What should you look for when choosing a diamond necklace?

Deciding on a diamond necklace, for yourself or as a gift, usually comes down to the stone itself. The way the diamond is cut, its origin, and how it’s set, will influence how the piece is worn. 

In our collection, you will find:

  • Certified natural diamond necklaces in your preferred cut and clarity

  • Lab-grown diamond necklaces with sustainably-grown brilliance

  • Pink and champagne diamond pendants with soft, distinctive hues

  • Round, oval, pear and princess-cut stones set in pendants, link chains, and tennis necklaces
