Visually, there are no significant differences between 0.90-carat diamonds and 1.00-carat diamonds. In fact, to the naked eye, they are typically indiscernible. In general, if you opt for a 0.90-carat diamond you’re likely to pay 10-15% less than if you opt for a 1.00-carat diamond with similar quality specifications, i.e., cut, color, and clarity. So, if you want to get the best value, then 0.90-carat diamonds are ideal.
