History, Types, Cultural Significance Of Radiant Cut Lab Diamond Engagement Ring
The radiant cut diamond brings together the best of both worlds—brilliant sparkle and sleek symmetry. Its rectangular or square shape is softened by trimmed corners and faceted with 70 tiny surfaces that reflect light from every direction. The result? A high-sparkle diamond that flatters every finger and setting.
Our collection of lab-grown radiant cut engagement rings showcases this unique shape in all its glory. Choose from classic solitaires, pavé bands, halo frames, and east-west orientations—all handcrafted in solid 14K & 18K gold. Whether you prefer white, yellow, or rose gold, each ring is made to highlight the brilliance of the radiant cut.
These diamonds aren’t just visually stunning—they’re also ethically created. Our lab-grown diamonds are chemically and optically identical to mined stones, but they’re grown using sustainable methods with no conflict sourcing. That’s why more and more couples across the China are choosing lab diamond jewellery for their engagement rings—it’s smart, ethical, and beautiful.
Radiant cuts are especially popular for their modern feel and unmatched fire. Their versatility makes them perfect for a range of styles—from bold and contemporary to vintage-inspired. Every ring in this collection is crafted by skilled artisans, quality-inspected, and shipped with love.
When you choose The Karat Store, you’re not just choosing a diamond—you’re choosing a conscious commitment to quality and craftsmanship.
Quality of Material Used
We craft every radiant cut engagement ring using 100% solid 14K & 18K gold, never plated or filled. This ensures the ring maintains its integrity, shine, and structure over a lifetime. Available in white, yellow, and rose gold, each ring is tailored to your personal style and built to last.
Our lab-grown radiant diamonds are selected for their symmetry, clarity, and brilliance. Each piece is also hypoallergenic and nickel-free, making it safe for sensitive skin and ideal for daily wear. Designed for beauty and strength, your ring is made to shine today—and every day after.
Certifications Provided
Your radiant diamond deserves real credentials. That’s why every engagement ring in this category comes with an IGI certificate that confirms your lab-grown diamond’s cut, colour, clarity, and carat weight.
We also provide a BIS hallmark on all rings to certify the purity of the 14K & 18K gold, and include a detailed invoice outlining your ring’s specifications. These certifications ensure the authenticity, insurability, and long-term value of your jewellery.
At The Karat Store, we make sure every detail is verified—because buying fine jewellery should come with full peace of mind.
Craftsmanship
Radiant cut diamonds require an expert setting due to their sharp edges and faceted brilliance. At The Karat Store, our skilled artisans handcraft each ring with meticulous attention, ensuring the diamond is protected, aligned, and framed to perfection.
From prong setting to final polishing, every ring goes through a multi-step inspection process, checking for security, brilliance, and finish. Each radiant cut ring is a work of art, built to stand the test of time and worn with confidence.
This is handcrafted fine jewellery made to celebrate love, with sparkle in every angle.
