The La Florale Royale 18K Buttercup 12ct Natural Diamond Tennis Necklace is a rare expression of timeless beauty, artistry, and refined luxury. Crafted in luminous 18K solid gold, this exceptional necklace features the iconic buttercup setting—an elegant, petal-shaped mount that gently cups each diamond, enhancing its radiance with a soft, floral glow. The effect is a necklace that feels romantic, feminine, and wonderfully sculptural.
Adorned with an extraordinary 12 carats of natural diamonds, each stone is thoughtfully selected for VS2 clarity and G-color brightness, ensuring a harmonious, high-definition sparkle across the entire length of the piece. The diamonds rest beautifully along the neckline at a 16.5-inch length, offering a classic, collarbone-skimming fit that complements both contemporary and vintage-inspired styles.
The buttercup setting lifts each diamond slightly, allowing light to dance through its facets while creating the illusion of fuller, more dimensional brilliance. Whether worn solo as a statement piece or layered with delicate chains, it delivers an undeniably regal presence.
Certified by GIA and BIS hallmarked, this necklace embodies authenticity, craftsmanship, and heirloom-level excellence—an investment in beauty that will be cherished for generations.

Frequently Asked Questions
What occasions is this necklace best suited for?
This necklace works for both everyday wear and special occasions — the solid gold setting and diamond stone dress up simple outfits while still being subtle enough for daily use.
What's the price range for this tennis diamond necklace across different gold karats?
At The Karat Store, this tennis diamond necklace starts at $6,318 in 10K gold, $7,128 in 14K gold, and $8,100 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 chain length should I choose for this necklace?
Chain length is a matter of preference and where you want the pendant to sit: 16" sits at the collarbone, 18" is the most versatile everyday length, and 20"+ sits lower for a more dramatic look. Check the size options on this page for what's available.
What's the best way to keep this diamond 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.
