Sapphires are a well-known gemstone that is often used in sought-after and unique jewelry due to their beauty and symbolic meaning. The blue color is the most common and characteristic feature of sapphires. The gemstone primarily consists of the mineral corundum, which is the second hardest mineral in the world, second only to diamonds.
Corundum is colorless in its natural form. It is the presence of iron and titanium that gives the sapphire its beautiful blue color. In fact, sapphire can occur in any color except red. When the sapphire has a red color, it is called a ruby. The most common non-blue sapphires are found in shades such as yellow, green and pink.
Among sapphires, the blue variety is the most sought after. Within this color group, the lighter grain blue sapphire is particularly sought after, while the darker shades are considered less valuable. Sapphires can either occur naturally or be produced synthetically through laboratory processes.
Naturally occurring sapphires can be found anywhere in the world, but geographic location can have a significant impact on the blue hue. For example, Kashmir sapphires, which come from the Kashmir region of India, have an intense blue color that is considered to be of extraordinary quality and rarity. Sapphires from other places such as Burma, Sri Lanka and Australia also have their unique characteristics and hues.
Whether they represent truth, wisdom or a symbolic connection to the heavens, sapphires have an irresistible beauty and profound meaning that continues to fascinate and attract admirers around the world.
The ruby is known for its deep red color and is considered one of the most valuable gemstones. Like the sapphire, the ruby consists primarily of the mineral corundum. The red color in the ruby is due to the presence of chromium and can vary from an intense orange-red to a deep purple-red. The name "ruby" comes from the Latin word "rubrum" meaning red.
Naturally occurring rubies are extremely rare and therefore have a high value. They are only found in a few selected regions around the world. However, rubies can also be produced synthetically in laboratories, although the natural rubies are still considered more valuable and sought after.
Among the natural rubies, the red-violet color known as "Pigeon Blood" is considered the most valuable. This color is deep and intense, giving the ruby a unique beauty and aesthetic appeal.
Rubies have long been associated with love, passion and strength. They are also considered symbols of good luck and protection against negative energy. The ruby has historical significance and has adorned royal jewelry and crowns in many cultures.
Whether natural or synthetic, rubies have a magnetic appeal due to their intense red color and symbolic meaning.
Emerald comes from the Greek word smaragdos and means green stone. An emerald is a green gemstone that is related to the mineral beryl. Like corundum, beryl is basically transparent and transparent. It is only through the presence of various impurities that the many colorful shades arise.
In emeralds, the greenish color is due to chromium and sometimes also vanadium. Sometimes iron will also be present in beryl, giving it a bluish hue.
Emeralds have always been highly sought after gemstones, which is also reflected in the price. An emerald can be more expensive and valuable than diamonds if it is of high quality. An emerald from Colombia is considered to be the most sought after, but also the most expensive of its kind.
The most valuable emeralds are in the blue-green to green color spectrum and have a medium dark shade. Since emeralds crystallize hexagonally, they will typically take the form of hexagonal prisms, which is the typical appearance of an emerald. It is characterized by its elongated, rectangular shape. This type of gemstone is also characterized by having visible inclusions. Emeralds are easy to recognize due to their intense green colors and shape.
Amethyst is a beautiful purple gemstone and belongs to the quartz family. The color can vary from deep violet to pale lavender and it can even have reddish undertones.

Amethysts come from different places around the world, and the gemstone's country of origin plays a role in color variation. Amethysts come primarily from Brazil, Uruguay, the Ural Mountains and Sri Lanka. The expression and appearance of amethysts can vary, which also affects the value. Amethysts with a deep violet color without inclusions are considered the most valuable.
Amethysts are not only beautiful gemstones, but also have a symbolic meaning. They are said to represent clarity, spiritual awareness and protection from negative energies. Amethyst is also considered a calming stone that can help relieve stress and promote inner peace and balance.
Whether it is the deep violet amethyst or the delicate lavender hue, the amethyst is a gemstone that continues to fascinate with its color and beauty. The historical significance and its presence in different cultures make the amethyst a popular and loved gemstone all over the world.
Garnets are a type of gemstone known for its deep red color. The name "garnet" comes from the Latin word "granatum" meaning "grainy" or "seed-like". Garnets come in a wide variety of colors, including red, orange, yellow, brown, green, and even colorless. However, the red variety, known as almandine garnet, is the best known and sought after.
