What is the best depth for a diamond?

How big should the table be on a diamond?
Generally, the best-looking diamonds have table sizes in the range of 55% to 60% (measured as a percentage of the diameter of the diamond). The size of the table is more important in larger diamonds, say over 1/2 ct. Variations in table sizes are less critical than crown and pavilion angles.
At what depth are diamonds found?
Most gem-quality diamonds come from depths of 150–250 km in the lithosphere. Such depths occur below cratons in mantle keels, the thickest part of the lithosphere.
Do you want fluorescence in a diamond?
Diamond Fluorescence and Near Colorless Diamonds
For nearly colorless diamonds in the G-H range, we recommend faint fluorescence at most. Faint fluorescence can have the benefit of bumping your diamond up one color grade, making your “near-colorless” diamond appear “colorless.”
Which cut of diamond has the most sparkle?
Round Brilliant is the most classic stone shape and is made up of 58 facets. Round engagement rings are by far the most popular of all the shapes as they’re the diamond cut that sparkles the most.

How important is table in a diamond?
The size of the table is one of the most important factors in the appearance of any diamond. A large table not only lets light into the diamond, but it also disperses light onto the other facets of the diamond to create a beautiful sparkle.
What setting is best for a round diamond?
Best Settings for Round Diamond Engagement Rings

Should a diamond have a Culet?
Since a large culet can negatively affect the appearance of a diamond, it’s best to stick to diamonds that have no culet. This is often referred to as a pointed culet, as the bottom of the diamond has a point instead of a flat surface. These grades all provide a diamond with optimal brilliance.
What is the best crown angle for a diamond?
The angle of the crown should be 32-35 degrees. If it is smaller than 32 degrees, the diamond is called a spread-cut. The table area is too large in a spread-cut diamond, and the girdle too thin, which cause the diamond to appear foggy, and the edges to be unprotected.
What makes a diamond sparkle?
What Makes a Diamond Sparkle? The short answer: light’s interaction with a diamond’s cut. … As you or the diamond moves, an effect called scintillation occurs – visible as alternating flashes of white and spectral-colored light and the contrast of dark and light that moves around the diamond.
