What depth and table is ideal for a diamond?
For example, the best table and depth for round diamonds is a depth percentage between 62.9 and 59.5 percent and a table percentage between 63 and 56 percent. The best depth for diamonds with a princess cut is between 64 and 75 percent while its ideal table percentage is between 67 and 72 percent.
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.
Does diamond table make it look bigger?
Choose Your Diamond Shape Wisely Some diamond shapes have more mass on their table (the top of the diamond), which makes them look much larger per carat.
Is Depth important in a diamond?
Depth is important because it is one factor that contributes to the diamond’s overall cut grade. Diamonds with a lower depth percentage carry most of their weight on the top, which means the diamond will appear larger when you look down at it.
Can a diamond be too deep?
A diamond’s total depth or height is measured from the surface of the table to the culet, in other words, from top to bottom. When a diamond’s total depth is too high relative to the average girdle diameter, it is said that the diamond is too deep.
How do you measure the depth of a diamond?
The diamond depth ratio is calculated by dividing the height by the diamond’s width. In this context, the height is the jewel’s length from the top to the culet at its base. If a diamond’s height is 2mm and the width is 4mm, its depth is 50%.
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.
How can you tell if a diamond is too shallow?
What Is a Shallow Diamond Cut? When a diamond’s total depth is too low relative to the average girdle diameter, it is said that the diamond is too shallow or spread (spready).
What happens when a diamond is cut too deep?
When a diamond is cut too deep, light hits the pavilion at a sharper angle, causing it to immediately reflect to another pavilion. The light is forced to retract and pass through the bottom of the diamond. As this happens, light is dulled and the diamond becomes less vibrant and radiant.
Are shallow diamonds cheaper?
Although you may find spread diamonds that still exhibit good sparkle, the shallower the cut gets, the more light the stone loses and the less brilliance it retains. That’s why shallower stones have lower quality grades and are cheaper.
What is a diamond’s depth and table?
The values for the depth and table are measured in percentages. This is a good thing because percentages remain consistent regardless of a diamond’s size. Any diamond, from half a carat to the Hope Diamond, can have an ideal depth and table.
What is the best depth for a diamond?
The best depth for diamonds with a princess cut is between 64 and 75 percent while its ideal table percentage is between 67 and 72 percent. For oval diamonds, the ideal diamond depth is between 58 and 62 percent while the ideal table percentage is between 53 and 63 percent.
How deep should a princess cut diamond be?
For a princess cut diamond, choose a diamond with an ideal depth of 68 to 75 percent. Here’s a beautiful 1.10-carat princess cut with a depth of 73.3%. For a cushion cut diamond, look for an ideal depth that’s between 61 and 68 percent.
What is the Ideal table percentage for a diamond?
The ideal table percentage will vary based on the shape of your diamond. For example, the ideal table for round-cut diamondsis between 54-60 percent, while the ideal dimensions for emerald-cut diamonds puts table percentage between 66-72 percent.
