Natural vs. lab diamonds

Much has been written online already about the differences between lab and natural diamonds; if you’re interested in reading about the history and growing methods of lab diamonds, we recommend reading this short article by GIA.

Summerset makes luxury jewelry out of both natural mined diamonds as well as lab grown diamonds. Diamonds possess an inherent hardness and unique beauty, no matter their origin.

However, not all lab diamonds are equal. Just as there is a difference in the quality of diamond rough that comes from the Earth, the same is true of diamond rough grown in a lab, before it is cut and polished. Lower quality growth usually results in a gray or brown tint (which is not recorded on the diamond color scale), or cloudiness inside the stone. Summerset is committed to quality at every stage, and as such, we only work with top tier rough to ensure the best possible finished look.

Because the supply of lab diamonds is not inherently constrained in the way that mined diamonds are, lab diamonds are a more affordable option, making it possible to create, buy, and wear larger or more intricate fashion pieces.

All of our stones–lab and natural–are grown and sourced ethically and sustainably.

We always specify the type of diamond used in our pieces, so you can make the choice that’s right for you.
