A natural diamond is formed in the earth from carbon being subjected to extreme heat and pressure deep underneath the earth’s crust. When people mention natural diamond, it is referring to a mined diamond.

When people talk about natural diamonds, the 4Cs refer to a global standard created by GIA namely, cut, carat, clarity, and colour. These are the four primary characteristics used to grade a mined diamond. In ZCOVA, we go beyond the 4Cs standard to assure you of the brilliance of a diamond.

A Diamond’s cut is also often referred to as the diamond’s shape but we’re not talking about that here. The diamond’s cut we’re referring to now is the diamond’s proportion, angle and how well the facets reflect light. Among the 4Cs, the cut of a mined diamond is considered the most important aspect because an excellent cut diamond will reflect light better hence getting better brilliance.

Lab diamonds and mined diamonds are the same in every way. The only difference between the two is that lab diamonds are grown in a lab. Other than that, they have all the same chemical, physical and aesthetic properties needed to sparkle.

Yes! Using a microscope you can find at most diamond stores, you can locate the laser inscription on the diamond’s girdle. At ZCOVA, our mined diamonds are certified by GIA while our lab grown diamond are certified by IGI.
