    History, Types, Cultural Significance Of 1.5ct oval cut diamond ring

    A 0.9-carat stone offers all the visual presence of a 1-carat diamond, at a more accessible price point. To the eye, it looks nearly identical in size, but allows you to maximise value without compromising brilliance or impact.

    At The Karat Store, you can choose:

    • Natural Diamond Rings (GIA Certified) – Uniquely formed in nature, with timeless value

    • Lab-Grown Diamond Rings (IGI Certified) – Identical to natural diamonds, ethical and budget-friendly

    • Moissanite Rings (GRA Certified) – Exceptional fire and brilliance at a fraction of the price

    • Cuts available: Round, oval, emerald, cushion, pear, princess

    • Designs: Solitaire, halo, three-stone, hidden halo, vintage-inspired

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

    This is the sweet spot for those who want elegance, affordability, and standout sparkle—all in one timeless ring.

    Quality of Material Used

    At The Karat Store, we believe that an engagement ring should be more than beautiful—it should be made to last a lifetime. That’s why every 0.9 carat ring in our collection is crafted using only the highest quality materials, beginning with 100% solid gold.

    We never use gold plating or gold-filled metals. Instead, you’ll receive your ring in either solid 14K or 18K gold, known for its durability, rich hue, and long-term value:

    • 14K gold is alloyed for superior strength, ideal for everyday wear without losing its shine

    • 18K gold contains a higher percentage of pure gold, giving it a deeper, warmer colour with a luxurious finish

    Available in yellow, white, and rose gold, each piece is hypoallergenic and nickel-free, making it perfect for even the most sensitive skin.

    Certifications Provided

    All our rings are made using 100% solid 14K or 18K gold, never plated or filled. You can feel the difference in weight, warmth, and durability.

    Every gemstone—whether diamond or Moissanite—is ethically sourced, hand-selected, and certified:

    • GIA for natural diamonds

    • IGI for lab-grown diamonds

    • GRA for Moissanite

    Each ring is delivered with a detailed invoice, official certification, and hallmarked gold purity—so you know exactly what you’re wearing and why it matters.

    Craftsmanship

    Each 0.9 carat ring is handcrafted by experienced goldsmiths, who shape, set, and finish every detail with care. From the smoothness of the band to the precision of each prong, our artisans make sure your ring isn't just stunning—it's secure, comfortable, and made to last a lifetime.

    Before shipping, every ring undergoes a multi-point inspection to ensure it meets our highest standards of finish and beauty.
