Lab grown diamonds are chemically and physically similar to their natural diamond counterparts. These diamonds may be created in laboratories. These days, it is possible to get lab grown diamonds that are every bit as stunning as their natural counterparts and are available in virtually the same range of sizes and colors.
A brief history-
Lab grown diamonds have been made for use in industry since the 1950s. These diamonds have found uses in a variety of fields, including telecommunications, laser optics, abrasives, and more. On the other hand, in 1970, scientists working for GE generated the first lab grown diamonds that were suitable for use in jewelry.
It wasn’t until the middle of the 1980s that manufacturers started producing synthetic crystals of gem-quality in big quantities. These diamonds were often rather little and had a yellowish or brownish appearance to them. However, the quality of these diamonds has progressively grown over the decades since then, and the lab grown diamonds available today may even be able to compete with real diamonds of excellent grade in terms of their appearance.
How are lab grown diamonds made?
In modern laboratories, it is possible to create diamonds in a matter of days or weeks, whereas natural diamonds originated millions to billions of years ago beneath the surface of the earth. The two most common techniques are known as high-pressure high-temperature and chemical vapour deposition
Using the HPHT method, laboratories are able to manufacture diamonds by using machinery that, in effect, recreates the high pressure and high temperature conditions that prevail deep under the earth and are responsible for the formation of genuine diamonds. The final output consists of diamond crystals that have faces that are cuboid and octahedral and have a flat base. As a result of advancements in technology, the coloration of HPHT lab grown diamonds has shifted. The orange-yellow, yellow, and yellow-orange synthetic stones that were formerly submitted to GIA labs have now been changed to colorless, virtually colorless, or blue versions of themselves. Post-growth treatments like as high-pressure high-temperature (HPHT) may be used to color diamonds of any kind, including natural and man-made diamonds, different colors such as pink, blue, and others.
Chemical vapour deposition-
A vacuum chamber is used to crystallise carbon from carbon-containing gas onto diamond seed plates as part of this cutting-edge process. The resulting crystals are typically tabular in shape and contain graphite along the edges of their surfaces. These crystals have a tint that is either brownish or yellowish in appearance; however, further HPHT treatment may cause them to nearly completely lose their color. The majority of CVD diamonds that are polished and marketed as jewelry have a clarity grade that ranges from Very Very Slightly Included (VVS2) to Slightly Included (VS1), which is just a little improvement over the natural diamonds that they are designed to mimic. The overwhelming majority of natural diamonds that have a colour that falls somewhere between D and N are assigned clarity grades that fall anywhere between VS2 and SI1.
Do lab grown diamonds look like natural diamonds?
Diamonds produced in a laboratory are astonishingly similar to real diamonds in terms of their appearance and the way they behave in the body. They are available in a comparable range of quality levels and color choices, and their durability is not compromised in any way. In the same way as, actual diamonds are graded by their fire, brilliance, and scintillation, the shape of the raw material and the skill of the cutter decide whether or not the end product will have these qualities. It is not impossible for pink and blue diamonds created in a laboratory to have a shade that is more muted than their natural counterparts. It is common for lab-grown pink and blue diamonds to have a deeper saturation of color with less traces of secondary coloration, and in all other respects, they seem to be fairly comparable to natural diamonds.
Lab grown diamonds may be purchased for a fraction of the cost of genuine diamonds while yet maintaining the same brilliance and durability. These diamonds may be produced in a laboratory using HPHT or CVD procedures in a matter of days or weeks.
