    History, Types, Cultural Significance Of Solitaire Setting Lab Diamond Engagement Ring

    A solitaire engagement ring is the ultimate expression of love and elegance. It features a single, striking diamond as its centrepiece—no side stones, no distractions. The design speaks for itself: confident, classic, and enduring.

    At The Karat Store, our solitaire setting lab diamond engagement ring combines tradition with modern ethics. Every ring is made using solid 14K & 18K gold in your choice of white, yellow, or rose gold. The diamonds are lab-grown using advanced technology, offering the same chemical, physical, and visual characteristics as mined diamonds—but with a lower environmental impact and zero conflict sourcing.

    Choose from a variety of cuts, including round brilliant, oval, emerald, cushion, pear, and more. You can also choose your preferred setting style—four-prong, six-prong, bezel, or cathedral—to reflect your taste. Solitaire settings are extremely versatile and pair beautifully with almost any wedding band style.

    Solitaire rings are especially popular in the UK for their timeless charm and focus on the diamond’s natural beauty. Whether you're planning a surprise proposal or shopping together, these rings offer a simple, stunning way to celebrate love.

    Each piece in our collection is handcrafted by skilled artisans, thoroughly inspected for quality, and shipped with care. If you're looking for a ring that puts the spotlight exactly where it belongs—on your love story—this is the collection for you.

    Quality of Material Used

    Every solitaire ring is made using 100% solid 14K & 18K gold, not plated or filled. This ensures your ring maintains its beauty, durability, and value over time. Choose from yellow, white, or rose gold depending on your style.

    We use lab-grown diamonds that are hand-selected for cut, clarity, and brilliance. These diamonds are not only stunning but also eco-friendly and ethically sourced. Our rings are nickel-free and hypoallergenic, making them perfect for everyday wear and safe for sensitive skin.

    Certifications Provided

    Each solitaire lab diamond engagement ring from The Karat Store comes with a certificate from IGI (International Gemological Institute). This ensures the authenticity of your lab-grown diamond and confirms its 4Cs—cut, color, clarity, and carat.

    All our gold is also BIS hallmarked, validating the purity of your 14K & 18K solid gold. You’ll receive a detailed invoice with every purchase for added transparency. Certification ensures your jewelry meets international standards and adds value, trust, and peace of mind to your purchase.

    Craftsmanship

    A solitaire ring demands perfect balance—and that’s exactly what our artisans deliver. Each diamond is expertly hand-set to highlight its brilliance while ensuring long-term security. Whether in a classic prong or sleek bezel setting, the focus is always on letting the diamond shine.

    Our craftsmen meticulously shape, polish, and finish each ring using traditional techniques and modern precision. Before it ships, every ring undergoes a multi-point quality check for setting strength, symmetry, and shine. The result is handcrafted fine jewelry that’s ready for life’s biggest moments.
