A tennis or eternity necklace is the pinnacle of classic luxury—featuring a seamless strand of brilliant diamonds that circle the neck in perfect harmony. At The Karat Store, our lab grown diamond tennis & eternity necklaces offer this coveted style with the added value of ethical sourcing and modern craftsmanship.

Each necklace is handcrafted in 100% solid 14K & 18K gold, available in white, yellow, or rose tones. The diamonds are lab-grown, identical in composition and brilliance to natural diamonds, but sustainably created using cutting-edge technology. These diamonds are IGI certified, ensuring every piece meets strict standards for cut, clarity, and carat weight.

Choose from delicate tennis chains with smaller carat sizes for everyday elegance, or go bold with high-carat eternity collars that bring red-carpet glamour to your wardrobe. All stones are meticulously set in secure prongs or bezels, offering both brilliance and lasting durability.

These necklaces are beloved across the USA for their timeless design and upscale finish—perfect for weddings, anniversaries, milestone gifts, or just because. Their symmetrical beauty and radiant flow make them ideal as heirlooms or luxury staples that elevate even the simplest outfit.

Quality of Material Used

We craft every tennis and eternity necklace using 100% solid 14K & 18K gold, never plated or filled. This ensures long-term shine, durability, and comfort. Available in white, yellow, or rose gold, our metals are nickel-free and hypoallergenic, safe for daily wear.

The lab-grown diamonds used in our necklaces are chosen for their unmatched clarity and consistent brilliance. Each stone is hand-set to ensure symmetry, security, and a seamless finish. These are not just beautiful pieces—they’re crafted for real life.

Certifications Provided

Every lab-grown diamond tennis and eternity necklace includes a certificate from IGI (International Gemological Institute) verifying the 4Cs—cut, color, clarity, and carat weight—of the diamonds used.

Each piece also carries a BIS hallmark to confirm the 14K & 18K gold purity, and is accompanied by a detailed invoice with your order’s specifications. With these certifications, you’re investing in not just sparkle, but verified value and peace of mind. That’s the standard we uphold at The Karat Store.

Craftsmanship

Crafting a tennis or eternity necklace requires absolute precision and artistry. Our jewelers hand-set each diamond, ensuring perfect alignment, secure settings, and fluid movement. The result is a necklace that drapes gracefully and shines from every angle.

Each piece is polished by hand and goes through a multi-point quality check, including inspections for diamond consistency, chain flexibility, clasp security, and overall finish. What you receive is handcrafted fine jewelry, made with intention and built to shine for a lifetime.
