Additional Details: Diamond is a mineral composed of pure carbon and is the hardest natural substance in the world, which is extracted from mines and cut by skilled and expert individuals. This valuable mineral originating from the element carbon has high hardness, which has caused it to be used in industry and goldsmithing. The hardness of this substance is so high that it can only be scratched by a diamond like itself. Other features of diamond include its unique brilliance and ability to reflect light in rainbow colors. The reflection of light causes the diamond to shine, and this feature adds to its value as a precious stone. The fame of diamond mineral is due to its variety, durability, beauty, and excellent quality, and it is one of the most popular precious stones in the world.

Brilliant in French refers to a type of cut performed on a diamond stone. This type of cut is known as the "Swiss cut," which was used in the past for various types of stones. In the brilliant cut today, efforts are made to display the visual aspects of the diamond stone more than before and to adjust the angles and type of cut so that the light entering the diamond stone hits more plates of the stone and finally reaches our eyes. To achieve this, scientists at major institutes in America and Belgium always try to improve the type of diamond cut and present new standards for this work year by year. In principle, all diamond cuts, whether traditional or with the help of advanced devices, must be done observing these standards. The brilliant cut consists of three parts which cause the brilliance and beauty of this small stone to increase. These three parts include: the Crown, the Girdle, and the Pavilion, where the girdle is actually the separating plate between the two upper parts, i.e., the crown, and the lower part, i.e., the pavilion. Each of the upper and lower sections consists of different triangular, rhombus, or kite-shaped facets, which create a total of 58 facets. These facets are created on the diamond by precise laser cuts and are called "Facets" in gemology terminology. At the final and sharp point of the brilliant, a Facet is also created called the "Culet" and is to protect the final part of the brilliant cut diamond against impact and breakage. In some brilliant cuts, this facet is removed and this part is made completely sharp, which is called "Full Cut" for such cuts, in which case a brilliant with 57 facets is created.

The marquise cut of diamond stone, an elongated shape with two sharp and delicate ends, has been the favorite of diamond lovers for centuries and is their popular choice. The history of the marquise cut dates back to the eighteenth century. According to legend, King Louis XV of France (1710-1774) ordered the court jewelers to make a diamond that would match the smile of his chief mistress, Jeanne Antoinette Poisson, Marquise de Pompadour. The story may be legendary, but the name Marquise indicates that this delicate cut was associated with the aristocracy, as the term Marquise (feminine form of Marquis) refers to a hereditary rank midway between Duke and Earl. Although it first appeared as a cut for diamonds, it has also become popular for colored precious stones. For example, you will see marquises in ruby and sapphire, as well as in other colored stones such as tanzanite, spinel, tsavorite garnet, topaz, and alexandrite.

Sapphire is a precious gemstone and a variety of the mineral corundum, consisting of aluminum oxide (α-Al2O3) with trace amounts of elements such as iron, titanium, chromium, vanadium, or magnesium. The color of this stone is usually blue, but natural "fancy" sapphire also exists in yellow, purple, orange, and green colors. "Sapphire" exhibits two or more colors. Red corundum stones also occur but are called ruby, not sapphire. Pink corundum may be classified as either ruby or sapphire. Usually, natural sapphire is cut and polished as precious stones and used in jewelry.
