Discover Timeless 1 Carat Round Cut Lab Grown Diamonds
The Perfect Size for Classic Brilliance
A 1 carat round cut diamond represents the gold standard of diamond excellence and the most sought-after size globally. At this carat weight, the round brilliant's iconic 58-facet design is perfectly showcased, creating that signature sparkle that has captivated hearts for over a century. Round brilliants account for nearly 75% of all diamonds sold worldwide, and there's a compelling reason—their mathematically optimized proportions deliver unmatched light performance. At 1 carat (measuring approximately 6.5mm in diameter), the round shape provides substantial presence while remaining refined for everyday wear. Our 1 carat lab grown round diamonds are created using advanced CVD and HPHT technology, producing stones that are physically, chemically, and optically identical to mined diamonds while offering up to 70% savings—allowing you to invest in premium Excellent or Ideal cut grades that maximize brilliance.
Why 1 Carat is the Most Popular Choice
At 1 carat, round brilliant diamonds achieve the perfect balance—large enough to make a meaningful statement and showcase exceptional sparkle, yet refined enough for comfortable everyday wear and versatile styling. This size has become the benchmark for engagement rings worldwide, offering substantial visual impact without being overly large. The 1 carat round's 6.5mm diameter provides excellent finger coverage and presence, allowing you to fully appreciate the 58 precisely aligned facets working in perfect harmony to create maximum brilliance, fire, and scintillation. This carat weight represents the sweet spot where size, value, and wearability converge, making it ideal for those who want a classic diamond that will never go out of style.
IGI Certified Quality with Optimal Cut Grades
Every 1 carat round diamond in our collection comes with IGI certification—the international standard for diamond grading trusted across all major markets. We prioritize Excellent and Ideal cut grades to ensure maximum light performance and that signature round brilliant sparkle. Round cuts are the most forgiving shape when it comes to color, so near-colorless grades (G-H) provide exceptional value while appearing perfectly white when set. VS2 clarity typically provides excellent eye-clean stones, as the brilliant faceting helps mask minor inclusions. Each certificate provides complete transparency on all specifications including cut, color, clarity, carat weight, measurements, and proportions, giving you confidence whether you're shopping from Mumbai, Dubai, London, or New York.
The Timeless Choice for Every Occasion
A 1 carat round cut diamond is the quintessential choice for engagement rings, representing timeless elegance and enduring love. This size works magnificently in every setting style—classic solitaires that let the brilliance shine, stunning halos that amplify the sparkle, elegant three-stone designs, vintage-inspired settings, and modern bezel or tension settings. The perfectly symmetrical shape ensures the diamond looks beautiful from every angle. Beyond engagement rings, 1 carat rounds make breathtaking stud earrings (0.50 carat each), elegant pendants, and sophisticated statement jewelry. The substantial size and universal appeal ensure your diamond will be treasured for generations.
