There is a myriad of ways to test the likelihood of whether a diamond ring is the real thing. Here are just some of them which when practised will tell you everything you need to know about identifying a fake diamond ring from a genuine example.
The Fog Test
Whilst some of the most commonly used tests to expose a fake diamond involve looking at a loose diamond, this is one which can be used to test the authenticity of a diamond once it has been cast in metal as part of a jewellery piece. It is also one of the most simple and quick tests to determine if what you are holding is the real deal. Hence, it is a test worth carrying out.
Simply breathe onto the diamonds surface to create a mist. If the mist lingers more than a few seconds this is a sure indication that what you have breathed upon is not a diamond. Diamonds are excellent heat conductors. Hence, a mist should disperse from the surface of a true diamond very quickly.
If you have, to hand, a genuine diamond ring and another ring bearing a clear stone which is not a diamond, give the test a go to familiarise yourself with how the two react. Provided one is a genuine diamond ring and one is not, the difference should be instantly clear to you.
Many diamonds and certainly the most expensive examples are sold with something called a diamond certificate or report. Diamond certificates or reports are provided by a gem grading authority after closely inspecting a diamond.
The report or certificate which is issued as a result of a stone having undergone an accredited gemmologists scrutiny in a laboratory will feature a wealth of information as to the shape, cut style, age, origin, carat weight, symmetry, clarity and polish of a diamond amongst other things.

Settings and Metals
Whilst loose diamonds in many ways are far easier to inspect, a diamond already set in metal does enable a person to inspect the setting itself to help assess the authenticity of the piece, as well as its age. High carat gold or platinum settings are often used in creating diamond rings and indicate that the stone(s) they bare are too the real thing. If the nature of the metal in which a stone supposing to be a diamond is set is a valuable metal, it is far more likely that the stone itself is too genuine. In contrast, if the metal is of a poor quality or fake this is an almost guarantee that so is the stone it holds.
Antique Diamond Rings
Settings are particularly useful to inspect when assessing the authenticity of an antique diamond ring as diamonds, being one of the hardest materials known to man, are likely to have withstood the test of time with minimal, or in fact no obvious signs of wear and tear.
Meanwhile, their settings are less likely to have survived so well or to look so immaculate after over 100 years. Hence, coupled with the cut of the stone which will help to age the piece, the setting its condition and the stones condition should all come together to result in a piece which appears of its supposed age.
Through the Looking Glass
Use a loupe to look for slight imperfections. No stone is perfect. Therefore, a diamond that looks too good to be true probably is.
Further, when diamonds are cut their girdle or the edge created around the circumference of a stone will, under a loupe, appear frosted. In contrast, many of the stones used to commonly create fakes, such as cubic zirconias will bare perfectly crisp, neat edges.
Whilst using a loupe it is also worth taking a closer look at the colours the stone reflects. A true diamond will reflect varying shades of grey, not all the colours of the rainbow. This is an attribute of genuine diamonds. Hence, a clear stone which reflects numerous colours is definitely not a diamond.
