    History, Types, Cultural Significance Of Round Brilliant Cut Lab Diamond Engagement Ring

    The round brilliant cut has remained the gold standard in diamond shapes for over a century. With 58 precision-cut facets, it is designed to reflect the maximum amount of light, resulting in exceptional fire and sparkle. Its balanced symmetry and timeless appeal make it a favourite for proposals, anniversaries, and milestone celebrations.

    Our collection of round brilliant cut lab diamond engagement rings offers a modern take on this classic style. Each ring is crafted in 100% solid 14K & 18K gold, available in white, yellow, or rose tones, and features a dazzling centre diamond that meets the highest standards of brilliance and quality.

    These are lab-grown diamonds, created in controlled environments to mirror the exact optical and physical properties of natural diamonds—but without the ethical or environmental costs of traditional mining. Each stone is IGI certified, giving you full assurance of its cut, colour, clarity, and carat.

    Whether you're drawn to a timeless solitaire, a sparkling halo, or a sleek pavé band, you’ll find a ring that speaks to your style and story. Round brilliant diamonds complement every hand shape and setting style, making them incredibly versatile and flattering.

    At The Karat Store, every ring is handcrafted by skilled artisans, undergoes a thorough quality inspection, and is securely delivered with love and care. This is more than just a ring—it’s a symbol of your future, made to shine for a lifetime.

    Each lab-grown round diamond is hand-selected for brilliance, symmetry, and fire. The rings are also nickel-free and hypoallergenic, making them perfect for sensitive skin and daily wear. From the centre stone to the setting, every element is built to last and shine.

    Certifications Provided

    Every round brilliant cut lab diamond engagement ring comes with an IGI certificate verifying its cut, colour, clarity, and carat. This certificate assures you that your diamond meets globally recognised grading standards.

    Your ring also includes a BIS hallmark to confirm its 14K & 18K gold purity, and a detailed invoice listing all specifications. These documents are not only important for authenticity and resale but also add confidence to your purchase. At The Karat Store, certification is never an add-on—it’s a promise.

    Craftsmanship

    Round brilliant diamonds require perfect symmetry and expert setting. Our skilled artisans handcraft each ring, placing the stone with precision and polishing the band to a flawless finish. Whether you choose a prong, bezel, or halo setting, every detail is carefully completed by hand.
