History, Types, Cultural Significance Of Lab-Grown Diamond Jewelry
Diamonds have always symbolized love, strength, and beauty. Today, lab-grown diamonds offer those same qualities—just with a cleaner origin story. First created in the 1950s for industrial use, lab-grown diamonds have now become a popular choice in fine jewelry, thanks to improved quality, accessibility, and ethical appeal.
Our lab-grown diamond collection includes everything from classic solitaires and halo engagement rings to tennis bracelets, ear studs, and modern pendants. Each piece is designed with care, showcasing the fire and brilliance lab-grown diamonds are known for—without the inflated price tag of mined diamonds.
Why are they so loved in the USA? American shoppers value ethical sourcing, eco-conscious choices, and great value for money—and lab-grown diamonds deliver on all fronts. They’re chemically identical to natural diamonds, just grown above ground in a controlled environment using clean energy and minimal impact on nature.
So whether you’re proposing, celebrating, or simply upgrading your everyday look, lab-grown diamond jewelry is a meaningful and smart choice. At The Karat Store, every design is set in solid 14K & 18K gold, IGI certified, and made to shine for a lifetime.
Quality of Material Used
Our lab-grown diamond pieces are always made with 100% solid 14K & 18K gold—never plated or gold-filled. This ensures long-lasting wear, durability, and a true sense of luxury.
Each diamond is ethically grown, carefully selected for clarity and brilliance, and securely set by hand. These designs are hypoallergenic, perfect for sensitive skin, and ideal for both daily wear and special occasions.
When you choose our lab-grown diamond jewelry, you’re choosing quality that lasts and values that matter.
Certifications Provided
