  2. Material properties of diamond - Wikipedia

    en.wikipedia.org/wiki/Material_properties_of_diamond

    The former property means a drop of water placed on a diamond forms a coherent droplet, whereas in most other minerals the water would spread out to cover the surface. Additionally, diamond is unusually lipophilic, meaning grease and oil readily collect and spread on a diamond's surface, whereas in other minerals oil would form coherent drops.

  3. Diamond (gemstone) - Wikipedia

    en.wikipedia.org/wiki/Diamond_(gemstone)

    A diamond with facets cut only a few degrees out of alignment can result in a poorly performing stone. For a round brilliant cut, there is a balance between "brilliance" and "fire". When a diamond is cut for too much "fire", it looks like a cubic zirconia, which gives off much more "fire" than real diamond. A well-executed round brilliant cut ...

    A diamond simulant is a non-diamond material that is used to simulate the appearance of a diamond, and may be referred to as diamante. Cubic zirconia is the most common. The gemstone moissanite (silicon carbide) can be treated as a diamond simulant, though more costly to produce than cubic zirconia.

  5. Sharpening stone - Wikipedia

    en.wikipedia.org/wiki/Sharpening_stone

    Over time diamond stones will wear out and need to be replaced. The lifespan can be extended by using light pressure and allowing the stone to work. The highest quality diamond sharpeners use monocrystalline diamonds, single structures which will not break, giving them an excellent lifespan. These diamonds are bonded onto a precision ground ...

    Diamond polisher in Amsterdam. Polishing is carried out by forcing a diamond against a spinning disk with abrasive. Diamond polishing is the final polishing of the diamond. In a diamond factory, one would find a diamond crossworker who first places the main facets on a diamond (blocking the diamond). This is done to ensure maximum weight ...

    They do not have to be protected from burning, like a diamond (although the stones do need to be protected from heat stress fracture by immersing the part of the jewelry with stones in the water when metal parts are heated).

  8. Herkimer diamond - Wikipedia

    en.wikipedia.org/wiki/Herkimer_diamond

    Because the first discovery sites were in the village of Middleville and in the city of Little Falls, respectively, the crystal is also known as a Middleville diamond or a Little Falls diamond. [ 3 ] Herkimer diamonds became widely recognized after workmen discovered them in large quantities while cutting into the Mohawk River Valley dolomite ...

  9. Paradox of value - Wikipedia

    en.wikipedia.org/wiki/Paradox_of_value

    In explaining the diamond-water paradox, marginalists explain that it is not the total usefulness of diamonds or water that determines price, but the usefulness of each unit of water or diamonds. It is true that the total utility of water to people is tremendous because they need it to survive; however, since water is in such large supply in ...
