    Lab grown diamonds (also known as lab created diamonds, man-made diamonds, engineered diamonds, and cultured diamonds) are grown in highly controlled laboratory environments using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth\u2019s crust. These lab-created diamonds consist of actual carbon atoms arranged in the characteristic diamond crystal structure. Since they are made of the same material as natural diamonds, they exhibit the same optical and chemical properties.<\/span><\/p>

    Think of it this way: laboratory-grown diamonds are like ice from your refrigerator, while natural diamonds are like ice from a glacier. They are both ice, although their formation stories and the age of each are very different.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Even though several claims were made about lab diamond manufacturing during the period of 1879 to 1928, none of them are confirmed. Resources say, General Electric (GE) created the first batch of lab created diamonds in 1954. Forward to the 1970s, that is when gem-quality lab stones have been available. Commercially, however, in the 1980s is when high-quality man made diamonds became accessible. In the last decade, the processes around creating lab grown diamonds have improved monumentally, making it so these diamonds are possible for use in jewelry and diamond engagement rings.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    There are two primary methods<\/span> of producing lab diamonds:<\/span><\/p>

    1.High Pressure High Temperature (HPHT):<\/strong> This method mimics the conditions under which natural diamonds are formed inside the earth. To produce the lab diamond, a large machine is fed a certain amount of carbon material that it then crushes under pressures of more than 870,000 lbs. per square inch at extreme temperatures ranging from 1300 \u2013 1600 degrees Celsius.<\/span><\/p>

    2.Chemical Vapor Deposition (CVD):<\/strong> CVD is when a seed diamond is placed in a small, vacuum chamber filled with heated hydrogen and carbon-containing gases. At a certain temperature, the gas molecules are broken down and layers of crystallized carbon begin to form around the seed, growing a more substantial diamond. Some lab diamonds created through CVD may also undergo pressure and heat treatment after they are grown.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    The answer is ‘Yes!’<\/span><\/span><\/strong><\/span><\/p>

    Lab grown diamonds are <\/span><\/span>100% real diamonds<\/span><\/span>, with the same properties that natural diamonds have. Lab diamonds have no physical differences from natural diamonds, and it is impossible to tell them apart without specialist laboratory equipment.<\/span><\/span>\u00a0<\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Both are diamonds, of course!<\/span><\/span><\/strong><\/p>

    The first is a natural diamond created by forces deep within the young Earth. The second is from a laboratory and <\/span>possesses<\/span> essentially the<\/span> same<\/span>\u00a0chemical, physical and optical properties as its natural counterpart.<\/span><\/p>

    The only noticeable difference between them is their origin<\/strong>: one was formed deep within the Earth, the other was grown in a lab.<\/span><\/span><\/p>
