Precious stones and gems are usually charachterized by Clarity, Hardness and size. Wurtzite boron nitride is the hardest gem recently beating Diamond by 18% although Diamond is rated 10 on Moh's Scale the clarity and carat wieght determines price
You can check the authenticity of a diamond by looking at its certification, which provides details on the diamond's characteristics and origin. Another way is to consult with a professional gemologist who can perform tests such as a thermal conductivity test or inspect the diamond under a loupe for inclusions and other unique characteristics of a real diamond.
A certified diamond is one that has been evaluated by a professional in whatever certification method is documented by the certificate. For example, the Gemological Institute of America -- GIA -- certifies diamonds by documenting the colour, clarity, cut and carat weight of the diamond. This establishes the individual characteristics of the gem. A non-certified diamond can only be evaluated according to the expertise of the person evaluating the diamond, and usually without certification. It's characteristics, therefore, are uncertain.
Hallmarks on a diamond are specific markings or inscriptions made by diamond grading laboratories to verify the authenticity and quality of the stone. These hallmarks can include the laboratory name, the diamond's unique identification number, and other relevant information about the diamond's characteristics. They provide a reliable way to trace a diamond's origin and ensure transparency in the diamond industry.
Jewelers use a combination of methods to determine if a diamond is real. They typically examine the diamond under specialized lighting conditions to check for certain physical properties such as light reflection and refraction. They may also use magnification tools to examine the diamond for inclusions or other identifying characteristics. Additionally, some jewelers may use electronic diamond testers that measure thermal conductivity to quickly confirm the authenticity of a diamond.
A diamond is made up of carbon atoms arranged in a crystal lattice structure. This composition gives diamonds their hardness, brilliance, and ability to disperse light, making them highly valued gemstones. The purity, clarity, and cut of a diamond also contribute to its unique characteristics and value.

The opposite of opal does not have a universally recognized term. However, some may consider diamond, as they are both precious gemstones but with very different characteristics.
A 'transitional' diamond is probably a diamond given with the intention of replacing it with a larger stone at some point in the future. This is an emotional designation, not a gemstone designation.
A raw diamond has these geometric characteristics: its crystal habit is octahedral, and its crystal system is isometric-hexoctahedral (cubic).
A certified diamond is one that has been evaluated by a professional in whatever certification method is documented by the certificate. For example, the Gemological Institute of America -- GIA -- certifies diamonds by documenting the colour, clarity, cut and carat weight of the diamond.

The ratings for diamonds are determined by 5 different things. The diamond cut, clarity, color, weight and finally the diamond certificate which lists all the unique individual characteristics.
Any diamond is 'good' when it can be certified as to its characteristics: cut, colour, carat weight and clarity. A certified gemologist can perform this work for you.
Elements that have some characteristics of a metal and some characteristics of a nonmetal are called semimetals or metalloids.

The grading report or the diamond certificate enlists the individual characteristics of a particular diamond stone. To ensure the genuineness of diamond jewelry, it is important to demand its grading report from the seller before buying.
