Why Choose a 3 Carat Lab Grown Diamond

Understanding the 4Cs of 3 Carat Lab Grown Diamonds
The beauty and value of a 3 carat diamond are determined by the 4Cs — cut, colour, clarity and carat weight. Excellent or Ideal cut diamonds maximise brilliance and fire, while higher colour grades such as D, E and F provide a whiter and more colourless appearance. Clarity reflects internal purity, with VS and VVS grades offering superior transparency and light performance. Selecting the right combination of these factors ensures maximum sparkle and refined brilliance.
