White zircon does indeed sparkle, often being selected as a substitute for diamonds due to its affordability and brilliance. Its refractive index, a measure of how much light a gem can bend, is relatively high at 1.93-1.98 compared to diamonds' 2.42. Therefore, while white zircon can exhibit a strong sparkle, it doesn't quite match the brilliance of a diamond. The main difference in sparkle is due to diamonds' superior dispersion of light, which gives them their unique fire. Zircon, however, can still offer a convincing diamond-like appearance, especially to the untrained eye, making it a popular choice for jewelry seeking the diamond effect without the associated cost.

In the same way as diamonds. white zirconia has a high luster and brightness. However. zircon has a scintillating effect that is slightly different because it has a high double refraction which bends light in a double pattern. As a result. you can see two surfaces within a zircon. Overall. however. the effect is quite similar to that of a diamond.
Polyvinyl chloride (PVC) is a widely used polymer in the plastics industry, known for its durability, chemical resistance, and versatility. It's a synthetic plastic polymer produced through the polymerization of the vinyl chloride monomer (VCM). PVC is unique due to its ability to be manufactured with different properties, ranging from rigid to flexible, by adjusting the plasticizers during its production process. This adaptability makes it suitable for a variety of applications, including construction materials like pipes and window frames, medical devices, and even as insulation for electrical wires. However, the production and disposal of PVC raise environmental concerns due to the release of toxic chemicals, urging the industry to seek more sustainable practices.
Zircon can be challenging to distinguish from other gemstones. but there are key indicators to keep in mind. Firstly. take note of its hardness - on the Mohs scale. zircon falls between quartz and window glass. Additionally. zircon is recognized for its high refractive index and birefringence. both of which contribute to its sparkling appearance. Another factor to consider is proportion - zircon has a higher weight relative to its size compared to other gemstones. In terms of color. blue is the most popular hue for zircons. but they can also come in green. crimson. yellow. brown. orange or be colorless. And while zircons typically have minimal impurities as a Class 1 gemstone. it's important to watch out for obvious contents that may indicate it's not actually a zircon. Professional gemologists often use specialized tools like gemological microscopy and spectroscopy to more accurately identify secondary characteristics of zircon. It's worth mentioning that cubic zirconia - a man-made diamond substitute - is often mistaken for real zircon due to their shared name and different properties. Ultimately. these are two distinct substances with unique traits.
