Key Features

• IGI Certification: Each lab grown diamond is independently verified by the International Gem Institute, confirming its exact carat weight, color grade, clarity, and cut quality. This certification ensures complete transparency and trust, giving you confidence in every detail of your purchase.
• Lab Grown Diamond: A real, genuine diamond created in a controlled laboratory environment. It matches mined diamonds in hardness, refractive index, thermal conductivity, and durability—offering the same beauty and longevity with a smaller environmental footprint and no ethical concerns.
• Round Brilliant Cut: Engineered with precision to maximize light reflection and refraction. This iconic cut enhances the diamond’s fire, scintillation, and overall brilliance, ensuring the stone catches and dances with light from every angle.
• Three-Prong Martini Setting: Elevates the diamond above the chain to allow maximum light exposure through the crown and pavilion. This secure, open-style mounting showcases the full face of the stone while offering a refined, classic look that never goes out of style.
• 14k White Gold Chain & Mounting: Made from premium 14k white gold, this metal resists tarnish, maintains its brilliant shine, and provides a sleek, modern backdrop that complements the diamond’s radiance. It’s both durable and hypoallergenic, ideal for sensitive skin.

Why Choose Lab Grown Diamonds?

At Carbon Atelier, we believe luxury should be beautiful, responsible, and attainable. Our lab grown diamonds offer the same brilliance, durability, and fire as mined diamonds—but with a significantly lower environmental impact and no ethical concerns tied to mining practices.

Unlike cubic zirconia or moissanite, lab grown diamonds are 100% real diamonds. They possess the same crystal structure, refractive index, hardness (10 on the Mohs scale), and thermal conductivity as earth-mined stones. The only difference lies in origin: one forms deep underground over billions of years, while the other is grown in a matter of weeks using advanced technology that replicates natural processes.

By choosing lab grown jewelry like this pendant, you support innovation, reduce carbon emissions, and avoid potential human rights issues associated with traditional diamond mining. You still receive a certified, high-quality gemstone set in exquisite craftsmanship—just with a clear conscience and a smarter investment.

Carbon Atelier was founded by veteran designers passionate about merging artistry with accessibility. Every piece—from rings to pendants—is created with meticulous attention to detail, ensuring you receive not just a beautiful accessory, but a lasting symbol of grace and future brilliance.

Care & Maintenance

To preserve the beauty of your pendant necklace, store it separately in the protective travel pouch provided. Avoid contact with harsh chemicals, perfumes, lotions, or prolonged sunlight, which can dull the 14k white gold finish over time. Clean gently with mild soap, lukewarm water, and a soft-bristled brush. Rinse thoroughly and dry with a lint-free cloth before storing.

Regular cleaning helps maintain the diamond’s sparkle and keeps the metal looking radiant. With proper care, your pendant will remain a cherished part of your jewelry collection for years to come.
