Nowadays, Diamond Jewelry is not only open to Rich people, and in jewelry market, you can find many ornaments marked with Diamond, if you are going to take a diamond jewelry, then you should know how to identify the real diamond. Here are some tips for you.

1. Diamonds can be identified by their high thermal conductivity. Their high refractive index is also indicative, but other materials have similar refractivity.
2. Diamonds cut glass, but this does not positively identify a diamond because other materials, such as quartz, also cut it.
3. Diamonds can scratch other diamonds, but this can result in damage to one or both stones. Hardness tests are infrequently used in practical gemology because of their potentially destructive nature. The extreme hardness and high value of diamond means that gems are typically polished slowly using painstaking traditional techniques and greater attention to detail than is the case with most other gemstones; these tend to result in extremely flat, highly polished facets with exceptionally sharp facet edges.
4. Diamonds also possess an extremely high refractive index and fairly high dispersion. Taken together, these factors affect the overall appearance of a polished diamond and most diamantaire still rely upon skilled use of a loupe (magnifying glass) to identify diamonds ‘by eye’.
