A ring that celebrates your bonds.
Sometimes, less is more—and more refined. Our 0.9 carat diamond rings, available in moissanite, lab-grown, and natural diamonds, strike the perfect balance between elegance, brilliance, and everyday wear ability. Expertly handcrafted in solid 14K and 18K gold, each ring is designed to shine just as brightly as a full carat, with all the beauty and none of the compromise.
Choose the sparkle that best fits your story—GIA-certified natural diamonds, IGI-certified lab-grown diamonds, or GRA-certified moissanite—each set with care and craftsmanship to create a ring that reflects your love in every way.
Shipped securely and delivered across the USA in 12 to 22 days, all orders include gold purity stamps, gemstone certification, and tamper-proof packaging.
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 maximize value without compromising brilliance or impact.

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.
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 color 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.
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.
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.
