The chemical composition of ruby is aluminum oxide (Al 2 O3). Its specific gravity is 3.99 to 4.00 and refractive index range is 1.760-1.768 to 1.770-1.779. Ruby's hardness on Mohs scale is 9. It's the next hardest mineral after diamond.

Depends on the size, redness, and if it is a star ruby.

The most important factor when determining a ruby's value is it's color. Garnet-like, dark rubies and light colored, almost pink looking rubies, offer the most value. Large rubies of a high quality are extremely rare and the most prized. Clarity is also a very important factor, "crystal clear" is the ideal, meaning you should be able to see through the ruby without hindrance. A cut ruby should have good symmetry and shine. Look out for such words as "created" or "cultured", they mean synthetic, or man made. If a jeweler says the ruby is natural, get it in writing.
No, ruby is not magnetic because it does not contain any magnetic properties or elements within its structure. Ruby is a type of corundum that is composed of aluminum oxide with trace amounts of chromium responsible for its red color.
Ruby is composed of aluminum oxide with trace amounts of chromium, which give it its red color. It has a hardness of 9 on the Mohs scale, making it a durable gemstone suitable for everyday wear. Ruby's vibrant red color is due to the presence of the element chromium in its crystal structure.
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.

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.
Yes, you can wear ruby and onyx together. Both gemstones have distinct properties and meanings; ruby symbolizes passion and vitality, while onyx provides protection and grounding. Their contrasting colors—ruby's vibrant red and onyx's deep black—can create a striking visual combination in jewelry. Ultimately, personal preference and style should guide your choice in wearing them together.
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.

True. Rubies are used in certain types of lasers, specifically ruby lasers, which were among the first lasers developed. These lasers utilize synthetic ruby crystals, which emit red light when stimulated by a flash of light. The unique properties of ruby make it suitable for applications in various fields, including medicine and telecommunications.
The ruby is at The Stage but you can only get it if the play is Ruby and the Ruby.
The braille next to the ruby typically provides information about the gem, such as its name, origin, or properties. In some contexts, it may also convey a message or signify its value. If you have a specific context or image in mind, please provide more details for a more precise response.
