A piece of glass on which the edge of a diamond is drawn, will be cut without much pressure; a slight blow is sufficient to separate the glass. An imitation may scratch the glass, but this will not be cut as with the diamond.
If a small drop of water is placed upon the face of a diamond and moved about by means of the point of a pin, it will preserve its globular form, provided the stone is clean and dry. If the attempt is made on glass, the drop will spread.
A diamond immersed in a glass of water will be distinctly visible, and will shine clearly through the liquid. The imitation stone will be confounded with the water and will be nearly invisible.
By looking through a diamond with a glass at a black point on a sheet of white paper, a single distinct point will be seen. Several points, or a foggy point will appear if the stone is spurious.
Hydrofluoric acid dissolves all imitations, but has no effect on true diamonds. This acid is kept in gutta-percha bottles.
For an eye practiced in comparisons it is not difficult to discern that the facets in the cut of a true diamond are not as regular as are those of the imitation; for in cutting and polishing the real stone an effort is made to preserve the original as much as possible, preferring some slight irregularities in the planes and edges to the loss in the weight, for we all know that diamonds are sold by weight. In an imitation, however, whether of paste or another less valuable stone, there is always an abundance of cheap material which may be cut away and thereby form a perfect-appearing stone.
Take a piece of a fabric, striped red and white, and draw the stone to be tested over the colors. If it is an imitation, the colors will be seen through it, while a diamond will not allow them to be seen.
A genuine diamond, rubbed on wood or metal, after having been previously-exposed to the light of the electric arc, becomes phosphorescent in darkness, which does not occur with imitations.
Heat the stone to be tested, after giving it a coating of borax, and let it fall into cold water. A diamond will undergo the test without the slightest damage; the glass will be broken in pieces.
Finally, try with the fingers to crush an imitation and a genuine diamond between two coins, and you will soon see the difference.
Take your stone to a local jeweler, who can use a probe to confirm that the stone is either a diamond, or not a diamond.
you could measure its specific gravity, and its refractive index - both are non-destructive tests. A gemologist would be able to answer about a particular stone.
Take the stone to a jeweler who can use a probe to determine whether the stone is a diamond or not.
Using a diamond probe, a jeweler can help you determine whether or not the stone you have is a diamond.
Take your stone to a local jeweler and ask the jeweler to verify that the diamond is a real diamond. The jeweler will use a device that measures electricity as it passes through the stone.
Take the raw stone to a jeweler who can apply a probe to the stone to determine whether or not it could be an uncut diamond.
No stone compares to a diamond.
The field test for diamond is hardness. You can take your stone to a local jeweler who can apply a probe and tell you whether or not what you bring in is diamond material or not.
diamond = cacbon + stone

i dont know so somebody else please answer im begging you
Diamond
Take your stone to a certified gemologist to confirm that it is a diamond. It could be a crystal stone of another type, and not a diamond. One reason why a diamond stone would appear hazy to the naked eye is because of flaws in the stone. If the stone is a diamond, it is probably not an expensive stone, given its apparent lack of clarity.
In general No. Why do you wanna wear diamond. If we know the reason, we can recommend other stone or remedy to benefit you.
Stone for stone, a diamond is more expensive than an emerald.
Stone for stone, a diamond will cost more than a sapphire.
