If you’ve spent any time on TikTok or Instagram over the last year, you’ve almost certainly seen someone unboxing a Quince lab diamond piece — a tennis bracelet, a pair of statement studs, an engagement ring that looks like it cost five times what it actually did. We’ve been watching this brand for a while, we’ve bought from it ourselves, and we are, without exaggeration, huge fans of these diamonds. Huge

This is our full, honest breakdown of Quince lab grown diamonds — what they are, why they’ve become one of the most talked-about jewelry lines in the direct-to-consumer space, every product currently worth knowing about, and why we personally think this brand has completely changed how we think about buying diamonds.

Our Story: From a Halo Ring in San Francisco to a Quince Diamond Obsession

A little backstory, because it’s actually the whole reason we started paying attention to lab grown diamonds in the first place. When my husband and I bought our engagement ring years ago, we went to Shreve & Co. in San Francisco — one of the city’s oldest and most iconic jewelers. At the time, halo engagement rings were the style everyone wanted: a center stone surrounded by a ring of smaller pavé diamonds, designed to make the whole thing look bigger and catch more light. We picked one out, and it felt timeless.

Fast forward to today, and here’s the funny thing — nearly all of my friends now have a ring that looks almost identical to mine. The halo setting has had such a long, sustained moment that what once felt like a personal, considered choice now feels like it’s everywhere. It’s not a bad thing exactly, it’s just made me start wanting something different — something that feels like mine again.

That’s part of why the idea of a Quince lab diamond ring has been so appealing to me lately, specifically as a travel piece. I don’t want to take my actual engagement ring on vacation — too much risk, too much anxiety about losing it or damaging it on a hike or in the ocean. But I also don’t want to travel with something that looks cheap. A lab grown diamond ring from Quince solves that problem in a way nothing else really does: real diamonds, real gold, a fraction of the cost, and genuinely low stress if something happens to it.

And then there’s the piece that actually turned me into a full-blown Quince evangelist: I bought myself the 14K Gold Lab Grown Diamond Solitaire Pendant in 2ct as a birthday gift last year. I have never — and I mean never — received more compliments on a single piece of jewelry in my life. Strangers stop me. Friends ask where it’s from constantly. For a pendant that costs a fraction of what a natural diamond of the same size would run, the compliment-to-dollar ratio is honestly unmatched.

What Are Lab Grown Diamonds, Exactly?

Before getting into the products, it’s worth answering the question everyone asks first: are lab grown diamonds real diamonds?

Yes. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds — same carbon structure, same hardness, same brilliance. The only difference is where they’re created: instead of forming underground over billions of years, they’re grown in a controlled lab environment using extreme heat and pressure (or a vapor deposition process) that replicates the same natural conditions. A gemologist needs specialized equipment to tell a lab diamond apart from a mined one — the naked eye absolutely cannot.

The big difference that actually matters to shoppers is price. Because lab diamonds skip the mining, cutting, and global supply chain markup of the traditional diamond industry, they typically cost 60–80% less than a mined diamond of the same size and quality. That’s the entire reason brands like Quince have been able to make genuinely large, genuinely impressive diamond pieces accessible at a price point that used to only get you a fraction of the carat weight.

Why Quince Specifically? Quince vs. Other Lab Diamond Brands

Quince built its whole business model around cutting out the traditional retail markup — selling directly to consumers instead of through department stores or licensing arrangements, which is the same model that’s made its clothing and home lines so popular. Applied to fine jewelry, that means:

Significant savings vs. traditional retailers. Comparing similar lab-grown pieces, Quince has been shown to run roughly 60–70% less than comparable pieces at retailers like Blue Nile for similar carat weight and gold quality.

Transparency about lab-grown vs. natural. Quince is upfront on every product page about whether a stone is lab-grown or natural — which matters, because some retailers have been called out for burying that detail until checkout.

14K gold settings, which is the industry-standard durability sweet spot between softer 18K gold and less premium 10K.

A genuinely wide price range, from under-$400 diamond huggie hoops all the way up to five-figure engagement rings and tennis necklaces — which means the brand works as an entry point into fine jewelry, not just a destination for big purchases.

The most common critique we’ve seen in independent reviews is that Quince uses a fairly minimal amount of gold in some settings to keep costs down — worth knowing, but not something that’s stopped us (or seemingly anyone else) from being obsessed with the actual diamonds.

The Halo Ring Question: Why I’m Considering a Quince Diamond for Travel

Coming back to where this all started — I still love my original halo engagement ring. That’s not changing. But between how ubiquitous the halo setting has become among my friend group and the simple practicality of not wanting to fly, hike, or swim with my actual engagement ring, a Quince lab diamond ring feels like the obvious answer. It gives me a completely different silhouette to wear day-to-day (hello, oval and cushion cuts) while keeping my real ring safely at home when I travel. It’s not a downgrade — it’s a genuinely smart, low-stress way to still wear something beautiful without the constant low-grade anxiety of “did I just lose a five-figure ring in the ocean.”

Frequently Asked Questions About Quince Lab Diamonds

Are Quince lab grown diamonds real diamonds? Yes. They’re 100% real diamonds, chemically and physically identical to mined diamonds — just grown in a lab rather than the earth.

Are Quince diamonds certified? Quince’s lab grown diamonds are typically graded and certified, so you’re not just taking the brand’s word for the quality — always check the specific certification details on the product page before purchasing.

How much cheaper are Quince lab diamonds than natural diamonds? Generally in the range of 60–80% less than a comparable natural diamond of the same size and clarity, and independent comparisons have found Quince specifically runs significantly below other lab-diamond retailers as well.

Do lab grown diamonds hold their value? Lab grown diamonds do not appreciate the way natural diamonds are sometimes marketed to (a claim that’s debated for natural diamonds too). Most people buying lab grown diamonds are doing so for the look and value at the point of purchase, not as an investment vehicle — which, honestly, is a more honest way to think about diamond jewelry in general.

Bottom Line

We came into this as halo-ring loyalists who never thought much about lab grown diamonds, and we’re leaving it as genuine, enthusiastic Quince lab diamonds fans. Between the tennis bracelets, the statement studs, the new huggie hoops, and especially that 2ct solitaire pendant that hasn’t stopped getting compliments since the day I put it on, this is one of the very few jewelry brands we’d tell every single friend to check out before their next big (or small) diamond purchase.
