The fourth 'C', Color, is not characterized by the color of the diamond, as you might expect, but instead its colorlessness.
To this end, the GIA has developed a color scale which categorizes gemstones according to their color grading.The less discoloration the diamond has, the stronger its light reflection and the more the diamond’s overall sheen are. If the diamond is to be considered an investment, we recommend investing in those from the D, E, F, G o der H color scale. It is crucial that investors check the quality criteria described above before buying and request a GIA certificate for the diamond. Such certificates list all the diamond’s characteristics and is an absolute must for security reasons and resale.
Risks in investing in diamonds are considered rather low as a total loss remains impossible as is the case with stocks. A diamond’s loss of value would only result from actually misplacing the gemstone or turning it into and individual piece of jewelry. As such, this investment remains one of the only wearable ones in existence and one you can always choose to sell at a later date. Don’t forget, a diamond can always become a precious heirloom that appreciates as it is inherited through generations.
