Hello, Better Jewelry

Plum only works with lab grown diamonds because we believe they make better jewelry - you get bigger and better 4Cs without the trade-offs that come with mined diamonds. And of course, lab grown diamonds are friendlier to our environment and to our wallets.

Quality, Not Clutter

Quality first. Then curation, not clutter: we only make the industry's highest quality ring settings in thoughtfully designed, timeless styles, and our lab diamond selection is screened for the best stones. Not to mention, we make every ring to order in our own certified-sustainable facility with recycled metals and include free lifetime sizing and care.

Hi! I'm Kristy Cullinane, co-founder at Plum. My partners and I grew up in jewelry workshops and showrooms, helping couples from all walks find their forever rings. We've watched everyone we know fall for lab diamonds, ourselves included!

When I was getting engaged — being a jewelry industry veteran — I just knew that a "Conflict" diamond was off the table. I love lab diamonds because you can feel great about your ring now and forever — they're aligned with modern values and priorities.

The backbone of this company (our first-class manufacturing operation) has been making jewelry for 50+ years. Why should you care? Because we’re not a flash in the pan. We’ll be around for 50+ more, here for you down the road for your sizings, maintenance, and pro support.
