What should couples check before choosing an engagement ring stone?

Do not choose based only on photos or carat size. Look at the stone in different lighting, check the return policy, and confirm exactly what material you are buying. Moissanite and simulated stones can look beautiful, but they are different from natural or lab-grown diamonds.

When my sister got engaged, she initially wanted the biggest stone possible, but after trying rings on she chose a smaller, well-cut lab-grown diamond in a simple platinum setting. It suited her hand better and felt more practical for everyday wear. Read the product description carefully, because some retailers sell both lab-grown diamonds and simulated alternatives. Before buying, check agape diamonds reviews and compare several jewelers.
