A 1.5 carat round engagement ring is the classic choice. A round brilliant diamond has the most sparkle of any shape. Every ring on this page is made in 18K or 14K solid gold, with a lab-grown or natural diamond.

Prices

  • 18K gold, lab-grown diamond: $1,525 to $1,553
  • 18K gold, natural diamond: $5,700 to $13,200
  • 14K gold, lab-grown diamond: $1,275 to $1,303
  • 14K gold, natural diamond: $7,100 to $13,000

The carat weight in each ring's name is the total diamond weight. A solitaire carries all of it in the center stone. Rings with side stones split it across several diamonds, so they cost less at the same total weight.

How big a 1.5 carat round looks

A 1.5 carat round diamond measures about 7.4mm across. A 1 carat round measures about 6.5mm. Our 1.5 carat guide compares prices for every shape at this weight.

Setting styles

This page has solitaire, halo, side-stone, three-stone, pavé and toi et moi rings. A solitaire puts all the attention on the center stone. A halo adds a frame of small diamonds that makes the center stone look larger.

Certification

Natural center diamonds come with a GIA grading report. Lab-grown center diamonds come with an IGI grading report. The report ships with your ring. See sample reports.
