Lab Diamond Engagement Rings

The moment is right. The love is real. What better way to make your proposal more special for your future bride than with a ring that embodies promise, brilliance, and love?

Lab-grown diamonds are gaining popularity among modern romantics, offering a cost-effective alternative that does not compromise sparkle or quality compared to mined ones.
They are identical in sparkle, strength, and beauty — just without the environmental cost.

Younger couples who are eco-conscious prefer lab-grown diamonds, as they can be found for up to 60% less than comparable mined diamonds.

Karaters lab diamonds are ethically grown, 100% conflict-free, and make undeniably stunning engagement rings to tell your love story. Based in the USA, we ensure that each ring or item that leaves our facility undergoes a 3-person quality check to minimize complaints.
