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..."

In square close-packed layer, a molecule is in contact with four of its neighbours. Therefore, the two-dimensional coordination number of a molecule in square close-packed layer is 4.
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.
If the diamond has a serial number -- not all diamonds do -- you are most likely to find it engraved on the girdle of the stone.

coordination number in bcc is 8 coordination number in simple cubic is 6
BaCl2 should have the Fluorite structure, along with CaF2 and PbO2.The cation coordination number is 8The anion coordination number is 4
Coordination number of an ion is the number of oppositely charged ions present around that ion as the neighbour ions , in that ionic crystal.
The oxidation number of rhodium in a coordination compound can vary, but it is commonly found in the +2 or +3 oxidation state. The coordination number of rhodium in a coordination compound is typically 6, as it can coordinate with up to six ligands.
The coordination number is six for Na in NaCl.The coordination number is eight for Cs in CsCl. The accepted explanation is that the ionic radii of cesium and chloride are very similar.
The coordination number of copper typically ranges from 2 to 6 in its common compounds. In most cases, copper exhibits a coordination number of 4 due to its d10 electron configuration.

The coordination number in an ionic crystal refers to the number of ions closely surrounding a central ion in a regular geometric arrangement. It indicates the effective number of nearest neighbors for an ion within the crystal lattice. Different crystal structures may have different coordination numbers.
The coordination number of phosphorus can vary depending on its oxidation state and the molecules or ions that it is bonded to. In most common cases, phosphorus can have a coordination number of 3 or 5 in various chemical compounds.

In cesium chloride crystal, cesium ions have a coordination number of 8, as they are surrounded by 8 chloride ions. On the other hand, chloride ions have a coordination number of 8, as they are surrounded by 8 cesium ions.
