The pearl and ruby ring is named for its red color, from the Latin "Rubeus", the element of fire par excellence. It symbolizes the courage, charity and divine love. The red of a pearl and ruby ring ??can have many shades, the most sought after being the so-called "pigeon blood" pure red with a hint of blue. Much rarer than diamonds, emeralds and sapphires, rubies are the stones most sought after by collectors. Some people have conferred powers. Hindus have always considered the most important stone by naming the Sanskrit Ratna Raj, the "queen of gems". The princes in turn carried it because of its prophetic power: he announced the bad omens when its brightness suddenly went from red to black. With powers higher, it is found on the crowns of Europe, in memory of suffering and blood of Christ. The stone symbolized the sacrifice of the sovereign who began serving his country and its people. Among the most costly gems, large pearl and ruby ring ??gems are rarer than diamonds of equal size. The largest gem quality rubies found in Burma weighed 400 carats and was divided into three. The ruby ??mounted on the crown of St. Wenceslas known (King of Bohemia in the tenth century) is probably the largest known gem-quality ruby, weighing 250 carats. The high specific weight of the pearl and ruby ring ??allows it to concentrate by washing the gravel and sand river, and is then sorted by hand. Operating procedures have not changed for centuries, although some wells have developed advanced techniques (including Mogok, Burma). The largest holdings are in Burma (Mogok and Mong Shu), Thailand ("the famous pearl and ruby ring of Siam"), Madagascar and Tanzania. Other deposits exist, but not very significant: in Afghanistan, Australia, Brazil, Cambodia, USA . . In its raw state, ruby, often rolled, is greasy. Once cut, its brightness is close to that of diamond. Although not as hard as diamond (hardness of 9 on a scale of 10), pearl and ruby ring ??is not as fragile as it has no cleavage plane. Today, most rubies are cut in the country where they come from, although some stones are recut later in Europe. Sizes in degrees (rectangles and squares) and bright (oval, round and pear . . ) are particularly suitable for transparent gems. Stones earn less transparent, however, to be cut en cabochon (size characterized by flat surfaces and completely devoid of facets) or to be carved into an object of display. As for the inclusions, they are very common and can affect the quality of the stone. In any case, they guarantee the authenticity of natural pearl and ruby ring ??compared to synthetic rubies.
