Throughout history, gemstones, more than a decorative element with extremely expensive jewels, have been seen as a symbol of power and status, valued by human beings for a long time.
For example, British royalty have an ostentatious collection of tiaras in which the precious stones that stand out are diamonds, pearls, rubies, emeralds, aquamarines, etc. But how do you know when one jewel is more valuable than another? Simple: its beauty, its strangeness and the high demand for it must be evaluated, experts say.
Formerly the term "precious stone" was used only for the four most important gems: diamond, ruby, sapphire and emerald. The other gems were called "semi-precious", a term now in disuse. In modern gemology, the terms "gem" and "precious stone" are used as synonyms, detailed on the website of the Spanish Gemological Institute.

The sapphire, one of the most expensive gems in the world
Jewelry experts say that the cheapest would be those cut gems, which tend to be valued by the piece instead of by the carat, as it should be. This is because the work involved in producing them usually exceeds the cost of the material.
Ruby
According to Forbes de México magazine, this gem is aluminum oxide and a very hard mineral, it has the number 9 rating on the Mohs scale. In a matter of color, reference is made to its bright red; however, it has various shades ranging from orange-red to purplish-red.
Ruby is found on all continents; in fact, the most important ruby deposits are found in Afghanistan, Cambodia, China, India, Kenya, Madagascar, Mozambique, Sri Lanka, Tanzania, Thailand, and Vietnam. However, this stone is more abundant in Sri Lanka, where it has been mined since 480 BC.
A carat of a high-quality ruby is traded worldwide for about $15,000 per carat. The most valuable rubies are the so-called "pigeon's blood", from Asia and characteristic for their pure red color with a violet hue.
To exemplify, Cartier presents a necklace decorated with 18 rubellites of sugar loaf with a total of 53.82 carats. Or, on the other hand, the Burmese Ruby and Diamond Ring collection, from the same brand.
Emerald
At the end of this list is perhaps one of the most popular gemstones of all, due to its bright green or dark green color.
The emerald is mainly produced in Colombia, so it could be said that it is a Latin gemstone . However, their prices are still quite high. Its cost is defined according to whether the clean stones are extremely rare, with those of exceptional quality being sold at more than 8,000 dollars per carat in the world market, according to the Navas Joyeros portal.
