buying diamonds

Now that you’ve discovered natural diamonds, you’re probably considering investing in your own. Here you will find valuable information to assist you on your journey to becoming a collector.

Important Factors to Consider

The greatest considerations when purchasing a natural diamond are that the primary color of the stone should be green, and the green color should be of natural origin. Below is a detailed discussion of all of the factors to consider when valuing a natural diamond.


When purchasing a green diamond it is important to know first and foremost where the diamond comes from, and whether it has been enhanced or treated.

A natural diamond should come directly from nature and should not be lab-enhanced or treated in any way. As a general rule, treated diamonds are valued significantly lower than natural, untreated diamonds.

This is because many stones can be treated to reach gem quality, but naturally occurring stones of gem quality are rare. Therefore, from a collector’s point of view it makes sense to err on the side of rarity to ensure the security of your natural diamond investment.

It is also important to verify that a natural diamond has been processed through Kimberly Process Certification (KPC) to ensure that it is conflict-free and is not a “blood diamond,” as well as GIA certified to ensure authenticity and value.
