Factors That Affect a Diamond's Apparent Size
Several design elements can help accentuate a diamond's apparent size, from a diamond's cut and shape to the setting and style of a ring.
A halo setting, which is a surrounding of diamonds or other stones around the center stone, is one way to accentuate the appearance of a center stone. A three-stone setting, where the center stone is accompanied by side stones, also adds a little extra sparkle, as does a pavé setting.
An oval diamond or gemstone with a longer form, can elongate the appearance of a ring.
But size is just one consideration. We always advise our clients to choose the style or shape that most appeals to them, and go from there.
