About Us

The Fifth C That Changes Everything

Her Fifth Carat was born from a simple but powerful idea: dream rings shouldn’t come with a nightmare price tag.

We source certified lab-grown diamonds and create custom jewelry without the retail markup,  helping you save thousands while still getting the one.

Whether you're shopping for a loose lab diamond, an engagement ring, a pinky stack, or a forever piece just for you, we make the process feel personal, transparent, and actually fun.

You know the 4 Cs of diamond shopping... we're your fifth.

Meet the Founder

Hi, I’m Lex — the girl behind Her Fifth Carat.

When I was 9 years old, I was diagnosed with cystic fibrosis. Doctors told me I wouldn’t live past 25.

So for most of my life, I didn’t let myself dream too far ahead. Marriage? A future? A forever kind of love? I thought wanting that would be selfish because I wasn’t sure I’d be around to stay.

But then I hit 25.

And two months later, I met the love of my life. I’m 27 now, engaged, healing, and living what I call my bonus scenes.

When we started researching rings a year before we got engaged, I went deep down the lab diamond rabbit hole. I learned how insane the markups were at traditional jewelry stores. I spent months connecting with suppliers and learning the ins and outs of lab diamonds. I started sourcing pieces for myself, then for friends, and then for strangers on the internet who wanted something beautiful without getting ripped off.

Her Fifth Carat started as a passion project but it was never just about rings. It’s about rewriting the story you thought you had to settle for. I created this to help other women get the ring they deserve, without the markup, without the stress, and without wondering if they’re being scammed. 

I was told I didn’t have time. Now I'm here to help you design pieces that are timeless.
