About this 1.5ct natural round diamond

This 1.5ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 2428351005. Listed at 18 retailers as of October 27, 2026, with prices from $5,104 to $11,718, a $6,615 spread on the same certified stone. NZ Jewellers lists it at $11,718. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
