Blue Sapphire Wedding Ring
The term "royal Blue" first appeared between 1810-1820. The name "royal blue" comes from British royalty. This shade of royal blue was created by a British tailor for a competition in order to create a dress to be worn by Queen Charlotte at the beginning of the 19th century.
The royal blue that we associate with it has changed. Prior to the 1950s, the original royal blue was considered much deeper than the official one approved in the 1980s by the World Wide Web Consortium, which associated the now lighter blue, along with its RGB code, with the name "Royal blue".
The original royal-blue colour of the United Kingdom's flag is closest to the royal blue sapphire used today.
Royal Blue describes sapphires that have the most vibrant and deepest saturation. It was probably the British gem trader who first used this term to describe sapphire, when Ceylon was still part of British Empire.
The symbolism of royal blue includes tranquility, as blue is the colour of the sky and the ocean, both of which are known to promote feelings of peace. The colour blue represents importance, significance and confidence. Blue corporate suits and blue uniforms are all derived from here.
The most important factor that determines the value of sapphires is its color. Royal blue describes sapphires with a pure blue to very slightly violetish blue hue, with a vivid saturation, which can in rare cases range from intense to deep, the tones should be medium to medium dark. offers more information regarding colour classification.
Clarity can have a significant impact on a sapphire's value. Royal blues sapphires need to be flawless. The colour uniformity must be excellent or evenly distributed.
Cut plays a very important role in the colour of a sapphire. Royal blue sapphires need to have good to excellent proportions in order to maximize internal reflection. If the face up view is taken, there should be no significant windowing.
Classifying the colour of gemstones is a combination of science and art. The adjective "Royal" encompasses many different facts about sapphires. It isn't as easy as you might think to classify a transparent anisotropic crystal like a blue Sapphire. For the sapphires to be considered royal blue, they must meet certain criteria.
The sapphire's blue color is due to a major chromophore, iron and titanium in pairs. The iron replaces some aluminium atoms. The more pairs of titanium and iron, the darker the sapphire. In Blue Sapphire stone , the iron and titanium content is approximately between a pair of tens or pairs of atoms. Two other chromophores almost always play a role in blue sapphire: iron and chromium. Iron tends to turn the sapphire green and increase its tone. Chromium turns it violet.
Quantifying chromophores is an excellent way to compare colours without having other factors influence the results, such as the reflections or the path of the light through the sapphire. Combining the chromophores present in a sapphire with its overall proportions allows us to analyze and compare the main colour factors.
Treatment of Royal blue sapphire is acceptable only for no treatment or traditional heating. Therefore, any other treatment such as diffusion of foreign ions into the sapphire lattice, like beryllium or titanium, fracture sealing with resin, or lead, cobalt and/or silicate glass, will not be granted a gemmological report and as such not qualified for Royal blue or any other colour grading.
