4 C’s

Lab-grown diamonds can come in a wide range of carat weights, just like natural diamonds. The carat weight of a lab-grown diamond is determined by its size, with one carat equal to 200 milligrams. Lab-grown diamonds can be found in sizes as small as a fraction of a carat to several carats or more.

Pros and cons of Laboratory-Grown Diamonds with a Radiant Cut:

Pros

Laboratory-grown diamonds with a radiant cut possess several advantages that make them an appealing choice for jewellery. One notable benefit is their brilliance and sparkle. Radiant-cut diamonds, whether lab-grown or natural, are renowned for their ability to reflect light and create a dazzling display of brilliance. The radiant cut combines the elegance of an emerald cut with the sparkle of a round brilliant cut, resulting in a striking and eye-catching appearance.

Yes, lab-grown diamonds can be of excellent quality. The quality of a lab-grown diamond is determined by the same factors that apply to natural diamonds, often referred to as the "Four Cs":

Lab-grown diamonds, also known as synthetic diamonds or man-made diamonds, have the same hardness as natural diamonds because they share the same chemical composition. Both lab-grown and natural diamonds are composed of pure carbon atoms arranged in a crystal lattice structure, which gives them their exceptional hardness.

Lab-grown diamonds are graded using the same criteria as natural diamonds. The most common grading system for both types of diamonds is the "Four Cs" – Cut, Colour, Clarity, and Carat Weight. These factors help determine the quality and value of the lab-grown diamond:

Lab-grown diamonds can indeed be found in the D colour grade, which is the highest colour grade on the diamond colour scale. A D colour lab-grown diamond is considered colourless, meaning it shows no traces of colour to the naked eye. It is exceptionally rare to find natural diamonds with a D colour grade, but lab-grown diamonds have the advantage of being produced with precise control over their colour.

A diamond tester is a device used to determine whether a gemstone is a real diamond or a simulant (such as cubic zirconia or moissanite). It measures the thermal conductivity of the gemstone, which is a property that differs between diamonds and most simulants.

Lab-grown diamonds can be produced using two primary methods: Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT). Each method has its own advantages and disadvantages, making them suitable for different applications and preferences.

The 4Cs of diamonds are a system of grading diamonds based on four characteristics: cut, colour, clarity, and carat or carat weight. These four characteristics have existed since diamonds were first discovered and as a benchmark for quality relative to which a pricing structure would later evolve, upon which to compare a diamond's value and worth, especially relative to one another.
