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 insane 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, founder of Her Fifth Carat.

At nine years old, I was diagnosed with cystic fibrosis and told I likely wouldn’t live past 25. For most of my life, I struggled to picture a future beyond the immediate. Marriage, milestones, forever kind of love. They felt distant, almost indulgent, when time never felt guaranteed.

Then I turned 25.

Two months later, I met the man I would marry. Today, at 27, I often say I’m living my bonus scenes. Every chapter since has felt intentional, earned, and deeply meaningful.

When I began researching engagement rings, I immersed myself in understanding the lab diamond industry from the inside out. It quickly became clear how significant traditional retail markups were, and I saw an opportunity to build something more transparent and design-focused.

I knew there had to be a better way.

What started as deep research and personal passion has since evolved into a dedicated team committed to craftsmanship, quality control, and elevated client experience. Today, I lead a growing brand that works alongside skilled manufacturing partners and gem professionals to create exceptional lab diamond pieces with precision and care.

Her Fifth Carat was founded with a clear mission: to redefine the engagement ring experience. This brand is not simply about selling jewelry. It is about creating high quality pieces through transparency, elevated design, and a client experience rooted in trust.

I was once told I didn’t have time. Now I build timeless pieces for people celebrating forever.

Welcome to Her Fifth Carat.

Yes. Unless otherwise states, all center stones that are 1ct and above come with an independent IGI grading certificate confirming they are lab grown and outlining the cut, color, clarity, and proportions. Smaller diamonds used in wedding bands or hidden halos are considered melee stones and are not individually certified, which is standard across the jewelry industry.

First, we finalize your design direction and key details to ensure everything is aligned. Once payment is secured, a custom CAD rendering is created based on the approved design. You’ll have the opportunity to review the CAD and request minor refinements before we proceed.

For custom rings featuring a center stone over 1ct, we will also provide a video and certification of the selected diamond for your review. Both the CAD and the diamond must be approved by you before the piece enters production.

For all orders, once production begins, no further changes can be made.

Absolutely. Before production begins, you will be presented with diamond options that match your selected criteria. You’ll have the opportunity to review the specifications and approve the exact stone before it is set into your ring.

For ready-to-ship pieces, the diamond is preselected and included as listed. We recommend reviewing the product details carefully prior to purchase to ensure it aligns with your preferences.

CAD is used to finalize and refine an agreed-upon design, not to explore completely different ring concepts. We work closely with you beforehand to narrow down your direction so the CAD stage is focused and intentional.

Production timelines vary depending on the complexity of the design, but most custom pieces take 6-10 weeks to complete. We prioritize precision and craftsmanship over rushing the process. You will receive updates throughout production. For our collection pieces, timeline will be specified in product listing.

Once a ring enters production, adjustments cannot be made. We ensure all details are confirmed prior to beginning to avoid any issues. Please ensure your ring size is professionally confirmed prior to placing your order. Because each piece is custom made to your specifications, we do not offer refunds due to incorrect ring size provided at the time of order.

Carat weight, color, clarity, band width, metal type, and additional custom elements all significantly affect pricing. For example, increasing band thickness substantially increases gold weight, which impacts cost.

Diamond and precious metal markets fluctuate. Updated pricing reflects current costs at the time of order. Our custom quotes are valid for 7 days.

14k gold is more durable and better suited for everyday wear, especially for hands-on lifestyles. 18k has a slightly richer gold tone but is softer. We’re happy to guide you based on your lifestyle and preferences.

That depends on the design. Low-set styles may create a small gap unless specifically designed to sit flush. We can structure the ring intentionally based on your preference.

Yes. All orders are shipped with full shipping insurance and include tracking information. A signature is required upon delivery to ensure the package is received safely.

For added security, all orders are shipped in discreet packaging. Our business name is not displayed on the exterior of the box to help prevent theft or unwanted attention.
