Ruby is the most valuable variety of the corundum mineral species, which also includes sapphire. Rubies can command the highest per-carat price of any colored stone. This makes ruby one of the most important gems in the colored stone market. In its purest form, the mineral corundum is colorless. Trace elements that become part of the mineral’s crystal structure cause variations in its color. Chromium is the trace element that causes ruby’s red, which ranges from an orangy red to a purplish red. The strength of ruby’s red depends on how much chromium is present—the more chromium, the stronger the red color. Chromium can also cause fluorescence, which adds to the intensity of the red color. The most renowned rubies, like those from Myanmar, the Himalayas, and northern Vietnam, typically form in marble. They’re found in layers that are distributed irregularly within the surrounding marble. Marble forms as part of the metamorphic (rock-altering) process, when heat and pressure from mountain formation act on existing limestone deposits. ￼ Rubies found in marble deposits often have a vibrant red glow. Marble has low iron content, so the rubies that originate in marble (called “marble-hosted” by gemologists) lack iron. Because of this, many have an intense red color. In addition, rubies found in marble typically fluoresce red under ultraviolet light—even the ultraviolet light in sunlight. Fluorescence can make a ruby’s color even more intense and increase its value. In other locations, rubies can be found in basalt rocks. Rubies from these sources can have higher iron content, which can make the rubies darker and less intense in color. Higher iron content in the chemical makeup of a ruby can also mask the red fluorescence, eliminating that extra glow of red color seen in marble-hosted rubies.A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum(aluminium oxide). Other varieties of gem-quality corundum are called sapphires. Ruby is one of the traditional cardinal gems, together with amethyst, sapphire, emerald, and diamond. The word ruby comes from ruber, Latin for red. The color of a ruby is due to the element chromium.

The brightest and most valuable shade of red called blood-red or pigeon blood, commands a large premium over other rubies of similar quality. After color follows clarity: similar to diamonds, a clear stone will command a premium, but a ruby without any needle-like rutile inclusions may indicate that the stone has been treated. Ruby is the traditional birthstone for July and is usually pinker than garnet, although some rhodolite garnets have a similar pinkish hue to most rubies. The world's most valuable ruby is the Sunrise Ruby. During the past 25 years, the corundum market has been transformed from one of medium to high-priced gems to one that encompasses nearly all price ranges. This transformaDuring the past 25 years, the corundum market has been transformed from one of medium to high-priced gems to one that encompasses nearly all price ranges. This transformation was caused by the discovery of a number of large deposits and the development of treatment processes that enhanced the color and clarity of huge quantities of previously noncommercial sapphire and ruby. More recently, however, controversial treatments have undermined confidence and prices in some material, while political events and press scrutiny have affected the supply chain for rubies and sapphires from localities such as Myanmar and Madagascar #ruby#rubycutting#rubypolishing Hay gays im gemstone cutter from karachi Pakistan

A brief look at the route gemstones take from mines to market in Burma (Myanmar), starting in the Mountains of Mogok and finishing at the Thai border. Hosted by Charles Lawson of Lawson Gems. www.lawsongems.com

Mogok and other villages nearby have been famous since ancient times for its gemstones, especially ruby and sapphire, but semi-precious stones such as lapis lazuli, garnet, moonstone, peridot and chrysoberyl are also found. The gems are found in alluvial marble gravels by means of panning, tunneling and digging pits by hand. There is little mechanization of the mining. The gravels derive from the metamorphosed limestones (marbles) of the Mogok metamorphic belt. Gems are sold in markets in Mogok; however, foreigners require special permits to visit the town, and purchase/export of gems from Myanmar at non-government licensed dealers is illegal. 90% of the world's rubies come from Myanmar. The red stones from there are prized for their purity and hue. Thailand buys the majority of Myanmar's gems. The "Valley of Rubies", the mountainous Mogok area, 200 km (120 mi) north of Mandalay, is noted as the original source of ruby including the world's finest "pigeon's blood" rubies as well as the most world's most beautiful sapphires in "royal" blue.

Here we have a Natural unheated Ruby(origin is probably from Llakaka based on its inclusions-but I am not an expert on origin). When we observe this Ruby we find that the inclusions are undisturbed. We do find rutile also known as "silk", which is a natural inclusion commonly found in corundums(ruby and sapphire) and we find that there are nice euhedral shaped rutile inclusions. When we observed this ruby host, we find that the Rutile is undissolved and in a needle format that is intact and undisturbed. Because rutile has a lower melting point than the ruby, it would dissolve and be broken or be completely obliterated during the heating process. But because the rutile is so fine in the cloud I shoed in the video, along with the brownish red euhedral shaped rutile crystals that are undisturbed, we know that this is enough proof and evidence that this material is unheated.

www.TheNaturalSapphireCompany.com Rubies have been treasured for millennia for their incredible deep red color. Rubies and sapphires are two varieties of the same mineral species, corundum. The sapphire variety encompasses all sapphire colors including blue, yellow, green, purple, pink and a multitude of colors in between. The ruby variety only encompasses red corundum. The dividing line between what constitutes a ruby or a pink sapphire is a thin one. If a corundum gemstone is highly saturated, it would be considered a ruby. But, if the saturation is not quite as strong, it could fall within the pink sapphire category. There's something magical about the radiating color of a ruby, and it's no wonder that rubies are the most expensive of all corundum colors. Both rubies and sapphires derive their colors from specific minerals within their chemical makeup. Corundum is an aluminum oxide, meaning aluminium and oxygen are the essential components to create a corundum crystal. Pure corundum is clear, and creates a white sapphire. When tiny amounts of other minerals called trace elements are also present, they produce different colors. Iron is responsible for the widest range of colors in corundum. Iron creates yellow sapphires and titanium and iron create blue sapphires. Trace amounts of vanadium or chromium create the red of a ruby. In addition to their vivid red hue, some chromium rich rubies have the ability to fluoresce under longwave UV radiation. This response can also be a clue to a ruby's origin, as chromium rich rubies often form in marble deposits in Burma, a historic source for high quality gemstones. If you're searching for a ruby, color is usually the most important factor to consider. More leeway is given for variations in cut and clarity because highly saturated rubies are so hard to come by.

Before running the round vibrating screen, first start it to see whether there is anything abnormal. Then check whether the rotating direction of the motor conforms to the operation requirement. Jaw plate is installed on the jaw bed and the side guard board is directly used to press the materials, so the jaw board must be stable and strong. The flywheel is used to save the energy of dynamic jaw to make the machine work uniformly. And what should be care of is the balance of the flywheel. We must keep its balance when we install it. Cement mill is key equipment during the process of producing cement in cement making plant, and is used to grind the crude material, clinker, coal powder, calcium lime and other mixing materials.
