WHAT ARE RUBIES AND WHAT ARE THEY MADE OF???
A ruby is a type of the mineral corundum that ranges in color from pinkish red to blood-red (aluminium oxide). One of the most well-liked traditional jewelry jewels is ruby, which is also quite strong. Sapphires are the name for many corundum variations that are gem-quality. Ruby, along with amethyst, sapphire, emerald, and diamond, is one of the classic cardinal stones. Ruby derives from the Latin word ruber, which means red. The element chromium is responsible for a ruby's hue.
A ruby's quality is defined by its color, cut, and clarity, which also have an impact on its value together with the stone's carat weight. Blood-red, sometimes known as pigeon blood, is the most vivid and expensive hue of red and fetches a high premium above other rubies of comparable grade. Following color is clarity; comparable to diamonds, a clear stone will be more expensive, but the absence of needle-like rutile inclusions in a ruby may be a sign that it has been treated. The traditional July birthstone is the ruby, which tends to be pinker than garnet, while some rhodolite garnets have a pinkish tint that is similar to most rubies. The Sunrise Ruby is the most expensive ruby in the world that will be auctioned off.
According to the Mohs scale of mineral hardness, rubies have a hardness of 9.0. Only diamond and moissanite are tougher natural gems; diamond has a Mohs hardness of 10.0, and moissanite has a hardness that is midway between corundum (ruby) and diamond. In pure corundum, this leaves all of the aluminum ions with a very stable configuration of no unpaired electrons or unfilled energy levels, and the crystal is perfectly colorless and transparent except for flaws. Sapphire, ruby, and pure corundum are all forms of "alumina," the most stable form of Al2O3, in which 3 electrons leave each aluminum ion to join the regular octahedral group of six nearby O2 ions.
ARE RUBIES THEY VALUBLE???
Color: When evaluating colored gemstones, color is by far the most crucial element. Three elements make up color: hue, saturation, and tone. Hue is the same as how we typically refer to color. The pure spectrum colors of red, orange, yellow, green, blue, and violet can be found in transparent gemstones. Natural colors are rarely pure, thus when discussing a gemstone's color, we refer to its primary, secondary, and occasionally tertiary colors. Red is the definition of ruby. Sapphire is the name given to the other colors of the corundum gem species. Numerous secondary colors, such as orange, purple, violet, and pink, can be seen in ruby.
Clarity: Due to the abundance of inclusions in rubies, the size, quantity, location, and visibility of the inclusions are used to assess the clarity of the gemstone. Due to the fact that inclusions are least noticeable to the unaided eye, rubies with the highest clarity ratings are referred to as "eye-clean." Silk-like inclusions, which are slender and intersect, can also be seen in rubies. Since extreme heat will damage a ruby's silk, the existence of silk can also reveal whether a ruby has previously undergone heat treatment, enhancing the appearance of the gem.
