At Haejin Jewelry in Williamsburg, we craft custom lab-grown diamond rings and fine jewelry that align with the FTC’s definition of real diamonds, pairing modern science with Brooklyn artistry.

Why couples choose us: Haejin Jewelry has become one of Brooklyn’s most trusted destinations for lab-grown diamond engagement rings, serving NYC locals and international visitors who want a studio rooted in honesty, sustainability, and woman-owned craftsmanship.
For decades, couples have wondered: Are lab-grown diamonds real? In 2018, the Federal Trade Commission (FTC), America’s consumer-protection agency, answered with certainty. After reviewing its Jewelry Guides, the FTC removed the word “natural” from the legal definition of a diamond, declaring that lab-grown diamonds are real diamonds.
At Haejin Jewelry in Williamsburg, Brooklyn, we honor this truth every day by handcrafting lab-grown diamond engagement rings and fine jewelry that combine scientific integrity with Brooklyn artistry. This guide explains what the FTC ruling means, why it matters to New York couples, and how sustainable diamonds are redefining modern luxury.
Quick answer: Are lab grown diamonds real?
Yes. According to the Federal Trade Commission (FTC), lab grown diamonds are real diamonds with the same carbon structure, brilliance and fire as mined stones. The only difference is origin.
For couples in Brooklyn and New York City, that means you can choose a lab grown diamond engagement ring with full confidence that it is a true diamond, not an imitation.

- The FTC removed the word “natural” from the definition of a diamond, confirming that lab grown stones are legally recognized as real diamonds.
- Lab grown diamonds share the same optical, physical and chemical properties as mined diamonds, so you get true diamond brilliance and durability.
- Brooklyn and NYC couples can choose lab grown engagement rings that align with their ethics without sacrificing beauty, quality or meaning.

Who finds us in Brooklyn: Many of our clients visit from Williamsburg, Greenpoint, Bushwick, Manhattan, and from cities around the world while they are in New York. They come to our quiet studio at 123 Skillman Ave STO to choose or design a lab-grown diamond engagement ring that feels honest, modern, and deeply personal.
The FTC’s Official Decision: Lab-Grown Diamonds Are Real
“A diamond is a mineral consisting essentially of pure carbon crystallized in the isometric system. These stones have essentially the same optical, physical, and chemical properties as mined diamonds. Thus, they are diamonds.”
Federal Trade Commission, 2018 Jewelry Guides Revision
Before 2018, the jewelry trade limited “real” diamonds to those mined from the earth. The FTC’s clarification removed that bias, confirming that laboratory-grown diamonds share the same atomic structure, brilliance, and permanence as mined stones. It was a victory for truth, science, and conscious luxury.

The Science Behind Lab Diamonds
Lab-grown diamonds are created using advanced methods that replicate the Earth’s natural process:
- HPHT (High Pressure High Temperature): replicates the deep-earth environment where natural diamonds form.
- CVD (Chemical Vapor Deposition): grows diamond crystals layer by layer in a controlled chamber.
The result is a diamond that is chemically, physically, and optically identical to a mined stone. Both are graded by world-renowned laboratories such as GIA, IGI, and GCAL, and both register as diamonds on professional testers.
For couples in Brooklyn and New York City, this means access to pure, brilliant diamonds that honor both artistry and ethics. Design your own with our Ring Builder, or browse fine jewelry made in Brooklyn.
Why this matters for Brooklyn couples: As one of the few woman-owned fine jewelry studios in Williamsburg dedicated to lab-grown diamonds, Haejin Jewelry helps New York couples understand the science behind every stone so their ring feels intelligent, ethical, and emotionally true.

Top 5 Reasons the FTC Ruling Matters for New York Couples
For couples navigating the vibrant New York jewelry landscape, the FTC ruling is more than a legal footnote. It is a turning point that clarifies what “real” means and gives you power, protection, and peace of mind as you choose the diamond that will represent your love story.
- Real means real, not mined. The FTC has affirmed that lab-grown diamonds are genuine diamonds, not imitations or simulants. This means you can choose a lab-grown diamond with full confidence that you are getting authentic brilliance, durability, and beauty, regardless of whether it came from a mine or a lab.
- You are protected from misleading claims. By removing the word “natural” from the legal definition of a diamond, the FTC has made it harder for deceptive marketing to blur the lines between mined and lab-grown stones. Jewelers must be clear and honest in how they describe diamonds, which protects you from paying a premium based on outdated language or misinformation.
- You can align your values with your jewelry. If you care about the environment, labor practices, or resource use, the FTC ruling supports your ability to choose ethically. It recognizes lab-grown diamonds as legitimate, so you can prioritize sustainability and transparency without sacrificing quality or romance.
- Your budget goes further without compromise. Because lab-grown diamonds typically offer more carat weight and higher clarity for the same budget, the FTC affirmation helps you feel secure in choosing them. You are not “settling”; you are selecting a fully real diamond that allows you to invest more in the details that matter, from larger carat sizes to more intricate settings.
- It validates a new era of modern luxury. The ruling signals a broader cultural shift: the most meaningful luxury is not about tradition at any cost, it is about thoughtful choices that reflect who you are. For New York couples rewriting the rules of love, the FTC’s stance affirms that lab-grown diamonds belong at the center of your story, not on the sidelines.
