Real diamonds, real prices

Every necklace on this page pairs a specific diamond from our natural or lab grown inventory with one of our pendants. The price you see is the finished necklace: pendant, chain and that exact diamond. We refresh the stones every day, so a diamond that sells is replaced the next morning.

Tap a necklace to change the metal or chain length, see the diamond's details, or swap in another stone.

Bezel, prong or hidden halo

  • Bezel: a thin rim of metal around the diamond. Smooth, secure and easy to wear every day.
  • Four-prong and V-prong: small claws hold the diamond and let in the most light. V-prongs protect the tips of pear and princess cuts.
  • Pavé bail: small diamonds along the loop that holds the chain.
  • Hidden halo: a ring of small diamonds under the center stone, seen from the side.

Natural or lab grown

  • Natural: mined diamonds, each with a GIA report.
  • Lab grown: the same material as a mined diamond, grown in a lab, each with an IGI report, for a fraction of the price.
  • Lab grown necklaces carry a Lab grown label, and the switch above the necklaces shows one kind or both.

Diamond solitaire necklaces FAQs

Is the diamond in each solitaire necklace a specific stone?

Yes. Each necklace on this page is paired with one graded diamond from our inventory. If that stone sells before your checkout, we show you the closest matches.

What size diamond is best for a solitaire necklace?

Half a carat reads as delicate and suits everyday wear; 1 carat is clearly visible across a room. A pendant sits farther from the eye than a ring, so many people choose a slightly larger stone.

Should I choose a bezel or prong setting?

A bezel wraps the diamond in metal, so it is smooth against clothing and protects the edge. Prongs show more of the diamond and let in more light.

Is the chain included?

Yes. The price on each necklace includes the pendant, the chain and the diamond.

How much does a diamond solitaire necklace cost?

Most solitaire necklaces here are about $1,250 to $4,200 with a natural diamond and $630 to $1,350 with a lab grown one. The Transparency Manifest on each necklace breaks that price down.
