Lab-Grown vs. Natural Diamonds: What's the Difference?

Lab-grown and natural (mined) diamonds look the same, wear the same and are graded on the same 4Cs. Here's how they compare.

Lab-grown diamond Natural diamond
What it is Real diamond, grown in a lab Real diamond, mined from the earth

Disclosure Must be labeled lab-grown Sold as "diamond"

Can you tell them apart?

Not by eye. Telling a lab-grown diamond from a mined one requires specialized laboratory equipment. That's why disclosure and grading reports matter.

Which should you choose?

If you want the most diamond for your budget, lab-grown is the clear choice. If having a stone formed in the earth matters to you, choose natural. At Jewelexcess, lab-grown pieces always say "Lab-Grown" in their name, and pieces with natural diamonds simply say "Diamond."
