The Emerald Octagon Grace 18K Gold Tennis Necklace is a refined celebration of vivid color, precision cutting, and timeless sophistication. Handcrafted in radiant 18K solid gold, this elegant necklace features a continuous line of natural emeralds shaped into striking 2.5 mm octagon cuts—a geometric profile that highlights the gemstone’s depth, clarity, and signature green brilliance.
With a total of 7 carats of emeralds, each stone is carefully selected for its rich hue and uniformity, creating a harmonious flow of color that sits gracefully along the neckline. The octagon detailing enhances the emerald’s vibrancy, adding an architectural elegance that sets this piece apart from traditional tennis necklace designs.
The classic silhouette makes it effortlessly wearable—perfect for both everyday sophistication and elevated evening style. Whether layered with minimalist chains or worn as a bold standalone statement, the necklace adds an element of polished luxury to every look.
Available in white, yellow, or rose 18K gold, each metal tone brings out a unique dimension of the emerald’s natural green glow: crisp in white gold, warm and regal in yellow gold, soft and romantic in rose gold.

Frequently Asked Questions
Is an tennis emerald necklace a good gift?
Yes. Emerald necklaces are a popular gift for birthdays, anniversaries, and holidays — a meaningful step up from costume jewelry, and emerald set in solid gold holds its value and appearance far longer than plated pieces.
What's the price range for this tennis emerald necklace across different gold karats?
At The Karat Store, this tennis emerald necklace starts at $5,070 in 10K gold, $5,720 in 14K gold, and $6,500 in 18K gold — all solid gold, not plated.
Should I choose 10K, 14K, or 18K gold for this necklace?
18K gold (75% pure) has the richest color and softest feel. 14K gold (58.3% pure) is the most popular balance of durability and value. 10K gold (41.7% pure) is the most affordable and most scratch-resistant.
Is this necklace solid gold all the way through, or just gold-plated?
This necklace is solid gold throughout, not gold-plated — the karat purity runs all the way through the metal, not just a surface layer. Unlike plated jewelry, it won't flake, discolor, or expose base metal over time, and it carries a karat hallmark stamp as proof of authenticity.
What occasions is this necklace best suited for?
This necklace works for both everyday wear and special occasions — the solid gold setting and emerald stone dress up simple outfits while still being subtle enough for daily use.
What's the best way to keep this emerald necklace looking new?
Soak briefly in warm water with a drop of mild dish soap, gently brush with a soft-bristled brush, rinse, and pat dry. Avoid chlorine, harsh chemicals, and ultrasonic cleaners, and remove before swimming, showering, or exercising.
