more exclusively orange and blue flashes. This is because cubic zirconias and diamonds have different refractive indexes. Just look for a clear stone when buying. 2. Cubic Zirconia Color. In terms of color, cubic zirconia is usually colorless and has the D grading of a diamond. If you know diamonds, then you will know that a D color grade means totally colorless (and therefore more valuable). You can find colored CZ in a range of colors. The only difference between mined diamonds and lab grown diamonds is the origin of the diamond. Grown diamonds and mined diamonds have the exact same physical properties. A cubic zirconia is not a diamond. It is merely a diamond simulant, meaning that it looks similar but not exactly like a diamond. In fact, a cubic zirconia contains zero
