By faces, one must assume that you mean facets.
The brilliant cut, according to Wikipedia:
"The original round brilliant-cut was developed by Marcel Tolkowsky in 1919. The modern round brilliant consists of 58 facets..."

Uncut diamonds are not any particular shape, though diamond crystals are often octahedra. Cut diamonds usually have a lot more than 8 faces. The most popular, the brilliant cut, has 57 or 58 faces.
The faces of a diamond are typically referred to as facets. The most common cut, the round brilliant, has 58 facets, including the table (the flat top), the crown (the upper portion), and the pavilion (the lower portion). Other popular cuts, like the princess or emerald cut, also have their own specific arrangements of facets, but they share these basic components. Each facet plays a crucial role in the diamond's brilliance and overall appearance.

The smallness of the critical angle Θc for diamond means that light is easily "trapped" within a diamond and eventually emerges from the many cut faces. This makes a diamond more brilliant than stones with smaller n and larger Θc. Traveling inside a diamond, a light ray is incident on the interface between diamond and air.
No, this is because clubs with two striking faces are banned. So no, it cannot be used even if classed as two clubs. There is an exception to this rule, and that is putters with two striking faces.
I deleted the answer. In your faces.

Diamond is the hardest gemstone with hardness being 10. But hardness varies at octahedral faces of diamonds. So a diamond can only be scratched by a diamond itself.

As a 2d object, a diamond had four sides. As a 3d object, there are many different types of diamonds, all with their own numbers of vertices, edges and faces.
Sparkling with luster; glittering; very bright; as, a brilliant star., Distinguished by qualities which excite admiration; splendid; shining; as, brilliant talents., A diamond or other gem of the finest cut, formed into faces and facets, so as to reflect and refract the light, by which it is rendered more brilliant. It has at the middle, or top, a principal face, called the table, which is surrounded by a number of sloping facets forming a bizet; below, it has a small face or collet, parallel to the table, connected with the girdle by a pavilion of elongated facets. It is thus distinguished from the rose diamond, which is entirely covered with facets on the surface, and is flat below., The smallest size of type used in England printing., A kind of cotton goods, figured on the weaving.
A diamond (not dimond) has 1 face, 4 sides and 4 vertices.
If the diamond is cut, then the answer to this question depends entirely on how it was cut.However, the natural shape of a diamond crystal is octahedral (eight sided). It would look like two pyramids with their bases glued together. This gives eight faces, 12 edges and six verices.
