Is a fissure filled ruby real?

The rubies used to create fissure-filled stones are generally of very low quality. This kind of ruby is usually made more porous with an acid treatment. Then it is heated with other materials that make glass when the ruby gets hot enough. The glass fills in pits in the ruby. Therefore, parts of the stone are ruby, but parts are actually glass. Whether you consider this ruby "real" is up to you since parts are ruby, but depending on the size of the fissures that are filled, a significant part of the stone can be glass. The stones can be pretty, but glass does not have the same properties or hardness of a ruby.

Why index of refraction of ruby is less than the index of refraction of diamond?

The index of refraction of a material is related to the speed of light in that material. Ruby has a lower index of refraction than diamond because light travels faster through the ruby compared to diamond. This difference is due to the different arrangement of atoms and the properties of the materials.

A ruby is primarily a light source rather than a reflector. When energized, such as in a laser application, ruby can emit light due to its chromophore properties. However, it can also reflect light to some extent, depending on its cut and surface finish, but its main function is as a light-emitting material in specific contexts.
