Natural vs Lab Diamonds

Natural Diamonds


Natural diamonds are rare and form deep in the earth's crust. When carbon is subjected to the extreme pressure and temperatures found at this depth, it crystalizes to form a diamond.

Our high quality selection of natural loose diamonds make for rare and exquisite heirloom centerpieces in many of our custom jewelry designs and engagement ring settings.

When to buy Natural

Natural diamonds are the preferred choice of those looking for a natural and rare stone to invest in. Natural diamonds are perfect for high quality custom designs, engagement rings and heirloom pieces of jewelry.

Lab Diamonds


Lab diamonds are genuine diamonds that are formed inside of a laboratory. By subjecting carbon to extreme pressure and heat it crystalizes to form a diamond without the need for mining.

Lab diamonds are growing in popularity which is contributed to both the current economy and marketing by major brands as a sustainable alternative to natural (although this is disputed).

Our high quality lab diamonds offer a more affordable alternative to their natural earth-formed counterparts.

When to buy Lab

Lab diamond are preferred by budget conscious shoppers and those who wish to decrease the impact diamond mining has on the earth. Lab diamonds are best for everyday jewelry containing larger or mutliple diamonds such as tennis bracelets or diamond stud earrings.

Natural vs Lab


Natural and laboratory formed diamonds are both genuine diamonds except for a few key differences which can be used to distinguish them.


Natural diamonds are more expensive and often make their way into higher quality pieces of jewelry. Lab diamond are more affordable and can now be found in many jewelry items on the market today.

Other differences

According to GIA: Laboratory-grown diamonds require advanced testing in a gemological laboratory to be identified with certainty. At laboratories like GIA, scientists and graders used sophisticated instruments to analyze diamond strain patterns, trace element composition, inclusions, fluorescence, phosphorescence and more in order to separate laboratory grown diamonds from natural. These factors are different due to the vastly different formation conditions of laboratory-grown and natural diamonds.
