In order to calculate the
diamond ratio, divide its length by width. For instance, a
diamond that is 5.5 millimeters long and 3.5 millimeters wide has a 1.57 length to width ratio.
When applied to an
oval diamond ring, this ratio is at its most appealing if they are chosen in between 1.30 to 1.50. Vintage
oval cut facets are appealing on the
ring finger. However, a touch thinner
diamond cut to that may look decorative in settings where
diamonds are sided by stones. That is why personal style preference is up to the wearer when it comes to buying
rings featuring an
oval cut diamond.
The
oval shape engagement ring hides the birthmarks and impurities of the
diamond. Next to the
rounded edge, or where jewelry
settings would lay, it is virtually implausible for onlookers to see inclusions of the
diamond. This is one of the reasons, why
diamond cutters suggest buying an
oval diamond ring with SI1 or S12 clarity when on a tight budget.
