Q: How can I know if a diamond is real or fake?
In addition to high powered loupes, gemologists typically have a thermal conductivity probe or meter (aka "the diamond tester”). This tool is used to determine the thermal conductivity of a gemstone. Since diamonds are effective heat conductors, they disperse heat rapidly after being warmed. If you don't have access to a diamond tester, you can try the "Fog Test." This method has you hold the diamond (or ring) between two fingers and breath on it. The puff of air should produce a light fog on the surface of the diamond. If the fog evaporates right away, the diamond is likely authentic.
Q: What is more important, diamond clarity or color?
This question can be tricky, it depends more on the diamond shape.
Round Cut Diamond
Clarity: Inclusions are usually not noticeable in round diamonds, so buyers can go a bit lower on the clarity scale.
Color: Round diamonds reflect more light than other shapes because of the way they are cut. As a result, round diamonds are better at hiding low color grades.
Princess Cut Diamond
Clarity: Princess-cut diamonds also hide inclusions well, but because inclusions in the corners can make the diamond more susceptible to chipping, clarity is more important than color.
Color: It’s recommended that you don’t go below an I color grade if you are buying a princess-cut diamond.
