    History, Types, Cultural Significance Of Lab-Grown Diamond Engagement Ring

    Engagement rings carry meaning that goes beyond the sparkle—they represent love, commitment, and shared dreams. But today’s couples are choosing to express that meaning in modern, mindful ways. Our lab-grown diamond engagement rings under 700$ are made for those who value responsibility, craftsmanship, and smart spending.

    Lab-grown diamonds are physically and chemically identical to mined diamonds, but they’re created using eco-friendly technology in ethical environments. That makes them a perfect option for couples who want to reduce their environmental impact while still celebrating with something beautiful.

    In this curated collection, you’ll find elegant solitaires, chic minimalist bands, vintage-inspired shapes, and petite halo styles—each one handcrafted in 14K & 18K solid gold and built to last. Whether you prefer timeless round cuts, cushion shapes, or geometric emeralds, there’s a ring here that reflects your taste and your values.

    These rings are not just budget-friendly—they’re packed with value. You’re getting certified lab-grown diamond jewellery, handcrafted by expert artisans, and priced fairly without the traditional markup. With the growing trend of lab diamonds across the UK, these rings are increasingly popular with shoppers who want quality and conscious choices.

    Ideal for proposals, promise rings, or second-time engagements, these rings offer exceptional brilliance and meaning, all under $700. It’s a new way to say “forever,” without overspending.

    Quality of Material Used

    Each ring in this collection is made with 100% solid 14K & 18K gold—never plated, never filled. We offer yellow, white, and rose gold options to match your personal style. Our lab-grown diamonds are carefully selected for fire, brilliance, and ethical origin.

    Hypoallergenic and nickel-free, these rings are safe for sensitive skin and comfortable enough for daily wear. The diamonds are expertly set using secure prongs or bezel techniques to ensure lasting durability and shine. It's affordable luxury, made to last a lifetime.

    Certifications Provided

    We believe every diamond should come with proof. All our lab-grown diamond rings under $700 include an IGI certificate that verifies the diamond’s authenticity and quality, including cut, clarity, and carat weight.

    In addition, each piece is BIS hallmarked to confirm the gold’s 14K & 18K purity. We also provide a detailed invoice for every purchase, outlining the product specifications for transparency and trust. Buying certified jewellery ensures value, future resale options, and confidence in your investment.

    With The Karat Store, you’re not just buying a ring—you’re buying certified craftsmanship backed by integrity.

    Craftsmanship

    We take pride in the fine details. Each engagement ring is handcrafted by skilled artisans, using traditional jewellery-making techniques and modern precision. From shaping the band to setting each stone, our jewellers put care into every step.

    The diamonds are set securely with expert prong or bezel settings, followed by polishing for a mirror-like finish. Before shipping, every ring goes through a multi-step quality inspection, checking the stone setting, symmetry, polish, and shine.

    The result? A handcrafted fine jewellery piece you’ll be proud to wear or gift—made with care, made to last.
