toroid
There are many possible answers. Some are: A sphere or ellipsoid sliced by two planes A cone sliced by two planes A toroid (doughnut) with a wedge cut out An infinite circular prism sliced by two planes.
The intersection of two ideal lines
Independent grading labs use different metrics to evaluate the cut. The scale from best to worst is: Ideal (AGS only) Excellent (AGS, GIA) Very Good (Most labs) Good (Most labs) Fair (Most labs) Poor (Most labs) Each grading lab has slightly different criteria, though it is generally accepted that AGS is the most strict followed by GIA then EGL, then any others as less strict (e.g. a "Very Good" from a less strict lab may be graded as a "Good" by a more strict lab). Many companies use the term "ideal" to describe their best diamonds they sell, though they may not actually be independently graded as "Ideal".
If the diamond is an ideal emerald cut with these measurements, the diamond may weigh about one quarter of a carat. Otherwise, you have stated the diamond's 'big' size in measurements.

A magnetic field for a toroid is typically concentrated within the coil, circling around the winding. Inside the toroid, the magnetic field lines are close together and form closed loops. Outside the toroid, the magnetic field is very weak and essentially negligible.
according to the ampere's law . magnetic field is strongest in a loop or a plane. and about toroid the magnetic is strongest in the coil where the wire is rotated around it . Magnetic field is minimum inside and outside the toroid.
A toroid is a doughnut shaped, three dimensional shape like an O ring. Any three dimensional shape can be rotated completely around an axis to create a toroid shape leading to toroids with both curved and flat faces.
toroid
A sphere, an ellipsoid, a toroid and many more.
Yes. A sphere, an ellipsoid, a toroid.
Wheel is a "Toroid" shape which is like a donut.
A sphere, an ellipsoid, a toroid are some examples.
The magnetic field inside a toroid is approximately zero due to the cancellation of the magnetic field produced by each winding of the coil. The field lines generated by current flowing in one direction on one side of the toroid cancel out with the field lines generated by current flowing in the opposite direction on the other side, resulting in a net field of close to zero inside the core.
These devices are not transformers, but toroid hall effect sensors. That is how they can sense DC.
