It is not necessary to have great knowledge to know that precious stones are some of the most exquisite and beautiful natural treasures on earth. Throughout history, they have been appreciated by people all over the world. Commonly used in decorative ornaments, such as jewelry, precious stones have a distinct beauty that highlights them, making some rarer than others. Thus, depending on their rarity, these can be assumed as valuable investments for the future.

Come and discover with us the precious stones you will want to have in your possession and, who knows, in your jewelry pieces.

Diamond

We started our list with probably the best-known gemstone: the diamond, and for good reason! It is the hardest and most resistant mineral found in nature and, consequently, one of the most valued and appreciated since the dawn of humanity. Diamonds have a special luster designed by their crystallized pure carbon property. Contrary to what many think, diamonds are not only colorless and can be found in a multitude of colors, involving brown, yellow, grey, red, pink, blue or green.

But after all, what makes the diamond so valued? For this, we must take into account the 4 c's:

• Its color;
• Its cutting and stoning, which should prioritize its brightness;
• Clarity or, if we wish, the purity of the stone;
• Carat: The more, the more valuable the stone

Nevertheless, did you know that most of the diamonds extracted today are not used in jewelry? That's that... its use is highly used for industrial purposes of cutting, drilling and polishing.

Ruby

Following the hardness order of the stone, ruby is the second toughest natural gem stone in the world. Marked by its characteristic red and pink color, this stone is strongly associated with mysticism and love, being widely used in jewelry and engagement pieces. For much of humanity, ruby was classified as the most valuable stone because of its extravagant colors.

Ruby gems are valued according to diamond-like characteristics, encompassing their size, color, clarity and cut.

Curiosity: Did you know that all natural rubies contain imperfections? If this is not observed, it will most likely be in possession of an artificial ruby.

Emerald

Emeralds are one of the most popular gems in the world, known for their exotic shades of green. The price per carat of emeralds projects them among the most valuable stones in the world, losing some of that value often due to the inclusions that occur in all emeralds.

Most of the emeralds available on the market have small imperfections. Thus, in the rare opportunity of a natural emerald without defects being put up for sale, it can yield mind-blowing numbers, as was the case with an emerald sold for 5.5 million dollars.

Sapphire

Known for its deep blue tone, sapphire is one of the most desired and coveted gems in the world. Although it can be found in nature in various shades, sapphires are appreciated for their durability and often appear associated with the nobility and kings of the past, as well as romance and engagement items, much because of their use by Princess Diana Spencer. Due to their strength, some luxury watches brands use sapphire-coated glass for their protection.
