Cut describes the proportions and angels of a diamond. Many people confuse cut with the shape of a diamond. Although nature determines the other three characteristics, it takes a master diamond cutter to reveal a diamond’s true beauty. Diamonds are available in various shapes including round, square, pear, heart, marquise and oval but cut refers to the angels and proportions of a diamond.
A well cut diamond reflects light from one mirror-like facet to another and projects the light through the top of the stone. The result is a fiery and brilliant display. Diamonds that are cut too deep or too shallow leak light through the side or bottom, resulting in a lackluster appearance and diminish value.
Nature ensures that each diamond is as individual as the person who wears it. Naturally occurring inclusions such as minerals or fractures are identifying characteristics created while diamonds are formed in the earth. Master IJO Jewelers use magnification to view diamonds at 10x their actual size so these tiny inclusions are more easily seen.
Inclusions are measured on a scale of perfection, known as clarity, which was established by GIA. The greater a diamond’s clarity, the more rare and valuable it is. A diamond with an inclusion in the middle or top could impact the dispersion of light, making the diamond less brilliant
