Pearl

FAQs

1. What is refractive index and how is it related to IOR?

Refractive index is a measure of how much the speed of light is reduced inside a material compared to outside. The higher the refractive index, the more the light bends or refracts. IOR stands for index of refraction, which is simply another term for refractive index.

2. What are some examples of natural minerals with high IOR?

Diamond, sphalerite, zircon, and rutile are some examples of natural minerals with high IOR.

3. What are some examples of lab-made minerals with high IOR?

Cubic zirconia and synthetic sapphire are some examples of lab-made minerals with high IOR.

4. What is cubic zirconia and how does it compare to diamond?

Cubic zirconia is a lab-made material that is often used as a diamond substitute in jewelry. While it has a high IOR of 2.15 to 2.18, it is not as hard or durable as diamond, which has a refractive index of 2.42.

5. What are some differences between natural and lab-made minerals?

One difference is that natural minerals are formed over millions of years by geological processes, whilelab-made minerals are created in a laboratory in a matter of weeks or months. Another difference is that natural minerals can have unique inclusions and imperfections, while lab-made minerals are created to be as perfect and uniform as possible.

6. What are some common uses for natural minerals with high IOR?

Natural minerals with high IOR, such as diamond, sphalerite, zircon, and rutile, are often used in jewelry and optical lenses.

7. What are some common uses for lab-made minerals with high IOR?

Lab-made minerals with high IOR, such as cubic zirconia and synthetic sapphire, are often used in jewelry, optical lenses, and electronic devices such as watch crystals and smartphone screens.
