Rubies can improve society by driving economic growth through mining and trading activities, creating job opportunities for miners, traders, and craftsmen. They also contribute to cultural heritage and tourism. Additionally, the sales of rubies can generate revenue for governments, which can be invested in public services and infrastructure, benefiting society as a whole.
Rubies have historically been mined using traditional methods such as panning in rivers, open-pit mining, and underground mining. In some locations, rubies are also recovered by washing and sorting through alluvial deposits. Modern techniques incorporate machinery and technology to extract rubies more efficiently while minimizing environmental impact.
Rubies, although good thermal conductors, are not naturally conductive of electricity, due to how electrons are tied up in the crystal lattice, not free to move as they are in metals. However sometimes impurities can enable them to conduct; also, it is possible to excite ruby with radiation and induce a limited electrical conductivity.
Gemology is a vast field where the primary focus is to identify stones correctly. One cannot guarantee whether the stone is real or fake unless one knows properties of gemstone.
* Separation of gemstone from man-made glass: Glass exhibits a round to elongated gas bubbles. Gas bubbles are spherical cavity. Sometimes it gets confuse with round crystal fingerprints in natural gemstone.
* Separation of gemstone from plastic: Using hot needle point to test the stone will give a peculiar odour and may melt where the hot point is applied.

The value of any gem depends on its rarity, size, color and flawlessness - and on the market at the moment. Pigeon's blood rubies are pretty rare, so it would be worth more than an ordinary one, but there's no way to value something like that over the internet. You'd need to take it to a reputable jeweler.
That would depend on the size, color quality, and clarity of the ruby.
Ruby's chemical make up is AL2O3:CR, that means that every molecule in it has 2 atoms of aluminum, 3 atoms of oxygen connected to an atom of chromium. In the 1800's chemists figured out that by combining aluminum oxide with chromium at high heat they would get synthetic ruby.
The process has been modified through the years but, chemically speaking, synthetic ruby is the same as natural ruby. From a retail point of view they are worlds apart and man-made stones must be marked as such and cannot be sold as ruby.
Rubies tend to be valuable because they're rarer gems and part of the four precious stones. They're often used to make beautiful jewelry, and genuine ruby can be difficult to find.
No. Rubies are specifically a red variant of corundum. Any gem-quality corundum that is no red is considered a sapphire. Green sapphires do exist.
