Emerald Cut/Antique Cushion Size/Weight ChargAntique cushion weights are similar to those of emerald cut. Pictures not actual size. Alexandrite is denser than diamond, so it weighs more for the same physical size. Because carat is a measurement of weight, not size, it’s important to order colored stones based on physical size rather than carat weight.
