Faceting and polishing are two separate steps in the process of manufacturing a sale-able diamond from a raw stone.
However, early diamond fanciers -- beginning as early as 6,000 BC in India -- may have simply polished the existing four facets on a naturally-occurring, pyramid-shaped diamond stone and considered the stone 'finished'.
(History, however, brought diamond cutting -- faceting -- into the ever-developing story of diamond manufacturing.)
You can buy a 'diamond in the rough' ring from Nieman Marcus today that appears much like the early un-cut diamonds may have appeared centuries ago: link, below.
The side of a cut jewel is called a facet. Facets are flat, polished surfaces that are cut into a gemstone to enhance its brilliance and sparkle. The number and arrangement of facets can vary depending on the cut of the gemstone.

Should is an interesting word, and in this context doesn't mean much, until you expand the context of the query. If the jeweler is proving that the diamond is not on the list of stolen diamonds -- those listed with serial numbers, then, yes: the jeweler should show you the serial number on a diamond. If the jeweler wants to prove that a serial number exists on a diamond -- it cannot be seen with the naked eye -- then, yes: the jeweler should show you the serial number on a diamond. Otherwise, the situation requires a context.
'White' diamonds are graded in colour using letters of the alphabet, from D to Z, D being the highest grade. A number in a diamond's description can reference its weight in carats, or the number of visible flaws.
According to Wikipedia: "In diamond each carbon atom is at the centre of a tetrahedron formed by four other carbon atoms, so the coordination number is four..."
The smooth surface areas of a diamond that have been cut, polished and positioned are called facets. They allow light to enter and reflect back which gives it the brilliance, fire, sparkle and luster of a diamond. The number of facets a brilliant cut round diamond has is 58.If you add more facets to the crown you are actually compressing more facets into the same area and by doing so they would have to be smaller. Smaller facets mean smaller windows and less light. So having more extra facets isn’t a good idea.
The number of facets on a diamond stone are not considered when valuing a diamond.
The number of facets in a cut and polished diamond depends on the style of the cut, not of the carat weight of the stone. Except that the diamond cutter who planned and executed the cut, designed the cut to maximize the raw stone's clarity and colour, while preserving the carat weight.
The cut determines the number of facets on a diamond stone; radiant is a marketing adjective used to describe a brand of diamond.
The number of facets on a diamond is dictated by its size and the shape of the cut. For example, an emerald cut stone has 57 facets and a baguette cut stone has 25. The radiant cut has 70 facets. An 8/8 or single cut stone has 17 facets. When the symmetry of the facets is angularly perfect, the table of the stone delivers optimum luster for the stone.
Different cuts of diamonds are formed with a different number of facets. For example, a round cut diamond generally contains 58 facets. Depending on the raw stone, a different number of facets are cut, to show off the natural clarity or colour of the stone.
The side of a cut jewel is called a facet. Facets are flat, polished surfaces that are cut into a gemstone to enhance its brilliance and sparkle. The number and arrangement of facets can vary depending on the cut of the gemstone.
The number of facets is not a measurement that equates to mms.
The Asscher cut may vary in the number of facets, depending on the weight of the stone, who cut the stone and who is selling it. This cut is essentially a square emerald cut. You can read more about it, below.
You may be referring to a briolette cut. The number of cuts may depend on the size of the raw stone. Read more, below.
The price of every diamond is based on its individual carat weight, colour, cut and clarity. You've only given 14 cent -- referring perhaps to the number of 'points' or hundredths of a carat, on a cut and polished diamond.
A round brilliant cut stone weighing five carats measures about 11mm at the girdle. A rose cut diamond has fewer facets than a round brilliant, so this number can only be an estimate.
