Frequently asked questions

  • Is the diamond natural?

    Yes. A 1/5CT natural diamond with I-1 clarity and G-H color, chosen for maximum sparkle.

  • Why three prongs instead of four?

    Three prongs expose more of the diamond to light, increasing brilliance and fire while keeping the setting minimal and modern.

  • How long will it take to receive my order?

    Each piece is custom made for you. Please allow 10 business days for production unless the listing notes the item is already in stock.

  • Is it good for layering?

    Absolutely. The adjustable 16-18inch chain and minimalist design make it ideal for layering with other necklaces. Explore the Diamond Jewelry Collection >

More Details

One diamond. Three prongs. All the light in the room. Our three-prong diamond solitaire necklace features a 1/5CT natural diamond held in an open, minimalist setting that lets light enter the stone from every direction. The result is a necklace that sparkles with more fire and brilliance than a traditional bezel, while the three-prong design keeps the profile clean and modern.

Suspended on a 16-18inch adjustable cable chain in 14K gold, this is the diamond necklace that works with everything. Layer it, wear it solo, give it as a milestone gift, or buy it for yourself because one perfect diamond is sometimes all you need.

Why You'll Love It

  • The three-prong setting maximizes light, giving the diamond more fire and brilliance than a closed setting.
  • A 1/5CT natural diamond with real presence in a minimalist, everyday-friendly silhouette.
  • Adjustable 16-18inch chain for versatile layering or solo wear.
  • Handmade in the US with 14K gold and ethically sourced diamond.
