This is the shape of the diamond, and can be established with the naked eye.
A round stone has 58 facets, which must be in perfect proportion, ensuring light is reflected to the top of the stone. This gives the stone its beautiful ‘life’.
The original shape of the rough stone often determines the shape of the cut and polished diamond, e.g. pear shape.
The number of facets of fancy shaped stones may vary.
This refers to the weight of the diamond.
The carat reading of a stone is also an indication of its size although it is actually a measure of weight.
1 Carat = 100 points = 200 milligrams = approximately a 6.5 mm round stone.

A .75 or a 3/4 carat stone is the same as a 75 "points".

The perfect white stone has no colour, and is graded as D.
Going down the alphabet, between D to J, stones are graded as white.
From K to Z, a yellowish tint may be detected. Jewellery stone technically often have a hint of colour, which makes it more affordable, although it looks white to the naked eye.

Yellow / Red gold: H, I, J, K, or better.
