The radiant cut was only created in the mid-70s by Henry Grossbard who was a master diamond cutter. It's a deep cut with an average of 70 facets and is a perfect square even with its rounded edges. The radiant cut has the brilliance of the round cut. The radiant cut was created to take the round brilliant and the emerald cut to show off both of their best qualities. Pros of a Radiant Cut Diamond Engagement Ring Intensity of Brilliance Every woman wants an engagement ring that will sparkle with enough fire to blind all other women in the area. The radiant cut is known for its brilliance and ability to really outshine the other types of diamond cuts. This is due to the deep cut and many facets of the diamond. While not every woman wants to blind everyone in the area with her ring, she does want to get compliments on the fire and intensity of the shine. Won't Catch on Clothing The edges of the diamond do not stick out like a traditional square cut. The edged are trimmed, so the prongs won't catch on clothing. This means that the diamond ring can be worn for a variety of tasks that would normally require you to remove the ring. You can also do your hair without worrying that the ring will catch strands of hair on the edges. Rounded Corners Reduce Breakage The truncated corners will also reduce the risk of the diamond breaking along the edges. While it could take a huge amount of force to break the diamond, there's no chance of that with the curved, rounded edges. The…

The D-glucose serves to reduce the silver from Ag1- to Ag1+. The sodium citrate first reduces Ag1+ to Ag, and then functions to bind with the particle surface of silver nitrate particles to allow them to interact. Finally, silver nitrate can aggregate. The silver nitrate combined with D-glucose, sodium citrate, and heat forms an aggregate. The citrate binds with the particle coating and dispels the repulsion between silver nitrate nanoparticles. The nanoparticles then form an aggregate-- a loose…

Social and Environmental Impacts of the Gold Commodity Chain Gold’s unique qualities make it one of the most sought-after commodities in the world. Even in antiquity, gold was praised for its luster, shine, and beauty and was cast into jewelry and was widely regarded as a luxury item. Its inherent scarcity gave gold value and it became a symbol of status and wealth because those who could afford to frivolously spend on jewelry were well-off. In some societies, it even became a currency, shaped…

Gold is widely used in modern day medicine to treat disorders. This is because gold is very resistant to bacteria. Bacteria are microscopic single-celled organisms. Bacteria are prokaryotes, meaning the entire organism consists of a single cell with a simple internal structure. The DNA of a prokaryote is neatly packed in the nucleus. The bacterial DNA floats freely in a twisted thread-like mass called the nucleoid. Gold is unaffected by almost everything. The only materials that can affect gold…

One of the earliest metals to be discovered, lead has a long history with mankind. It was first discovered around 7000 BC as a byproduct of silver smelting. Lead is metal known for its resistance against corrosion, malleability, and low melting point. Mined all across the world, lead was one of the most important metals in ancient times. Although lead was toxic, it was used widely, particularly in the Roman Empire. Through its uses and toxicity, lead affected the classical era in a drastic way. …

A polymer is a large molecule which is formed by repeated linkage of small molecule called monomers. Conducting polymer have been the subjects for many decades as possible synthetic metals. Many of these polymer, especially those with a conjugated pi-bond system ,often yield higher conductivity once having undergone the doping process. Polymers are typically insulators due to their very high resistivity .Insulators have tightly bound electrons so that nearly no electron flow occurs ,and they…

of silver are mined yearly? That is equal to more than 46,011,428 pounds of silver! The word silver comes from the Anglo-Saxon word seolfor. Along with the words purple and orange, there is no word in the English language that rhyme with the word silver. Silver is a metallic metal with the atomic number of forty-seven, out of the 118 elements on the periodic table, silver is the best reflector of light. Prior to 1965, all U.S. coins were about 90% silver. History Mining In about 3,000…

Tin was really popular during the civil war. This tin filling was used when the patient couldn’t afford the gold filling. The tin filling also could sometimes be placed in places where the gold fillings could not fit. Platinum was used occasionally during the 19th century. Platinum was only occasionally used because it’s too hard to be formed in to a foil. [2] Silver was a popular filling also during the 19th century but like platinum was hard to be used. Both silver and platinum are less…
