    History, Types, Cultural Significance Of Lab-Grown Diamond Jewelry

    Diamonds have always symbolised 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 jewellery, 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 UK? UK 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 jewellery 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 jewellery, you’re choosing quality that lasts and values that matter.

    Certifications Provided

    Every lab-grown diamond at The Karat Store comes with a certificate from IGI (International Gemological Institute)—one of the most trusted names in gem grading.

    In addition, each piece features:

    • A 14K & 18K gold purity stamp

    • A detailed invoice

    • A lab report confirming stone authenticity and quality

    Buying certified jewellery gives you peace of mind, confirming that your diamond is genuine, ethically created, and accurately graded. It’s proof of both beauty and integrity.

    Craftsmanship

    Our lab-grown diamond jewellery isn’t just made—it’s carefully crafted by skilled artisans who bring decades of experience to the bench.

    From precise prong settings to flawless polishing, each piece goes through multiple stages of attention and inspection. We ensure a perfect finish, secure stones, and a shine that lasts. Before it ships to you, your jewellery is individually inspected and approved by our quality team.

    You’ll feel the difference from the moment you open the box.
