    History, Types, Cultural Significance Of 3ct emerald cut diamond ring

    The emerald cut is a favourite for its understated elegance. With its long, sleek facets and step-cut design, it reflects light in dramatic flashes instead of intense sparkle, making it the ultimate choice for those who appreciate sophistication over showiness. At 3 carats, it offers a bold presence, without being overly flashy.

    At The Karat Store, you can choose:

    • GIA-certified natural diamonds – Rare, luxurious, and timeless

    • IGI-certified lab-grown diamonds – Eco-conscious, identical in structure and sparkle

    • GRA-certified Moissanite – Brilliant, durable, and exceptional value

    • Available in solid 14K or 18K gold – yellow, white, or rose

    • Customise your ring with halo, hidden halo, three-stone, solitaire, or pavé settings

    Whether you're drawn to vintage glamour or modern minimalism, our emerald cut rings are made to reflect your unique style and lasting commitment.

    Quality of Material Used

    We use only 100% solid 14K and 18K gold—never plated, filled, or vermeil. Every band is crafted to feel substantial, resist tarnishing, and maintain its brilliance over time.

    • 14K gold offers strength and durability—ideal for everyday wear

    • 18K gold has a deeper, richer colour with higher purity for those who want a more luxurious look

    All metals are nickel-free and hypoallergenic, ensuring comfort for even the most sensitive skin.

    Our gemstones are equally exceptional—certified, ethically sourced, and hand-selected for superior cut, clarity, and radiance:

    • GIA for natural diamonds

    • IGI for lab-grown diamonds

    • GRA for Moissanite

    Each 3-carat stone is precision-cut to enhance the emerald shape’s unique flash effect and elegant proportions.
