Only diamonds are harder than rubies. Rubies are rare. When not red, it’s a sapphire.
Rubies are striking gemstones. Like diamonds, they are cut in a variety of shapes and facets. They can also not be cut and instead polished smooth, which is a cabochon ruby.
Also like diamonds, you can buy synthetic rubies. However, if you want the real deal, you’ll have to pay. The most expensive ruby ever sold is called the Sunrise ruby, which is a 25.59-carat ruby ring that sold for $30,335,698. That works out to $1,185,451 per carat.
Of course, you don’t need $30 million for a ruby gemstone. You can get them for a lot less, but do expect to pay into the thousands of dollars.
How rubies are formed?
Like other gemstones, they form in the earth. In the case of rubies, they are formed from corundum which is made from densely packed oxygen and aluminum atoms. The red color materializes when some of the aluminum atoms are replaced by other minerals such as chromium [Source: Four Mine].

16. Types of Synthetic Rubies
Although these types of rubies make good gifts, they are not very popular nowadays. They usually have an imitation backing and a crown made out of a natural corundum, either white or green in color, and if you look at them hard enough, you can even see the glue that the stone was made with.
Unlike other synthetic rubies, this one has a very realistic look. The process used to make the rubies is a high-quality process that includes the right amount of pressure and the right temperature, and even though they can develop fractures during the production stage, this usually gives the gem a more natural look in the end.
