Posted by Lab diamonds are created by man and are not found in nature like natural diamonds are. However, with the growing popularity of lab-created diamonds, people have started wondering how they ensure that their product will be as close to natural diamonds as possible, and whether or not there are quality guarantees on Lab-created diamonds just like there are on natural diamonds. This article will discuss some of how Lab diamonds are made to ensure that their customers get the best value for their money.
Introduction
Lab-created diamonds are grown in a laboratory and have the same chemical, physical and optical properties as a mined diamond. Contrary to popular belief, lab-created diamonds are not synthetic. To help consumers understand that a lab-created diamond is an authentic diamond, GIA developed the GIA Diamond Grading SystemTM (GDS) for lab-created diamonds and adopted the term laboratory grown to describe them. The GDS helps consumers identify these stones as they shop for engagement rings or other jewelry items. Lab diamonds from different manufacturers may be graded differently according to specific standards unique to each manufacturer. For example, some companies grade the colour of a lab diamond on its relative ability to hide imperfections when it’s viewed under different light sources like candlelight or sunlight.
Lab diamonds also provide transparency through laser inscription. In this process, a machine records all of the data points needed for grading into small grooves on the surface of the stone and then reads those data points with lasers during grading by professionals at a gemological institute

The Four C’s Of Quality
Lab diamonds are created in a lab instead of mined from the earth. The four C’s of diamond quality are cut colour, clarity and carat weight. The cut is based on the angles and proportions of the stone and how well it reflects light. Color is judged by its degree of whiteness or yellow tint. Clarity can be graded as flawless, very slight inclusions or visible inclusions. Carat weight depends on how heavy an individual diamond is. When it comes to grading diamonds, there are guidelines set by the Gemological Institute of America (GIA). GIA uses 10 criteria for grading, which include: luster/lusterless; polish/good polish; symmetry/symmetrical; the number of characteristics present; relative proportion to one another; size in proportion to other stones in setting; fluorescence (will emit a different colour when exposed to ultraviolet light); adamantine (a reflective life that causes the jewel to sparkle)
The Diamond Grading Process
Lab-created diamonds are graded just like mined stones. The Gemological Institute of America’s (GIA) grading is the most popular and widely recognized grading scale. There are four grades: Flawless, Internally Flawless, Very Slightly Included (VSI), and Included. A stone’s grade is determined by a team of GIA-trained graders who have access to a variety of diamond clarity-enhancing equipment such as microscopes, polishers, and loupes. GIA graders consider both the exterior and interior aspects of each diamond when determining its grade.
The Benefits Of Buying A Lab-Grown Diamond
Lab Diamonds are treated with the same care and consideration as any other diamond. The only difference is that they are created in a laboratory, not in nature. Customers need to understand this distinction so they can make an informed decision about whether or not to buy a lab-created diamond. CVD diamonds are made of the same materials and by the same processes as natural diamonds. They’re just created by humans instead of Mother Nature, which is why they’re called Lab diamonds. As long as you find a reliable manufacturer, your investment will be safe and sound because you’ll know what you’re buying is exactly what it says it is – no surprises.
Conclusion
Lab diamonds are created in a lab and are not mined from the earth. They are made of the same material as mined diamonds but don’t have any imperfections that can alter how they look lab created diamonds. To avoid any confusion about the diamond’s authenticity, all lab diamonds come with a laser inscription on the girdle identifying its laboratory of origin. The inscription is visible only under magnification and will be located on one side of the diamond when looking at it face-up or on either side when looking at it from above.
