Different marbles are made from different minerals, and each mineral has a different color and hardness. For example, rubies from Khanna gems are red colored gemstones made from corundum; they are hard, shiny and transparent. The word ruby comes from the Latin word ruber, the Latin word for red.

Ruby gemstones are the red variety of natural corundum, meaning they are composed of aluminum oxide with traces of iron. Although their color is best seen in shades like pink and burgundy, ruby can also be found in colors like purple and white.
1. Ruby Gemstone
Ruby is a hard stone; in fact, if you judge its hardness on a scale of 1 to 10, with 10 being the hardest, it would rank at a 9. This means you can scratch any other stone with a ruby. The Mohs scale, was invented by Friedrich Mohs in 1812 to measure the hardness of different minerals. It uses a scale from 1 to 10 based on how easily one mineral can scratch another mineral. A mineral is said to be harder if it can scratch a softer mineral under an applied load, on a scale of 1 to 10. If a ruby cannot scratch another mineral (on this scale), it is considered to be harder than the other stone.
2. Ruby History
Ruby is only found in Sri Lanka, Burma and Madagascar. There are over 60 different rubies in the world, but most of them come from Sri Lanka and Burma. Rubies & Khanna gem are also mined in the United States and Australia, but they are even rarer; only 0.5% of the rubies mined in the world come from these two countries.
The main mineral that makes up rubies is corundum, which is a crystal made of aluminum oxide. Cobalt, iron and oxygen all make up about 60% of corundum’s composition. It is believed that rubies get their color from traces of chromium and vanadium – two elements other than aluminum oxide. Iron and cobalt give rubies gem a pinkish-red color, while vanadium gives them a brownish-red color. You can easily buy it from Khanna gems

The color of rubies is determined by the amount of iron in them – the higher the amount of iron, the darker the red. The amount of iron in rubies & Khanna gems ranges from about 1% to about 3%, but most rubies contain less than 1%. Due to this, most rubies are very dark red, which makes them difficult to distinguish from other stones. Most rubies also contain a small amount of chromium to make their color more constant.
The hardness of rubies is determined by the amount of aluminum they contain. The harder rubies and khanna gems contain less aluminum than softer ones, so they are harder to scratch than softer rubies. Now that the Mohs scale has been invented, it is possible to find out the hardness of a ruby by putting it on the scale and scratching another mineral with it on a scale from 1 to 10, with 10 being the hardest. Rubies gem are approximately 1.5 times as hard as the hardest mineral on the Mohs scale.
Ruby gem is found in several different colors and sizes, and most of them are found in Sri Lanka, Burma, Australia and the United States. The largest ruby gem and khanna gem ever discovered weighed more than 10 carats; it was found in Burma. The largest ruby ever mined came from Australia, and it weighed more than 30 carats – though we don’t know exactly how much as it was never sold at auction.
4. Cut and polished
Rubies have to be cut and polished in order to make them suitable for jewelry. Usually, high-quality rubies gems are sold by their weight. For example, a 12-carat ruby is more expensive than a 10-carat ruby, even though the 10-carat one might actually be larger.
The cost of a ruby gem is determined by its size and its color. Some rubies gem can be cut into gemstones as large as 50 carats or even more – but these are extremely rare and very valuable.
5. Value of Ruby Gems
Ruby gem and khanna gems is the second-hardest mineral on the Mohs scale – only diamond is harder.
However, unlike diamonds, rubies do not naturally occur in octahedral form. Instead, natural rubies gems have rounded corners and uneven textures. It takes a very skilled cutter to polish them into the beautiful gems you see today. Most rubies gems and khanna gems are mined in Sri Lanka and Burma, which are sought after for their large deposits of ruby.
Rubies gems have been highly valued throughout history, thanks to their beauty and durability. They were used as talismans, amulets and even medicine in ancient times; some people believed that it would prevent bleeding when worn on the body during surgery. The Greeks also believed that rubies gems could improve eyesight, and they thought it had the ability to detect poison, protect against demons and prevent death.
6. Ruby Latin words
The word ruby comes from the Latin word ruber, which means red. Rubies have been appreciated for thousands of years, and they have made their way into some major historical events. The Taj Mahal in India, for example, features a stone called “The Ruby of Babur,” which was given to his wife by the founder of the Mughal Empire in 1526.
The ancient Romans also loved rubies gems. They would often use them as coins in their day-to-day transactions, because they were relatively cheap and easy to carry. In fact, the word “ruble” comes from the word “rubrum” – which means ruby in Latin. In Ancient Rome, rubies were considered symbols of nobility and wealth; only rich people could afford to buy them for jewelry.
Rubies gems have also made appearances in some major artworks. The eye of the Hindu goddess Kali in the Hindu goddess Kali’s idol has been set with a ruby. Rubies gems can also be found on the Statue of Liberty in New York; they’ve been placed on her crown to represent America’s Four Freedoms: freedom of speech, freedom of worship, freedom from want and freedom from fear.
