Buying guide

How rose gold looks with a 3 carat center

Rose gold gets its pink tone from copper in the alloy. The warm metal makes a colorless lab-grown diamond look brighter by contrast, and it suits warm and olive skin tones well. 10K rose gold has the deepest pink and is the hardest of the three karats; 18K has a softer blush and more gold in it. A 3 carat lab-grown diamond ring in rose gold reads as vintage-leaning even in a simple solitaire.

Choosing a style

  • Solitaire: the center on its own, on a plain band or a pavé band.
  • Halo and hidden halo: a ring of small lab-grown diamond accents around the center, or tucked under it so it shows from the side.
  • Side accents: pear or marquise stones beside the center, mixed with rounds.
  • Three stone: a side stone on each side of the center.
  • Cathedral: raised shoulders that sweep up to the center, here with a graduated pavé band.

Picking a shape

Elongated shapes such as oval, pear, marquise and emerald spread a 3 carat center over a longer outline, so they cover more of the finger. Round and cushion give the most sparkle. Princess and Asscher are square and crisp, and heart is the most unusual choice for a center this size.
