Most diamonds in engagement rings weigh between 1.00 and 1.09 carats, making a one-carat natural solitaire the most popular choice. There is no fixed rule about the size of the diamond in an engagement ring: you simply select the ring that best suits your loved one, from fine and elegant to striking and imposing. A halo engagement ring, where a central diamond is encircled by smaller stones, makes the centre stone appear larger, while clustered smaller diamonds cost less for the same total carat weight. When the ring must truly stand out, the diamond can weigh up to 5 carats. Every BAUNAT diamond is natural and certified by GIA, HRD or IGI.
