BZ Diamond Education
Understanding the 4 Cs of Diamonds
Understanding the quality of a diamond is crucial for making an informed purchase. At BZ Diamond, we are committed to providing our customers with the knowledge and insights needed to make the best possible choice. This commitment to education is rooted in our belief that an informed customer is a satisfied customer, one who will appreciate the true value and beauty of their diamond purchase. To this end, we emphasize the importance of the 4 Cs—Cut, Color, Clarity, and Carat Weight. These four characteristics are the fundamental criteria that determine the overall quality, appearance, and value of a diamond.
It means how well the diamond has been shaped and faceted, which affects its brilliance and sparkle by determining how effectively it reflects and refracts light.
It refers to the presence of any tint or hue in the stone, with the most valuable diamonds being completely colorless, allowing more light to pass through and enhancing their brilliance.
In diamonds, "carat" refers to the unit of weight used to measure a diamond, with one carat equal to 200 milligrams, affecting the size and, consequently, the value of the diamond.
In diamonds, "clarity" refers to the presence and visibility of internal or external flaws, with higher clarity indicating fewer and less noticeable imperfections, increasing the diamond's overall value.
