Founder Story
I believe in following your dreams without making a bunch of tradeoffs.
So, when I learned that couples were putting off mortgages, travel, and other big dreams to purchase a diamond engagement ring instead, I knew that as a jewelry professional, I could help them do better.
I wanted to offer a premium alternative to natural diamonds, which are priced astronomically high and - contrary to popular misconception - don't make sense as investments. I value quality and wish to pass jewelry down to my daughter the same way my mom did.
That's why I started Plum Diamonds, to craft modestly priced, premium lab-grown diamond rings that will be treasured forever.
